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, this way any other signal higher than 433MHz such as harmonics will be powerfully attenuated.
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.
