Hi
Kevan,
I’m
sorry but I don’t think I get the connection between a NVIS antenna and
my station as it is?
At
the present time I have two 40m EDZ antennas, one pointed toward Eu and the
second on pointed toward JA. In addition, I have a two element 20 m EDZ yagi
pointed into Eu. At the present time I am in the planning stages on a 70’
tower with an OptiBeam 2-el 40m yagi and a 16-el tri-bander. How does a NVIS
fit into this scheme? I seem to be missing your point Kevan?
73,
Tom

Hello Tom,
I'm not in your same situation, but would suggest considering a low
horizontal loop for close in stations. It gives a very good NVIS signal which
it seems to me would help you into Tennessee. I've
suggested the loop to the local ham club and a two people (that
I know of) have put them up and are happy with their coverage in SC, GA
and NC. They also make DX contacts on them and I've heard a couple
others intend to put them up since we're all having good luck with it. I use a
272 ft loop up 20 to 25 ft and feed it with about a 50 ft run of bury
flex coax to a DX Engineering 4:1 Balun. I have good SWR at some
point on 80, 40, 20, 15, and 10. A tuner gives full band coverage on
all those bands. I first fed it directly with coax and wasn't happy. Many
choose to feed it with ladder line to cut their feed line loss, but I
didn't want to deal with the lightening protection and wall
penetration issues of ladder line. You can read about the low loop
either on line or in the ARRL Antenna books. It's often called a Loop
Skywire.
This is completely anecdotal but in 2006, shortly after
changing to the 4:1 balun, I entered the SC QSO party and took first place
in the state. I overheard several stations talking about me. They hadn't
heard me on the air before and did not believe I was only running a 100 watts
because of how loud I was. They were comparing me to other stations in my
general area which was about 150 to 180 miles from them. They
weren't very aggressive contesters, focused almost exclusively on working SC
stations, and since I took advantage of the Salmon Run
stations from Washington State to both give and get
points for the two contests it wasn't too surprising an inexperienced
contester such as myself was able to get a plaque. Never entered again
though, I don't much care for it.
If you have the room, give the loop a shot. It might
help.
