Moxon antenna i made was not so good tuned as expected, so I made another one.

Now it looks much better 🙂

Moxon Antenna for LRS TX

May

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.
