I'm just progressing from a 2M rig to a Yaesu FT857 which is HF, 2M & 70cm. The 2M&70cm is a separate antenna out, so that would be ok to use a dual band antenna I think, but what do most of you do for HF use? Do you keep a collection of antennas in the back and just swap them around which I have seen some users do, or do you use a screwdriver type adjustable load antenna - which are pretty huge by UK standards? I think I may end up driving around with a whip tuned for 14MHz and 28MHz in the back, and some kind of push up pole end fed antenna if I'm staying somewhere longer.- But would I probably need an ATU for that? Do you prefer a manual type matchbox or an electronic ATU? I see the competition field day folk seem to prefer the electronic black box atu's. Fitting and holes not a problem - it's a Landrover, but being an alloy roof I'll use the military side antenna mount.
