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/K2AVantenna
Thanks for posting the drawing. What is the projected power handling capability of the described feed transformer? 73 Charlie (Chas) N8RR _______________________________________________ UR RST IS ...
I haven't built this system, but the suggestions above make sense. I have been trying to encourage using transformers instead of baluns on 160 meters for years, but it's a tough sell to overcome the
Full Legal Limit has been used on my and K2AV's Inverted L Antennas with FCP and Isolation Transformers as described without any problems. Thanks for posting the drawing. What is the projected power
We appreciate your comments regarding FCP construction Rick. We have Guy, K2AV to thank - he is the developer, designer, engineer and I am fortunate to be his Field Trial "Guinea Pig" --Original Mess
I was thinking of sliding a whole bunch of ferrite beads over the coax feedline right at the end. But I'll take your word for it. This is all very interesting. I'd sure like to try Guy's invention my
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.
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
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 se
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
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 anten
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
Hi Guy, Many Thanks for you info. I plan to build the transformer. I am wondering how you housed the unit?? Thanks in advance for your input... 73, Ted K2QMF On Thu, 8 Dec 2011 22:46:47 -0500 Guy Oli
very interesting, the FCP is a way to allow the real estate challenged (no place for a true ground radial system, or a long high vertical antenna) to get something that will do more than just warm wo
Hullo folks. FWIW..... I mounted the FCP on my "inverted J" which is about 60 up, 40 over, and another 40 to 50 over again. About 150 feet of wire on the radiator. The FCP and transformer box are mou
Wonder if that FCP would be mo betta for my 43' vertical with three 25' top hat wires mounted in a NORD sort of configuration, angled down at about 45 degrees. I have 40 counterpoises- 25 are elevate
The FCP is a single band solution. You can use an existing antenna, instead of the "simple solution" tune and prune for resonance, but then you have to supply your own separate method of getting to r
