I have a dozen SDS200's in a newsroom, that are having a very hard time recieving a Phase 2 800MHz trunked site, that is hitting our 800MHz yagi with an indicated -50dBm. Full signal, but talkgroups will most of the time just flash for a fraction of a second on and off and never receive, or receive with massive error, like up to 120 error rate...at -50dBm. Trying lots of the filters, some, such as AUTO and NORM basically cause the scanner to receive nothing.
The cell phone tower we installed on top of the scanners is AT&T and Verizon, so we have 700MHz and 800MHz blasting 50 feet away from our receive antennas. What would the best filter be to use...I am assuming that 800MHz 3G/4G bands are causing the problem? See attached pic for the tower, and in the lower left of the pic, our tiny scanner antenna array.
