Experts help wanted RE: ADS-B

Post by Jdor » Mon Sep 10, 2018 10:55 am

Hi, I have the nooelec NEOSDR SMArt. I was using this to receive ATC which I no longer need. I would know like to use this solely for ADS-B reception and have some questions for the experts on here.

How much different or better would using the flight aware pro stick be (FlightAware ProStick Plus (ADS-B Specialty RTL-SDR)<the one inthe rtl-sdr shop?

Would using the NEOSDR SMArt with RTL-SDR Blog ADS-B Triple Filtered LNA (Bias Tee Powered) <the one inthe rtl-sdr shop be a more efficient option ? and is the NEOSDR even compatible with the filter

Antenas !! I have seen many differing setups, what is the best antenna for indoor use ?for ADS-B reception. Both homemade and commercial. I know very little about antennas. The antenna will be able to go in the loft but the roof is out of the question at the moment. Also how do DIY and commercial antennas compare to the standard one that comes with NEOSDR ? And also how do they compare to each other. for example how would this compare http://www.nooelec.com/store/sdr/ads-b- ... -5dbi.html to a home made one

This is SDR I have for those that are wondering http://www.nooelec.com/store/sdr/nesdr-smart.html

I don't mind spending on this hobby but not for the sake of it

thanks kindly for all your help and advice

The SMArt dongle is almost identical to the basic generic RTL-SDR design, so the FlightAware dongle with it's built in 1090 MHz low noise figure LNA and filter is substantially better at ADS-B reception.

Even better would be our RTL-SDR V3 together with our Triple Filtered ADS-B LNA. Note that the Triple Filtered LNA is bias tee powered, so your current SMArt dongle won't work with that LNA, because that dongle doesn't provide bias tee power.

I would recommend a proper ADS-B antenna, like the one sold by FlightAware https://amzn.to/2x2bfP7. Those small whip antennas you showed are pretty useless for any decent reception unless you're going portable on a plane.

Put the FlightAware antenna and Triple Filtered ADS-B LNA in the loft and use some high quality RG6 coax cable to get the signal down to your RTL-SDR V3. That's about the best setup you can get.
