I like the one W3TLN has on his coach. Looks like it is a mast for 2m.
I am working on a HF vertical for mount on a coach, the ground plane is the issue for a good vertical. I am thinking a multi band dipole can be built and set up nicely just about anyplace, but height would be the issue on that one. Maybe I can put a crank-up 6 element yagi on the roof. (yeah the wife would go for that)
My problem is I am picky about asthetics. I don't want it to look like I made it in my garage. Even if I made it my garage.
