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 the following advise: * The ONLY means of achieving the required degree of Isolation is to use the Isolation Transformer as specified by K2AV * Tests using 1:1 Baluns and Line Isolators have ALL FAILED - you waste RF Power, Time and Money unless the specified xfmr is installed * DO NOT attempt to use Insulated Window Line for the FCP - We already tried it and it does not work - too lossy * Use #12 Bare wire for the FCP elements - Moisture gathers on insulated wire and detunes the FCP * Use 4" spacing between FCP elements * Small diameter PVC Pipe Spreaders work well - use caps on both ends and put a small weep hole in the bottom cap * It is best to install the FCP in a straight line the overall length is 66' if bends are necessary make them near the ends of the elements 73, Jack W0UCE _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
