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
