Topband: K2AV 160m Folded Counterpoise Antenna - New DetailsPosted

[Guy Olinger K2AV]

No need to dig up existing stuff to keep from affecting the FCP.   Deal

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.
