All,
Still pondering the idea of purchasing a KT36XA by M2. I received a few e-mails
and would appreciate additional comments about it's performance before I make
the purchase.
I've been told that it is one of the better tri-band Yagi's because it uses all
of it's boom length when compared to some interlaced designs that use less than
the entire boom. The Optibeam OB16-3 does use most of it's 33 foot boom, but it
is a bit heavy and pricy. Element spacing for 20 meters on the Force12 XR31 is
about 24 feet.
LB (W4RNL) made the point that the gain figures quoted for this antenna (and
other tri-banders) are close to the maximum obtainable; even for monoband
Yagi's of similar boom length. So I would assume that like other tri-band
Yagi's, it falls somewhat short of true monoband performance due to the fixed
element spacing and loading.
With that said, has anyone been able to accurately model the KT36XA (especially
on 20 meters) with it's shorter elements and linear loading and compare it to
interlaced designs of the same boom length?
Being an M2 product it looks like a sold design, but does it's performance come
close to matching it's number of elements and size? How well does it model when
compared to a monobander on say 20 meters with the same boom length?
Thanks,
73 Tony KT2Q
