Looking for the best out of the worst kind of antenna for my KX3 all band.
I think you just summed it up nicely yourself. These telescopic antennas
with loading coils at the bottom are all going to be many dB down from even
a modest wire antenna on a push up pole, like a Jackite kite pole.
Well Antenna theory and operation, like the rest of physics, always hold
true (nuclear blasts don't count)... so the more radiating surface (wire
length or tubing surface) you can get in the air... the better. There is
also a convenience factor, meaning whatever it is needs to tune for the band
Fred,
for many, my self included, as long a wire as high up in a tree as I can
get it, with a counterpoise about 50' long is my favorite.
The antenna wire up in the tree and going down to ground at the far end,
and to the rig (Via BNC to binder post adapter) is typically about 130'
in my
Look at the PAR end fed wire.
So convenient, well made, works like a CHAMP.
Use it with my own KX3.

I'll second that. I have the PAR 40/20/10 and it works great. Also good when
there are no trees around is the Buddistick. It works well up to and including
30m, but not so well on 40 with the original whip and coil.

I'm checking out each and every one of the antennas suggested a really good
mix. One question the Buddipole vs. Buddistick which is best and the main
performance issues between the 2 from those using them? The Par is very
interesting, I might be wishing for too much but the WARC bands would be

a tree isn't the ideal (like on some SOTA peak activations). For that,
The PAR works great on 40m, it's the Buddistick that is inefficient on that
band with the original coil and whip.
A magnetic loop isn't hard to build. You can get an air variable capacitor, say
100pF, some soft copper coil from the hardware store and PVC tubing for support
and build one in no
The par end fed z has served me well portable - used it for 2012 field day and
placed second in our class - although we did have a hex beam as well for
daytime operation - when 40 went long in the middle of the night - the par end
fed did great. I typically get into eastern Europe with the

Potentially lethal reminds me of one particular engineer I encountered back
when I managed haz waste site cleanups. He was deathly afraid of nackle.
Short exposure was known to be deadly to plant and animals, and worker exposure
limits were very short. Nackle, I had no clue until I

Hello,
I meant potentially lethal if you touch the loop while transmitting, as in
electrocution, not RF exposure…
But we are diverting from the Elecraft subject here...
