Notch type Antenna Filter for 1.2GHz - 1.3GHz TX

This coax stub type notch filter installs on the 1.3GHz FPV video transmitter. It is used to attenuate second harmonic interference that may reduce the range of a nearby 2.4GHz R/C receiver.

Installation is as simple as removing the video transmitter's antenna and then attaching the filter. Works with all popular 1.3GHz transmitter antennas that use standard SMA connectors.

Please note that this filter will not help reduce interference to nearby GPS receivers.
