OK, I'm resigned to the fact that only a real CB antenna gives sufficient range on CB frequencies. Since I only want one antenna on my vehicle, I'm looking for suggestions on which CB antennas might make for decent scanning up through the 800MHz band (or at least UHF). The one clue I have so far is that a fatter antenna is supposed to provide wider band coverage, so I'm thinking that a fiberglass rod might be better than a metal whip. Load position and length might also matter, but I don't know exactly how. Any suggestions, ideas or experiences?
