Gary,
I've had an X-9 with the X-940 40m add-on loaded dipole since it first went
into production. It replaced my KT-34XA, which I had for 15 years, and my 2
element full-sized 40m Yagi. Overall, I find the X-9 to be well
constructed, and a good performing antenna. The log-cell with the added
full-sized reflectors and one tri-band director of the X-7 is also a good
antenna. I probably agree with others that responded to your question that
the added full-sized 10m director and tri-band element that is added to the
X-7 to make the X-9 may not add a lot in performance. However, 1 dB can
make a difference sometimes. I really don't know if it is worth the extra
boom length and weight.
One feature that isn't advertised that I find very useful is that the X-9
covers 12m and 17m. It has considerably more gain than my 17m half-wave
sloper on 17m. On 12m I have nothing to compare it to but it is directive
with good f/b and f/s, which would lead me to believe there some gain, also.
The VSWR is quite low on both bands. I just check it to verify the VSWR
readings. It is 1.3:1 on 17m and pretty flat across the band, and 1.3:1 on
low end of 12m, and decreasing to about 1.1:1 at the high end. These
measurements are in shack with about 100 ft of coax. I assume that the X-7
should also work on 12m and 17m, but I really have no experience trying the
X-7 on those bands.
Overall, it has been a good performing antenna, and I'm very satisfied with
it mechanically. It can support about 200-300 birds with no sagging.
73, Bill

Hello TT
I would like to talk to someone who has the X-9 or X-7 up and pro/cons of
this antenna. What did it replace and are you satisfied with the
performance. Thanks in advance.
