Internal CCTV systems

Recommended Posts

We have at the moment a cobbled together CCTV system around the theatre using UHF modulators and a bunch of old TVs. We are in reception areas for two transmitters. As part of an effort to tidy up and improve the system, I'd like to filter out the more distant transmitter. Conveniently, the wanted channels on the better transmitter are all below Ch35 (583MHz). Can anyone point me towards a brick-wall or steep low pass filter at this sort of frequency?


I have a feeling I know who will know the answer. :D
