Thanks, Mike. I noticed Jack VE3EED made his calculations using the band
center. Out of curiosity I just write a little C program that uses band edges
and converts them to half wavelengths. I plotted the overlapping "red zones"
and, if I didn't make a mistake, came up with slightly different saf

At Field Day, just playing around, we used the KXAT3 to match a 20-
meter 2-element beam (fed with coax) on 80-6 meters. Not efficient on
any bands but 30/20/17, but ni
Thanks, Don. I have a 400' reel of The Wireman's #543 to cut up, so this looks
like a good place to start. Should be east to launch as well.

Scott, for years my main shack antenna was a wire running out the window to
a tree in my yard, a total of 200 feet. It is fed by a unun which in turn
is fed by about 25' of coax. The u
Gary and all,
That length is close to the W3EDP antenna length - as I recall, it is 86
feet for the radiator and 17 feet for the counterpoise wire. 80 through
10 meters is good, and the KX3 tuner will match it easily.

No, but in general, more is better, and it's better if it's not laying
on the ground. It simply becomes the other half of the antenna that
you're loading -- think of it as providing a ret

Hi Scott,
Any indoor (or laying on the roof) antenna is going to pick up lots of noise
from all the electrical stuff in the house. What you want to do will have a
unique solution depending on just what your physical environment is, so what
has worked for someone else may or may not work well for
Scott, if you want the magic antenna that is easy to build, easy to install and
cheap, give up now. Any conductor will radiate to some extent and the
excellent antenna tuner in the K3 will load almost anything but there are
reasons why contesters buy acres of land and spend tens of thousand or
Thanks everyone for setting me straight... In this case, 'random'
truly means random... In the 10 years I have been away from Ham Radio
I have become, well, less than fluent with antennas. hihi.
So, using the K3/100 with the built in AT, how would you construct an
antenna using a short piece of co

Hello everyone.
I've seen a lot of traffic on the "random wire" topic. Does anyone
have a link to a website or an excellent design for a "random wire"
that will at least do all bands 40m up (40-10)? Please drop me an
email if you have any information on a good wire design.
Thanks,

I would be in real trouble if I could not use wire antennas. All of my
antennas are in my attic. They consist of a full wave 40M loop fed thru the
little Elecraft balun via a short run of 450 ohm ladder line, a 65' marconi
(end fed "random" wire) in an "inverted U" configuration fed thru

Jeff,
The KXAT3 has a very wide tuning range and is specifically designed
for use with random-length antennas. Typically any wire longer than
20' or so can be tuned up on 40-6 meters. A 74-foot antenna will
probably be tunable to reasonable SWR on 160-6.
A random wire antenna can work very
