The most popular amateur bands on vehicles are 2M (VHF) and 70cm (UHF). CB radio is 11 M so it's a HF frequency but just barely. Building an antenna that covers that many bands is difficult.
I have an adjustable fiberglass stick that can be adjusted for CB and 11 meter amateur radio.
It's best to go with two separate antennas. I have separate amateur radio antennas for around town and out on the trail.
I use a detachable ham radio unit....
That is a sick set up Paul!! Really like the hardware under the seat idea - seen it done with a compressor, never thought of it for the HAM set up. Awesome explanation & photos - thanks so much!
I have both CB and HAM in my primary rig. I'm a member of several off road clubs and there's a large transition from CB to HAM over the last 1.5 years. I've seen CB become the secondary from of communication.
I have a both hand held HAM and mobile HAM unit in my rig. The handheld works much better than my hard mounted CB with external antenna.
Thanks for the input BFE - HAM is definitely the more capable method. I've heard CB is more popular for runs so it is interesting / intriguing that you have seen groups switching. I also definitely want the HAM because we camp a lot, and communicating with someone who is an hour behind is much easier with a long range HAM set up.
Almost any Ham will beat CB for performance, but most of the chatter for this group is still on CB. Plus on CB you can still say stuff like "breaker breaker good buddy, you got your ears on the flip flop, I got a sum-bich meltin my antenner"
This is half the reason I want a CB, Randy - so we can talk like truckers whilst conquering trails.
