[UK-CONTEST] O/H Heliax

[Ken Eastty]

I'm aware of at least one antenna installation which used a number of 
long o/h runs of semi-rigid co-ax supported on a wire catenaries. The 
cable used was Cellflex from RFS (half the price of the equivalent 
Andrews LDF4/50). Black UV resistant tie wraps (from RS?) were used to 
attach the cable to the catenary.
Last time I heard none of the cables had broken or fallen down although 
I'm now no longer in a position to know.
 From what I've seen looking through the fences (anorak mode on!)at 
Cellphone base station installations Cellflex seems to be a popular 
choice, there must be many reel ends of this cable around somewhere if 
not I believe that RFS may supply short lengths.
