Clearly I've got something set up improperly...
Quick example -- I'm using a BCT15 scanner with a Larsen SPEC800 antenna, mag mounted. I've also tried a tuned (2 3/4") whip. Both cause so much intermod(?) that at certain intersections where I know there are a lot of cell towers, I get absolutely no signal. Meanwhile, I know a guy who has basically the same setup as me (the only difference is that his antennas aren't mag mounted) and doesn't have intermod problems that are at all comparable to mine. The built in attenuator barely helps. I've also tried (as some have suggested) to use a VHF whip for 800 Mhz stuff, and it doesn't make a difference.
Thoughts?
