Low Pass Antenna Filter for 1.2GHz - 1.3GHz TX

Low Pass Antenna Filter for 1.2GHz - 1.3GHz TX

This Low Pass Filter is designed to attenuate the radiated second and third order harmonics on 1.2GHz - 1.3GHz wireless video transmitters. Ideal for reducing video transmitter interference to nearby 2.4GHz receivers.

Installation is as simple as removing the antenna and then attaching the filter. Works with all popular 1.1GHz - 1.3GHz transmitter antennas that use standard SMA connectors.

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