ive got about 50-55 feet between me and the discone i have above roofline.
i use the amp in line,about 20ft from the radio..i like to boost the signal somewhere in the middle,
rather than directly on the radio..
also the ATT will help to clear up some of the noise..
about the specific bands,not sure...
Yep..Got some radios..I can hear lotsa stuff...
