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 🙂

Blejzyk FIRST – build log
I decided to use Blejzyk FIRST glider as my next FPV platform… So I 3d printed some parts, instead using wooden.
Li Ion batteries are not safe as you think
My Ranger catch fire after crash 🙁
CG Machine
An absolute must for RC hobbyists 🙂
Moxon Antenna for LRS TX
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.
DIY biquad antenna vs other ready to use antennas you can buy
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.
