We highly recommend using this filter if you're using 433MHz UHF long range system, and want to protect your 900MHz, 1.2/1.3GHz or 2.4 GHz FPV video system from getting harmonics from the UHF transmitter.
Install this filter between your 433MHz UHF transmitter its antenna. The filter will suppress any harmonics of 433 MHz such as 866 and 1299 MHz. You can even double the amount of attenuation by installing two of these filters in series.
The performance of this filter is excellent, and you will be able to tell the difference by getting a much stronger, better and cleaner video signal.
Recommended for Dragonlink and EzUHF long range systems.
