We may be into another  "Apples Vs Oranges" debate here

> FORCE 12: C3, C3S, C3SS  versus Tennadyne: T-6, T-8 and T-10?

If we're into similar boom length comparisons, it should be C3S Vs. T6, and
C3 Vs. T8. The T10 has a 24 foot boom

Since Force 12's in CA, and Tennadyne's in TX, that may be tough to do
(unless they just show you a computer pattern). Actually, that's a good way
for you to get a couple free antennas. Almost as good a way as having a
DXpedition (hehehehehe) ;) ;)

Which is going to cause a problem in comparisons unless Tennadyne has 74
foot towers in the same sort of environment as Force 12.

Since I suspect both antennas are going to be within a dB or 2 of each
other, things like environment are really going to make a difference here.
The advantages of one environment over the other just may be worth that 2
dB.

We need someone UNBIASED to make the comparisons in the SAME ENVIRONMENT on
the SAME TOWER, repeat them OVER TIME, against some sort of FIXED CONTROL
and post it here.
