[VHFcontesting] coax for 50 and 144 questions

[David]

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.
