I got a 'DEAL' on a Icom AH-2B antenna and a AH-4 tuner. I spent days making a quality installation on a 1973 Land Rover that gets beat here in the mountains and on the ranch.
I eventually got hold of the literature and now find that using it with my IC-7200 I won't be able to get into the 80M band without at least 23 ft. of antenna.
I called ICOM and it was suggested a 20M hamstick would work. I am looking for other possibilities, like a 23 ft. long vertical for this base?
The above equipment is all ready mounted, i haven't even used it yet and I would much prefer finding a way to make it function, especially because of the arduous environment it survives in and the extreme effort it took to get it on this rig. Any ideas?

If you are parked you may be able to add an extension wire between the vertical and a tall support, such as a convenient tree.

yea, it seems that is gonna be the case. a 23' tall vertical is very $$! and would not be accomodated well on this vehicle. I've heard of other matching units that may work but i suppose the swr reflected and such may be a bit much ..............
Thx.

Humvees usually have antennas mounted on the rear of the antenna and bent over in a half loop towards the front of the vehicle. A vertical has a null overhead, which can prevent you from taking advantage of short skip on 80M.
