Multi-band antenna...
Here are a few pix of the antenna I currently use. Explanation at the end...

Detail of top of antenna...
This antenna is designed for use on four bands; 70 cm (440 mHz), 2m, 6m, and 10m/11m. The 10m/11m element is the uppermost section; the loading coil (black) and stinger (metal radiating whip above it) can be removed, and replaced with any one of a number of other coils/whips for whichever band you choose... 15m, 20m, 40m, etc.
The mount base can be rotated in two planes for fore-aft, and lateral adjustment, and the base itself is Cruiser-friendly (i.e., no holes to drill, no paint scars when you move it/remove it.
The intended use is to have CB/ham VHF/UHF all in a single antenna, and have it up in the air where it will do some good. I can use a VHF/UHF hand-held to "talk to the Cruiser" on 440, and the radio cross-bands the signal and retransmits on 2m to a local repeater on the same antenna. Most 2m repeaters can cover a 200 mile radius, so you can see the utility of this type of set up.
There is way more to this installation (HF SSB, digital email over the radio, etc.) that I'm still working on, but even this part alone is probably overkill unless you want to get into it... Anyway, just a glimpse of what can be done.

PS: A final thought... if the repeater you are communicating with in this example is "linked," that is tied in to the IRLP (Internet Radio Linking Project), then your signal from that hand-held can be "retransmitted" yet again anywhere in the world where there is another linked repeater. You can even make phone calls... as I have said before, the possibilities are endless.
