Finally I found time to test it.
Months ago i started to develop custom firmware for cheap 1W LORA module, to use it as LRS RX/RX devices. Now it’s almost ready for testing 🙂
This is relay nice FPV glider 🙂 Build log
I recently bought simple sweep spectrum analyzer, and now i can measure and tune all my antennas. Moxon antenna i made was not so good tuned as expected, so I made another one. Now it looks much better 🙂
I decided to use Blejzyk FIRST glider as my next FPV platform… So I 3d printed some parts, instead using wooden.
My Ranger catch fire after crash 🙁
An absolute must for RC hobbyists 🙂
This is first Moxon antenna I made. It looks like having 5db more gain then RMILEC SRC771 1/2 Wave Length Antenna (according my simple measurements). As always my RF generator’s used to drive TX antenna, and Immersion RC power meter, connected to dipole antenna to measure signal level.
I made my biquad antenna i did some simple measurements to compare it to other antennas used for FPV. It is very simple, I used Semi-rigid Flexible RG40 cable, inserted into small brass tube to make antenna tuning possible.
