If you participated in last weekend's Phone North American QSO Party (NAQP),
please send me your results (QSO, Mult, Score, Team Name) to ka9fox@aol.com.
Note: if you reported your score on 3830 after the contest or if you posted
your score to the reflector already, please still let me know your team name
so I can try to compile team results again as well.

Had a bad cold, hope I didn't sound too bad.
10 was open great for the three hours preceding the contest.
A glimpse of the future, stuck on 20m all day (yuck). Oh well, as our contest
reflector owner would put it: There's no meters like 20 meters.....

Subject: Open Wire for Low Loss ?
Message-ID: <9408221424.AA12111@drmail.dr.att.com>
Has anyone tried using open wire line as as substitute for hard line or
heliax for long feedline runs ? On the surface, open wire looks awfully
good for loss, even compared to 7/8" heliax.
It seems feasible to run coax from the shack to outdoors, a 1:9 balun to
450 ohm line, a long run of 450 ohm line to the tower, a 9:1 balun back to
coax, and coax up the tower. A low-loss balun should be achievable - we are
not talking about high SWR on the open wire line.
What are the loss characteristics of the so-called "ladder line" that is
now being sold as psuedo-open-wire line ? How does it compare to true
open wire line ?
I have the potential for running about 300 feet of "open wire" supported
on insulated posts, in the clear (i.e. no trees or other conductive or
dielectric objects). By the time I get to the top of the tower, we're talking
about a 420 foot run.

Message-ID: <199408221540.AA06392@pobox.mot.com>
Well, I wonder how many people broke the rules this year?
Good thing I read the 1994 NAQP rules in NCJ before the start of the contest.
The power level now reads:
100 WATTS!! (No longer 150)
So, no advantage could be gained by owners/users of FT-1000's or IC-765's.
Ok, fess up....who used 150 (or more) ?
This rule should re-interest those opposed to the 150W rule.

Here are the results from the first time NAQP effort at KF0DJ.

This was the first contest to really use the new FT-1000D and it worked better
than the operator did. The 2el 40M and 4el 20M beams worked well, and the
inverted vee on 80 did OK. S9+20 static on 160 made WB5VZL the only signal I
heard on that band. The dummy lo... ah, vertical once again proved its
worthlessness on 10 and 15. Gotta get something up that works for those bands
to take advantage of the miniscule openings when they come.
Strays:
Larry, Larry, everywhere.
Kudos to the guy running 4.5 watts on 40. As strong as anyone.
And where were WY, NE, and ME anyway?

Steve,
Almost every shortwave broadcaster in the world uses open wire
feed for runs to the antennas. I just returned from a trip to
the VOA sites in SV, CN, A2 and S9. Miles of 4 wire 300 ohm line
going to huge curtain arrays pointed everywhere... fed with at
least 250kW.
When I lived in East Tennessee, a friend used ladder line to his
antennas. He lived in a real hole but owned the hill behind about
800 feet away. He supported it on trees and pressure treated 12'
2x4s using cheap ceramic electric fence standoffs. Don't run it
flat - twist it a few times between supports to maintain balance
and prevent flapping in the wind. Only maintenance problem was
occasional falling branches from ice/snow storms. The kind of
"snow" you get in TN is not available in CO. Rotator cable was a
major expense.
Low loss 9:1 baluns are a snap: 5 to 10 trifilar turns of #18ga
Teflon wire on a 3" ferrite core in a suitable enclosure. As you
said, its a low swr environment. Build two at a time and test
them back to back into a 50 ohm D/L.
How does ladderline compare to true open wire line? Very well. It is
within .1dB/100' of true 450ohm open wire at 30 MHz. And it certainly is
cheaper and easier than building your own. It is also easy to set up an
experiment on the ladder line - to test out the system before you commit
to it....
Regardless of where you get your hard-line, by the time you put
connectors on the ends, your investment is too high - unless you
already have cubic dollars and no children.

Just received my Sept CQ and can't find my call in the results. I
operated Single Op Assisted and score was 1.06 meg. Am I missing

Before any nasty comments from me, any comments from EST or AR (or

I would be concerned about degrading the nulls of directional antennas in
the receive mode by using open wire line. I don't think the achievable real
world cancellation/shielding is nearly as good as coax.

I got alot of responses to my question regarding radials and shunt fed
towers. I have compiled the responses and will email it to anyone that is
interested. It's very interesting reading for those interested in this
subject. Just send me an email with something saying "ya I want it" and it
will be yours.
Sure liked K4XU's response to N2IC's question on open wire feeders. Now
that is why I stay subscribed to this forum! Well, that and I found a mail
program that will automatically trash mail from anyone I add to the list!
The list is growing!
