Default Re: Spectrum Comms. Active Antenna problem

If you still get the overloading/cross modulation then the loop amplifier is the problem - no amount of filtering or radio gain reduction will get rid of it.
As I said, if the cross-modulation is taking place in the loop amplifier, no amount of attenuation subsequent is going to get rid of it.

It was connected to the ATU and Attenuator, 10dB, 20dB, 30dB and 40dB. It just got quiet, but the overloading signals are still there, not going away.
