Hello, Group..
Ray N6HE here.
FYI, there's a QST article by Joel Hallas W1ZR describing a two-radial
ground plane for 20M and 15M built using ladder line for the three elements
(one radiator and two radials). I scaled it back for 17M/12M dimensions and
it worked great. We use it on our Palos Verdes ARC mini-DXpeditions to
Catalina Island. I believe it was published in mid-2013? He also had a
follow-up article with dimensions for other band combinations about a year
later.
It's super cheap, coils up to almost fit in half a shoe box if you want to
use it portable. I'd put a Common Mode Choke at its base.
If this is something that you'd like me to follow up on and get the exact
info, let me know and I'll dig it up.
73,
Ray N6HE

Subject: [TowerTalk] Any 17/12-Meter Vertical Antenna available?

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.
