RTL-SDR Blog L-Band Patch, Bullseye, YouLoop Sale

This Black Friday we are offering a discount on our L-Band Patch, Bullseye and YouLoop antennas in our store and marketplace listings! The sale will run until the end of November.

Our L-Band patch is an active design for receiving L-band satellites such as Inmarsat, Iridium, GPS and other satellites that transmit between 1525 - 1660 MHz (please note that you cannot use it for weak signals that require a dish like HRPT or GOES).

The Bullseye LNB is a TCXO stabilized LNB for the QO-100 geostationary amateur satellite and other Ku-band satellites.

The YouLoop is a super portable passive HF/VHF loop antenna designed for super low NF/MDS receivers like the Airspy HF+ Discovery.

  • L-Band Patch Antenna: US $59.95 $49.95
  • Bullseye LNB: US $29.95 $24.95
  • YouLoop: US $39.95 $31.96

Pricing includes free shipping to most countries. Please note that pricing does not include VAT and/or taxes which may be added for your country.

TechMinds: Building a 3D Printed 2.4 GHz Dual Feed Helix for QO-100

The Bullseye LNB that we have in our store is great for receiving the QO-100 amateur geostationary radio satellite which is available in some parts of the world. However it cannot be used to transmit to the satellite. Over on his YouTube channel Tech Minds shows us how to build a transmit helix antenna that connects to the Bullseye or other suitable LNB, resulting in a dual feed antenna.

The antenna that was built is based on DO8PAT's "Ice Cone Feed" design. The design requires some 3D printed parts for the mount and housing, as well as a copper wire helix, metal reflector and copper matching strip. The Bullseye fits onto the back of the helix mount. Once mounted on a dish Tech Minds shows that he was able to make contact with a friend via the QO-100 satellite with good signal strength.
