[TowerTalk] Mosley Antenna Question

[john at kk9a.com]

That is surprising since the C3 has an 18' boom and uses only a portion of
it on each band and the TH7 has a 24' boom and uses most of it.  I had not
read the K7LXC/N0AX report and did not know this. I was a guest op and the
TH7 (with a BN-86 balun) was not my antenna. I did unscientifically
compare it to a 4el SteppIR and saw little difference. Given the smaller
size and lack of problematic traps, I would prefer the C3 if the
performance was equal or better. My Aruba station had a 4el homebrew 20m
beam on a 36' boom which seemed to work well.

The TH7 is not a bad antenna, I find it difficult to believe that a C3 out
performs it.  I had the world high 20m score in the last WPX CW using a
Hy-Gain TH7DXX

##  sadly to say, yes indeed, a C3 will outperform a TH7-DXX.  K7LXC already
ran that test.
N6BT ran the test as well, using a spectrum analyzer at the RX end, with
SA set
to 2db per division.



##  A C3 is like 4.1 dbd....and your TH7-DXX is less than that.    The sa or
audio gear just reads it as..
X on ant #1..... and   + /-  X  on  ant #2.

## Compare a C3  with a Mosley  TA-33jr in the above format....and the
results
will make u gag.  Gets
even worse when a TA-32jr is used.
