Verizon cell towers in Arizona use the 700 MHz band, and reception across the 700/800 MHz range is completely wiped out within several hundred yards (maybe as much as a quarter of a mile) of these towers.
My PSR-500 is useless across this range when near a Verizon tower here. I'm curious myself as to whether or not an SDS-100 would fare any better.
