I have some (150'???) of Heliax that came from a cellular tower that was
dismantled. I had 4 connectors but not sure what happened to them. Not
sure of the size but this stuff is really big. It measures 2 inches in
diameter overall. I have been trying to give it away for a couple years.
If anybody wants it is free for the taking.
