Larry,
There was a two band vertical in QST some years ago ... consisted of
a single vertical with an L-network designed to match both bands. I
think one of the follow up articles included info on 17/12 meters.
You could also build a 17 meter vertical using tubing then add a
plastic or PVC "spreader" to hold a couple 12 meter wires a foot
or so on either side to create a parallel vertical.
Check the QST archives on the ARRL web site if you are a member.

Kelly, not impossible, but not easily done, either, at my place. I'm hoping for
something like my Butternut vertical - something I can mount in a simple tripod
on the garage roof. That's why I'd like to find something like a simple,
aluminum 2-band vertical antenna for 17 and 12-Meters. No problem stringing out
radios for those bands, either - I already do it for the Butternut.

Hi Larry
What's the population of non-metallic supports like at your QTH? (Read: trees)
The ladder line vertical Ray mentioned might work very well, particularly if
you get it off the ground. You'd need two radials per band and a good choke
(eight turns of RG8x on a mix 31 Biggest Clamp-on would work), but you'd get
added efficiency by being away from the ground.

Yes, I'm interested a vertical only. No tower here at this QTH - if I had one,
I'd put my old 6-band quad back up.

Not sure if you're limiting your choice to verticals, if not there's this.

Does anyone know of a dual-band antenna that covers the 17 and 12-Meter bands?
I know there are many multi-band antenna versions available - the Hy-Gain
12AVQ, the Hustler BTV series, and others. I have a Butternut HF-6V that I've
added the 17 and 12-Meter kits to, but they just don't tune properly - this is
a well-documented problem with this antenna.
I'd be interested to know of a 17/12-Meter ONLY antenna that might be
available. I also know of the Cushcraft WARC-bands 30/17/12M rotatable dipole,
but I do already have good 30-Meter performance with the Butternut vertical.
Maybe someone has modified a 12AVQ or a similar multiband vertical antenna into
something that covers just 17 and 12-Meters? I'd like to have a separate
vertical antenna for just those two bands.
