The most important question for you is: What kind of a ground system do you
have.?.?.?.?.

Sorry guys,
This message got sent out again from an email address which has been
inactive for 6 months. The hot.rr.com address has been disabled since I
moved 6 months ago and has not sent out a single email. I guess last night
it decided to come back to life and send out emails. What is really weird
is that I subscribed to this site under my present email address and not
that one. So I don't have a clue how my old email address even got a hold
of this message, much less sent it out. I'm getting too old to try and
figure this stuff out, hi.
Anyway, while I have your attention (maybe) I have the Hy Tower up with the
MK-160. The swr on 160 dips at about 2.0 swr. Is that about as low as I
can expect? Also, as an interesting side note, I have about a 1.5 on 17
meters without the 17 meter add on. Also, about a 1.4 on 6 meters. The swr
on 80 is lowest at 4.00 MHZ and is dipping in that direction indicating that
my resonant frequency is above 4.00 Mhz. Can I just lengthen the top main
vertical section to bring the 80 meter frequency down without affecting the
other band's swr? I would like to have a good swr on 3.795, but it is
currently above 3.0. Also, is it possible to add a homebrew coil at the
base to widen the 80 meter band to the CW portion in colaboration to having
the MK-160 on the tower simultaneously? Is there a way to build the coil in
a manner that would allow 1500 watts rather than the 300 watts that is
offered by the Hy Gain coil (the LC-160W)?
I think that once I get everything t uned up it will be a good system.
Thanks,
Brad
