The way my XFMR is mounted in the enclosure I can't take a decent photo of
it. I have asked Guy to provide a photo of his installed xfmr or a photo of
one not yet installed. When I receive the photos I'll post them on the

An actual pic of this transformer would be worth a thousand words. The
drawings are great but I'd love to see this thing wound and connected for
real. I don't have any experience with such things so having a pic to show
details of how it works when drawings meet reality is priceless.
Thanks for al
I dont know what kind of an isolatuion transformer you guys are using, i
come from a vintage view point where no ferrite or coax is ever used
except to go from the transmitter final coil to the antenna coil.
coupling is just some #14 insulated wire around the whatever coil i am
going from to a wii
No need to dig up existing stuff to keep from affecting the FCP. Deal
with existing radials according to your needs and common sense. They might
help some, though there certainly is no proof of that. If you can't see
'em and aren't tripping on them, why bother to mess with them. 73, Guy.

Steve:
As long as you keep the middle 20 feet (10' on either side of the center
feed point) in a straight line for cancellation purposes, you can put the
remainder in the shape of a V or bend as necessary.

Im currently one of those ' Limited Space 160 Ops' .. @ moment im using an
'Inv L' to use the term loosley. ( Diagram Attached )
I am really thinking about trying one of these FCP's.. altho it would take
some considerable work removing whats already in place.. but no big deal.
My question is this
We built and tested a window line FCP - when it was dry and wet... it was a
dismal failure.
Been there, done that and I have three lengths of window line cut and
connected together in a 33, 66, 66 section globs in my storage shed. It is
available immediately to the highest bidder, shipping
Just a word on ferrite beads, and other kinds of baluns. Trust us, if it
could be done wrong, we blew it, if it could burn, we burned it, if it
could be cracked, we shattered it, if it couldn't stand up to 1.5 kw, we
smoked it. We tried every possible short cut and cheep trick imaginable.
Anythin
>sense. It is well known that window line is >lossy when wet.
I am curious if anyone has actually measured this over a range of frequencies.
Afaik, the "it's lossy when wet" is based on a model that I've seen some say
overstates the loss for a wet window line.

Don't waste your money, time and effort trying ferrite beads, baluns, line
isolators or anything EXCEPT the Isolation Transformer...

Thanks for posting the drawing.
What is the projected power handling capability of the described feed

That's interesting, because of an argument presented

In response to my posting, Per SM2LIY commented that the polar path at higher
solar activity does not work good on topband.
He is corret, and I should have added that qualifier.

New information, details and drawings for the K2AV 160m Folded Counterpoise
(FCP) System, Isolation Transformer and Installation Notes have been posted
on my website.
http://www.w0uce.net/K2AVantennas.html
If you are interested in building an FCP versus putting in a dense radial
field heed
when every contact is important as when you run 160m QRP the "N6RO
approved method" is the best
MY GOD!!!
if N6RO approved it, why isn't every one doing it??
mike w7dra, who always sends "N6RO approved" we should get a sticker
saying this like the ones you see on QSL cards

Topbander enthusiasts,
On Dec 5 Brian VE7JKZ asked about solar flux in relation to 160-Meter
propagation and wondered about solar min versus solar max.
On Dec 6 Bob W7RH wondered if anyone has looked at space weather data with
respect to propagation during ARRL 160.
Also on Dec 6, George W8UVZ
Guy--
Thanks-- beautifully described. It is as I thought, but the diagram on the
W0UCE page confused me, particularly with the connections to the
Counterpoise.
