Thanks all! My google skills were poor today! It is definitely the
HB34D. I might actually give it a shot. The specs say it weighs 18kb
or 40lbs.......I didn't eat my Wheaties this AM but it did not feel
anything close to that weight. My other choice is a F12 original C3.
I have to watch the weight and wind loading.
Once again thanks all for the very helpful emails!

Hi Mike,
I found this online (scroll to the bottom left for old TET brochures
and manuals):

IIRC the OSU ARC, W8LT, had a TET 15/10 meter dual band Yagi back in
the mid-to-late '80s when I was a member. It was interlaced with a
two-element 20 meter quad. We eventually took down the dual-bander and
added a third element to the quad and strung the spreaders so that the
quad had three elements on 10 and 15 meters. Our tower (a few
sections of Rohn 25) was nestled between two large flag poles on top
of the southeast bell tower at the OSU football stadium. This limited
the turning radius such that you could not have full 360 degree
rotation of a 20 meter Yagi (hence the 2 element quad). I think the
TET 10/15 meter dual-bander fit within the turning radius. The 20
meter two-element quad definitely fit within the available space, but
barely. When we rotated the antenna, the VSWR would swing wildly as
the quad elements came in close proximity to the metal flag poles. I
think the boom of the quad was at around 110 feet above the parking
lot of the stadium, although that whole area was close to the
Olentangy River, so it was in a bit of a low spot terrain wise.
Nevertheless, that quad antenna worked pretty well.
Another former OSU ARC member, N8SM (now sadly an silent key) might
have had a TET tribander on the repurposed TV tower at his parents house.

On the tower I just bought was a TET 4 element antenna. It appears
to use a dual driven element and then a two directors. It appears
that one of the directors is for 10m. Traps are small so I don't
think it can handle legal power. This was probably purchased in the
90's. Does anyone have a clue what it might be.
The coax on the tower was awful. The jacket was cracked all over.
No clue what the brand etc. It is a crank over tower. I was shocked
that the coax was never replaced.
