Heck, next time a T-storm rolls through, I'll record it ,
and let you hear it. Simple to do with my radio running
through the sound card. I can compress the file to
mp3 to save DL time. No unzipping required.

Now that we have heard all the benefits of various loop antennas, I
have a question about the physical part of the antenna. I am planning
on erecting an 80 meter or perhaps 160 meter square loop antenna. The
question is how have you fixed the corners of your loop antenna? Can
the antenna wire move in the insulator so as to equalize the force on
each side? Or is the insulator in the corner fastened tightly to the
antenna wire? Also, what type of insulators are your using in the
corners? Ceramic compression? Glass, Other type ceramic? Anyone using
plastic insulators?

Hi Paul, Make the loop out of insulated stranded #14 wire from Home
Depot, Lowes ect.. The corners can be of UV resistant rope with a loop
in it. The wire will slide in the rope loop. Should handle a KW and
stay up a long time. Don't need glass, ceramic or any other type
insulator.

Ceramic electric fence insulators are ideal for loop corners.

Paul,
It really doesn't matter to much how you prepare or fix the corners. I
have used free floating and fastened down tight. If they are in the trees
sooner of later the wire will snap regardless of how you have the corners
prepared. The alpha-delta cin insulator from Radio Works $1.50 are very good
one to consider using.

Hi Paul and the group,

I let my corners float and all I use are pvc 1/2 or 3/4 pipe 90 deg. elbows
with dacron rope tied to around them then flug over a tree. Been using this
method for years. No pulleys or extra fancy methods just rope and a elbow,
this way I can move the antenna around if I choose to change my feed point
at any time. Also allows for the stresses to even themselves out between the
trees depending on how the wind blows. Although one tree is a very small
sapling that stands about 40 feet high and the other three trees can pull it
via the antenna wire with no great effort at all. Also have enough slack in
the antenna to allow for rapid wind changes.
Everyone has a different method and most are very good and serve the purpose
they were intended to, one persons idea may not work in another area, but to
each his own method works otherwise there would be a lot of trial and error
going on, hi hi. Been there done that and got the hat to show for it to.
I'm fortunate in my area as I don't get much wind at all, although I have
used a similar method on the west coast of Vancouver Island with weighted
milk jugs instead of tying off the support line for two of the four support
lines.

I just heard Ray Price sing "For the Good Times" on KKYX, San Antonio,
680 KHz. The station is 200 miles from here. The sntenna is the built-in
loopstick in the radio. I listen 24 hours, all country msic, all the
time for more thann 32 years.

Best regards, Richard Harrison, KB5WZI
