[TowerTalk] Pretension an antenna.

[Roger (K8RI) on TT]

The one from the hardware store is far more rugged and can tension rope, 
Phillystran, EHS, and wire rope to many hundreds of pounds without 
cutting it
It works to over a 1000# on EHD and wire rope, but woks as well for 25 
to 50# on small rope and is easy to remove whether running 20# or 1000#, 
but is not a DIY device even though it's only 3 parts. OTOH I think I 
could make one out of Al with only a band saw, belt (or disk sander) and 
dill
