For what it's worth, I like having both HT and hard mount in the truck.
The hard mount seems to be pretty powerful, I heard Nakman on the connection the other day and I was almost to Buena Vista.
I like having the HT, for when I get out of the truck so that I am still connected.
With that said, that does not really help your antenna question. I am also curious what is the best antenna solution, so that I can have that option for another rig.
