Hello Paul - I was at Bill's (K4XS) today, selecting Rohn 55 tower sections and hardware for my site in Colorado. However, he didn't have the 5/16" Polyrad guy cable I need. He said the standard spool is 1200 ft. That would be perfect for me. Do you know of a source? Please respond to the ah3c address above. BTW your web page blew me away!!! 73, Pete W0RTT
