At this Circuit can you See a LC Filter For FPV Transmitter. If you Try to fly with your Flight Lipo aka Battery without a LC Filter you can See a Little Flicker in your "Screen/Monitor/Googles" if you use A LC Filter like in my Circuit but keep Attention the Lamp in this Circuit is your Transmitter if you Wanna Build your own LC Filter you will Need a Sink with 20 windings ( Kupper) and a Capacitor (100 - 500 µF and between your Transmitter Voltage like 7- 25 V) From the Battery Plus to the Sink in a Row to the Capacitor and the Capacitor Parallel to the Battery and Sink and the Minus wire to your Battery and then from the Capacitor Plus to your Transmitter and the Minus wire to your Minus on the Transmitter.
