Topband: WTB: Guy wire stuff

** Which has never been denied by anyone in this discussion. OTOH linemen 
and other strand installers use it as a general description thus my tower 
ape terminology.

** As are the Big Grips rated at strand strength.

** PLP marketing is aimed at commercial and industrial applications and not 
hobbiests. Their idea of a radio tower starts where most ham versions let 
off.



> Every tower failure I have seen has come from incorrectly installed guy 
> strand, saddle clamps, or anchors. I've seen towers where people splice 
> guy lines with dead ends looped through dead ends!


** Ive even seen some with RatShak guy wire which is maybe 1/8. Ive never 
used an inline splice either.


 It's common to see someone
> worry enough to buy extra long grips (which doesn't do much for strength), 
>  > and then not worry about radius inside the loop (which just kills the 
> strength).


** Good points
