Has anyone got any of the two items lurking in their lofts/garages/workshops that I could buy please or know where I can buy them from?
I already have a Triax 5G filter on the freeview side before combining with the 10 CCTV mods to stop the 4G and 5G signals trampling all over my ch 50 to 68 analogue signals.
Only trouble is the noise floor in Ch's 21 to 48 is getting through from the 10 modulators bank and it is degrading the signal to noise ratio of all my freeview signals.
So I need to put a Ch 48 to 68 bandpass filter between the modulator bank and the combiner......
I have already tried a Triax TMC 4648 but it is totally unscreened and it actually makes the problem worse. (this is a Group K aerial and group CD aerial combiner.
I could try putting the aerial combiner into a metal box but would rather try a screened Group CD bandpass filter first!
Looking forward to the replies!
