Buy RTL-SDR Dongles (RTL2832U)

Where to Buy RTLSDR RTL2832U DVB-T Tuner Dongles

The R820T2 RTL-SDR is currently the cheapest, most common and is the best in terms of general usability. The R820T2 has a frequency range of  24 – 1766 MHz (frequencies above 1.2 GHz may require cooling/heatsinking) and is fully 100% compatible with any software for the older R820T.

At we sell significantly improved RTL-SDR dongles at low prices with free shipping. See our announcement post on our V3 units for a full overview of all the features, or scroll down for our store. Also see our V3 users guide for information on using special features of our dongle. The V3 datasheet is available here. Our dongles come with the following improvements:

  • <1 PPM temperature compensated oscillator (TCXO) – Accurate tuning and almost zero temperature drift (2 PPM max. initial offset, 0.5-1 PPM temperature drift)
  • SMA female antenna port – Most dongles use the less common MCX or PAL antenna ports. SMA is more common, so more adapters and antennas are available for it. It is also more durable and has lower RF insertion losses.
  • R820T2 tuner – More sensitive than the older R820T tuner. 100% compatible with software for the older R820T.
  • 4.5V USB powered bias tee – Can be enabled by running a simple program (see V3 users guide). This allows the RTL-SDR to power low noise amplifiers (like the LNA4ALL and HABAMP) and active antennas through the coax cable.
  • Experimental: HF Direct Sampling Mode – Listen to 500 kHz – 24 MHz with direct sampling. Simply connect an HF antenna to the SMA port, and choose the Q-branch to use. There is a built in 25 MHz low pass filter, but additional HF filters may be required for optimal performance (e.g. to knock out strong MW AM).
  • Aluminium case and passive cooling – These units come stock with an aluminium case and passive cooling via a silicon thermal pad.
  • Various additional improvements compared to other RTL-SDRs – Higher quality passive components, a choke on the USB line to reduce USB noise, a much improved PCB design for significantly less internal spurs and noise, various break-out pads, improved ESD protection, additional bypass capacitors and ferrite power line chokes, improved front end matching circuit and a better LDO.

Stratux RTL-SDR (Low Power RTL-SDR)
Stratux RTL-SDR (Low Power RTL-SDR) – Limited Stock Only

Includes 1x Stratux Low Power RTL-SDR.

This is a modified RTL-SDR dongle designed for low power consumption. It uses a switch mode power regulator instead of a linear regulator which results in about 100 mA lower power usage. The trade off is additional RF noise in VHF, though these have been designed carefully so the noise is actually LESS than most other ‘nano’ sized dongles.

Stratux RTL-SDR dongles are designed for use in ADS-B reception on small aircraft, but they can also be used by anyone requiring lower power usage. For example on solar powered Raspberry Pi units. Note that these units have no enclosure, and do not have a TCXO. When installing in Zadig these show up as “Low Power V2”.

Produced by and resold by us at RTL-SDR Blog with free shipping for international customers. US customs can purchase from Amazon directly from Stratux.

Recommended accessories from other sellers


Probably the most important part of a radio system is the antenna. There is no one size fits all antenna, every different design will have a trade off. For instance, wide band antennas can receive more frequencies, but will have less gain at any one particular frequency. If you want to receive everything then get a wide band antenna. If you want to receive one frequency with optimal reception, find a tuned narrow band antenna.

Discone Antenna
Discone Antenna

Discones are wideband antennas. This makes them ideal for the RTL-SDR as using a Discone will allow you to receive at almost any frequency with decent performance.

FlightAware ADS-B Antenna
FlightAware ADS-B Antenna

A 1090 MHz ADS-B antenna from FlightAware. Is weather proofed and has 5 dB of gain. Uses an N-type antenna connector. See our review post for more information.

Outernet L-Band Patch Antenna
Outernet L-Band Patch Antenna

If you’re wanting to get into receiving and decoding L-Band satellites such as Inmarsat, Iridium and Outernet then this is the easiest way to get started. Combine it with the Outernet LNA for best results in the Iridium and Outernet bands. See our review post for more information.


The lowest frequency an RTL-SDR can comfortably tune to is about 24 MHz. An upconverter allows you to use your RTL-SDR on HF frequencies which are between 0 – 30 MHz. They work by shifting frequencies between 0 – 30 MHz “up” by a fixed amount into a frequency range that is receivable by the RTL-SDR.

SpyVerter Upconverter

Currently we recommend the SpyVerter as the upconverter of choice. Although it was designed to be used with the Airspy, it works perfectly with the RTL-SDR. It uses a 120 MHz oscillator, has excellent filtering and can be powered via USB cable or via the bias-tee on our RTL-SDR Blog dongles. The SpyVerter uses an innovative new architecture that reduces overloading, has better SNR than other options and can operate all the way down to DC.

With the above performance and features, the included metal case and adapters and at a similar or even lower price compared to other upconverters we think this one is the best value. See our review post for more information.

SV1AFN Upconverter
SV1AFN Upconverter

An alternative to the SpyVerter is the upconverter designed by SV1AFN.

It based on the ADE-1 mixer chip, uses a 200 MHz oscillator, has good filtering and works almost down to DC.

Ham-It-Up Upconverter
Ham-It-Up Upconverter

Another recommended option is the Ham-It-Up Upconverter.

This one like the SV1AFN is also based on the ADE-1 mixer, but uses 125 MHz oscillator and is based on an open source design. There is also a metal case available on Amazon and eBay. However, currently we would recommend the SpyVerter or SV1AFN over this option.

RF Filters

RF filters connect between your antenna and RTL-SDR dongle. They help to significantly reduce out of band interference and noise which is very helpful when trying to improve signal strength.

118 - 138 MHz Air Band Bandpass Filter
118 – 138 MHz Air Band Bandpass Filter

If you are monitoring ACARS or air traffic signals then you may want an air band bandpass filter if you find that you have lots of interference from nearby stations such as FM broadcasts and Pagers.

FlightAware ADS-B Filter
FlightAware ADS-B Filter

FlightAware sell a very affordable ADS-B band pass filter. Many users have reported significantly improved reception when they started using this filter. This is probably the best filter to get if you are interested in ADS-B. See our review post for more information.

ADS-B HABamp LNA + Filter Combo
ADS-B HABamp LNA + Filter Combo

We also highly recommend the ADS-B HABAmp for receiving ADS-B signals. This is a filter + LNA combination that works very well and will significantly improve ADS-B performance.

We’ve tested these ourselves with the activatable bias tee in our units and found them to definitely work very well.

Adam's ADS-B/H-Line/FLARM Filters
Adam’s ADS-B/H-Line/FLARM Filters

Adam (9A4QV) also sells some good low cost filters for ADSB, Hydrogen Line Radio Astronomy or FLARM.

The Hydrogen line is a physics phenomona that can be observed with an RTL-SDR dongle and FLARM is a protocol similar to ADS-B but used more often with gliders and helicopters.

Multi HF Bandpass Filter
Multi HF Bandpass Filter

This product is great for if you are using an upconverter together with your RTL-SDR, or other SDR. Contains seven band pass filters that range from 1.6 – 2.5 MHz, 2.5 – 4.7 MHz, 4.7 – 7.5 MHz, 7.5 – 14.5 MHz, 14.5 – 21.5 MHz, 21.5 – 33 MHz and 33 – 56 MHz.

Low Noise Amplifiers

If you have long runs of coax cable then a low noise amplifier (LNA) can help to significantly improve your reception. Coax cable is lossy and the longer it is the more your received signal is attenuated. By adding an LNA near the antenna this loss can be reduced.


The LNA4ALL is a very affordable wide band low noise amplifier that is very commonly used with the RTL-SDR. Has the ability to be powered externally from any voltage between 6V – 9V, or with a simple modification with 3V – 5V in bias tee mode.

We have tested the LNA4ALL in bias tee mode with the activatable bias tee in our units and found it to work well.

Other LNA's
Other LNA’s

There are also several low noise amplifier circuits that can be found very cheaply for sale on eBay and most will do a good job. Unfortunately most don’t provide a bias tee option like the LNA4ALL or HABamp does.

ADS-B HABamp LNA + Filter Combo
ADS-B HABamp LNA + Filter Combo

We also highly recommend the ADS-B HABAmp for receiving ADS-B signals. This is a filter + LNA combination that works very well and will significantly improve ADS-B performance.

We’ve tested these ourselves with the activatable bias tee in our units and found them to definitely work very well.

Outernet L-Band LNA
Outernet L-Band LNA

If you’re wanting to receive Iridium or Outernet L-band signals then this is the best LNA for the job. It works between 1525 – 1559 MHz, with a gain of 34 dB. It has an on-board filter as well to remove out of band interference.

Must be powered via a bias tee, and works fine with the bias tee on our V1, V2 or V3 dongles. See our review post here for more information.

Other Accessories

Active USB Extension Cable
Active USB Extension Cable

Ideally you want to get the RTL-SDR dongle as close to the antenna as possible. Normal USB cables have a length limit of about 5m before they stop working, but with an active USB cable this can be extended up to 10 to 15 meters.

We recommend these Monoprice cables as they have been reported to work successfully with the RTL-SDR dongle.

Active USB Extension Cable
RG6 Coaxial Cable

We recommend using RG6 coaxial cable for most links between your antenna and RTL-SDR. RG6 is low loss cable and it is also very cheap because it is used commercially with satellite TV installations.

RG6 is 75 Ohm cable. Note that the mismatch between 50 and 75 Ohm impedances is completely negligible for RX applications.

Clip on USB Ferrite Core
Clip on USB Ferrite Core

Noise and interference can sometimes be induced in the USB cable itself which can show up in the RF spectrum. To stop this noise use clip on ferrite cores on the USB cable. These cores help to suppress unwanted currents in the USB shield.

Raspberry Pi 3
Raspberry Pi 3

A Raspberry Pi is a credit card sized computer that runs Linux, or even Windows. With it you can connect an RTL-SDR, run a server, and then remotely send a signal or processed data such as ADS-B aircraft locations back via WiFi or Ethernet cable.


A USB on-the-go (OTG) cable is required to use the RTL-SDR on Android phones with software like SDR Touch and Wavesink. We recommend trying to find cables that come with power plugs so that you can use it with a power pack. Using an RTL-SDR can increase CPU usage which can quickly drain a mobiles battery.

9:1 Balun
9:1 Balun

If you are using a long wire or random wire antenna with a HF modded RTL-SDR or an upconverter you should use a 9:1 impedance transformer to get good SWR.

There are also several other alternatives available on eBay that use a larger iron core.

Wideband Noise Source
Wideband Noise Source

A wideband noise source can be used together with an RTL-SDR dongle to perform measurements on filters and to measure the SWR of an antenna.

See our tutorial here for more information.


Recommended alternative SDRs


We think the Airspy is the SDR with the best RX capabilities in the mid priced SDR market right now. It really shines when used in tough RF environments, such as those found in city and suburban areas. The Airspy is an excellent upgrade from an RTL-SDR dongle. Requires the SpyVerter upconverter add on to receive HF signals.

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP and HackRF.


Another good mid range SDR is the SDRplay RSP. This SDR is great value for the price and can receive HF frequencies without an upconverter, but it not as good as the Airspy when running in tough RF environments with many strong signals.

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP and HackRF.

Nooelec Nano 2+ RTL-SDR
Nooelec Nano 2+

This is an alternative RTL-SDR to the version we sell. This RTL-SDR is very small and is great for using with portable equipment such as mobile phones and tablets. Costs more than ours, is much noisier and doesn’t have as many features but it also comes with a TCXO.

E4000 RTL-SDR Dongle
E4000 RTL-SDR Dongle

The E4000 is more expensive as it has become rare since it has gone out of production. It has a frequency range of 52 – 2200 MHz with a gap from 1100 MHz to 1250 MHz.

The E4000 RTL-SDR dongle can still be bought from Nooelec on Amazon as well. Due to its rareness, the cost of the E4000 is slowly rising. These dongles used to sell for $20, but are now going for around $50-$100! Best to get them now if you need them before they sell out completely. Though note that for most cases an R820T2 unit is usually better.

HackRF One
HackRF One

The HackRF One is a relatively low cost TX/RX capable SDR. It is designed for radio experimenters and it has a very wide band frequency range from 1 MHz to 6 GHz, and a wide bandwidth of up to 20 MHz and an 8-Bit ADC. It is probably the most versatile SDR that exists at the moment, but in a compromise it does not have the best quality RX or TX performance. Thus it is perfect for experiments like reverse engineering and testing RF devices, but it is not intended to be used as a commercial radio or ham radio.


  1. Jon

    I ordered the RTL-SDR and antenna kit with economy shipping from China, and it arrived in the UK 5 days after dispatch, which is great.
    I am completely new to amateur radios, but setting up SDR# and the dongle was very simple, and I am surprised how good a reception I am getting on airband – even with the antenna indoors.
    I have made a minor alteration to the set-up which has enabled me to hear weaker signals much better. Between my laptop and the RTL-SDR dongle, I added a 2 meter USB extension lead and moved the dongle away from my laptop. I then added ferrite chokes to each end of the USB cable.

  2. mesodef

    Is there any updated ETA on when the RTL-SDR Blog v3 w/ antenna will be back in stock on amazon? I would like to order one and I’m debating ordering from china vs waiting for amazon stock (preferably choosing the faster option).

    • admin

      It’s hard to say because we just don’t know how long the import will take (sometimes it’s fast, sometimes not). Best case within a week, worst case probably about 2 weeks.

  3. Hans J. Albertsson

    You say repeatedly that we should buy these items from “worldwide chinese warehouse”, but there is no link, so HOW?

  4. PuJo

    Just checked Amazon 6/21/17 and the LTR-SDR BLOG is out of stock. When will these units be available again?

  5. kss

    It would be nice if I can purchase the SMA telescopic antennas that are bundled with the SDR sticks (separately). Do you have any plan on doing this?

    • admin

      Sorry no plans for now. Later in the year we’ll have a simple telescopic dipole kit which will be better than the stock antennas that we have now, and we plan to sell that separately.

    Need adapters – mcx female to mcx female for projects. can anyone point to adapters with ‘reasonable’ prices.

  7. John Leonardelli

    i bought the silver metal case upgrade and never received it. impossible now to track or recover my money. DO NOT BUY FROM THEM AND GET IT OFF EBAY AS THEY WILL SCAM YOU. WHAT A JOKE. they run the 90 day scheme to screw you over so u cannot complain

    • admin

      90-day scheme? You should have up to six months to open a claim on PayPal. We sell on eBay too, and the same protections provided by PayPal apply there and here as well. And we’re more than happy to issue a refund at our expense if a parcel gets lost in the mail, but we haven’t had any contact from you apart from here.

      Secondly, I just checked your tracking details (looked up your order from your name), and it shows that it was successfully delivered at your address on 3 April 2017 after 14 days in transit. If it’s missing from your mailbox you should contact us and also contact your countries postal agency to open an investigation ASAP.

    • happy customer

      I bought the AM BC filter, which was delivered to the east coast USA, from the Chinese warehouse in less than 2 weeks. It works perfectly and is very well made. No scams here!

  8. Steven Gibson

    I was about to order the “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas” from Amazon when it became unavailable. They still have the dongle by itself, but I was hoping to get the antennas as well. Are they available separately? Or will the SDR+antenna item be restocked soon? (Your description says the Chinese warehouse will be restocked in a couple days; I don’t know about Amazon.) Please advise.

  9. Slyker

    Since the release of “RTL-SDR V3” nearly half a year, it is expected the new version (V4) devices in the near future?

  10. JTee

    I am a frequent visitor to Hong Kong from the UK. In fact I am here at the moment. Is there any physical outlet here where I can purchase the RTL SDR v3 and accessories? I was expecting to find such a place in Sham Shui Po but have had no luck.


    • admin

      Sorry we don’t have any physical outlets, we’re an internet shop only. Some distributors and shops who buy wholesale might have physical outlets, but there are none in HK yet. You could always order to your hotel, but it costs the same to ship it directly to the UK.

    Delayed International Parcels: Please be aware that there are several delays in the international mail system at the moment for parcels sent out during late November and for the whole of December, even for priority ePacket EMS parcels. The main delay is with local customs agencies. Please be patient and give them time to arrive, as we have no control over customs processing times. Here are some additional reasons for the December delays.

    1) Christmas rush causing too many parcels and the backlog is still clearing, 2) Lack of aircraft space causing parcels to be delayed, 3) Congestion from lack of staff and space at customs and security screening on both ends, 3) Heightened security protocols in place at most western customs and security agencies causing huge delays, 4) Smog in China grounding several flights causing increased congestion, 5) Strike action from the post in the UK causing significantly increased congestion, 6) Poor winter weather causing many delayed flights.

    Our logistics agents, other peer sellers and ourselves have noted that in some cases US and other countries customs are holding EMS parcels without tracking updates for 6(!) or more weeks, before releasing them with no reason given for the delay.

    An official statement from the post for the USA is shown below, and the same applies to most other countries too:

    Earlier we informed you that due to service limitations imposed by airlines, coupled by extremely heavy peak volumes, there is presently congestion for airmail to some destinations in US. As a result we’re currently encountering delays on all outgoing mail and parcel delivery services to US. On behalf of the designated operator of the United States of America we would like to inform you that all of the five offices of exchange of the United States Postal Service are open and receiving mail. Please note that there are no embargos. Due to limited ground-handler staffing and equipment, coupled with the heavy peak volumes, all offices of exchange are experiencing heavy congestion. We will continue to take measures to minimize the impact and we will keep you informed of developments.

    One from Royal Mail which equally applies to other carriers too:

    Start date: Early December
    End date: Ongoing
    The United States Postal Service (USPS) has recently advised us of operational difficulties at the Chicago port of entry which may result in delay to the delivery of international mail from other countries including some Royal Mail items. US Zip codes affected are, 4xxxx, 5xxxx,6xxxx and 7xxxx. Multiple local logistical and customs issues have caused this situation and USPS are working with all concerned to return services to normal. Royal Mail is also doing everything possible to minimise any further potential delay.
    We apologise for any delays which are beyond our control and will update this information as soon as we know more.

    Does the v3 RTL-SDR dongle support DVB-T2? Or is a version planned that will support it? I ask because terrestrial TV transmission in India uses DVB-T2.
