Use this on your 433MHz RC transmitter to filter out interference in the 1.2-1.3GHz spectrum.

A bit fragile review by TonyLewis on 9/30/2016
With a diamond 433 antenna, the weight is just too much for this unit, you really have to be careful not to bend the sma connectors off, as they're only held together by the single antenna solder point and the friction-fit sma brackets. I highly recommend reinforcing before use.
