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.

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

Installation is as simple as removing the antenna and then attaching the filter. Works with all popular 1.2GHz - 1.3GHz transmitter antennas that use standard SMA connectors.

37.00 USD

Thanks for the link, that website is a gold-mine of good information & parts!

Hello,

Sorry if I have forget something, but does it means that 1.3 Ghz video downlink can disturb a 2.4Ghz RC system??

By advance, thanks for your advised lights...

Yes it can.

1.3 x 2 = 2.6 (and thereabouts).

Its about Rx saturation. The noise floor is raised above the ability of the TX to provide a signal large enough for the Rx to see over the ambient noise.
