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. Zak Lau W1VT ARRL Senior Lab Engineer |

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. Zak W1VT ARRL Senior Lab Engineer |
