That looks like the best option. I wont be operating anything while riding. I would need to have this or one like it mounted to the handelbars. How would I hear someone calling me though??
Only thing I can think of is an earbud. Should have a 3.5 on it. You could have the handheld in a backpack or rear bag.
Edit: Or tank bag. Backpack would probably be the best, in case you get tossed!
Gary, a mag mount antenna is good for temporary use. I have a Wilson 1000, but it’s tall. I hear good things about the Wilson Lil Wil.
If you’re going to leave the CB in (which is good, and sometimes required on group or club trail adventures), I would mount a permanent antenna.
