Dear Pat:
As John has indicated, you will be much more satisfied with a LPDA
than a tri-bander. Tennadyne has an LPDA for all sorts of lots.
However, be sure to ask for the extra sleeve option for the rear
(longest) element. You should use a good truss made of "plastic" rope
to help the boom load (use more rope than what is shipped with their
antenna) - in other words, have a mast that extends more than 1.5 feet
above the boom.
The elements are well designed mechanically, but will not take
really high wind and only about 5 to 7 mm of ice. (With that amount of
ice, the element ends point almost straight down.) I wish that one
could easily blacken Al after assembly so that the sun could help melt
ice.
Try hard to mount at least one wave length high at 20 m. - as John
has noted.
Use a piece of flooded coax to connect to the front of the antenna
that you run back under the boom to a coil on a plastic tube mounted
right across the (insulated) boom to mast clamp (terminated in a coax
connector that you can weatherproof and to which you connect the main
transmission line). Do not put the choke out at the end of the boom.
Let us know what you do.

I have the T6 and I like it very much. It meets all the specifications
and
works very well for me. If I was to do it over again, I would get the
next
bigger one as the SWR curves are a bit lower and the beam width a bit
sharper. But the T6 will beat the beans out of any small tribander in
all
ways except front to back.
Be aware that the minimum height is 40' with something around 65'
optimal.
Also Tennadyne almost always have them in stock for rapid shipment
unlike
other companies that can make you wait weeks or more for them to ship.
So for one more not very meaningful testimonial, I've worked 276
countries
in 2 years, with 100+ countries on 20, 15, 10m and I'm waiting
(hoping) for
cards on 17 and 12m.
