[TowerTalk] Radial losses - was copper thefts

[K8RI on TowerTalk]

As far as normal ground resistance I'd really not expect to see much 
difference. OTOH I'd be concerned about diode action and noise from the 
barbs in some conditions.  The barbs are just a short piece of wire pointed 
on both ends that is wound between the two main steel strands. The only 
thing holding the barb is the twist plus a slight kink in the barb itself. 
One other thing. I'd sure hate to catch one with the lawn mower. IF it 
didn't get you while winding it up it'd still be a lot of fun getting out 
from under the mower deck. <:-))  OTOH, steel electric fence wire is 
relatively inexpensive and I'd bet it'd do a pretty good job even if it had 
to be replaced every few years in some locations.
