[BC] about STL dishes and jumpers

Ya know, this is generally because someone either doesn't know how to  
read, OR KNOWS BETTER THAN THE MANUFACTURER!

In general, you need hoisting grips every 200 feet,  You need a  
grounding kit at the top and the bottom, and every 200 feet.

You need to use either round member adapters or angle member adapters  
AND PROPER CABLE CLAMPS.  It depends on the cable diameter, but ever  
three to four feet.  Because of tower members, they often need to be  
used much closer together.  Of course, there are "clip in" mounts, if  
the tower is designed for them, or someone has installed "banjo  
mounts" on the tower (which are quite nice).

For at least the last 20 years I have been specifying transmission  
line ladders on all the towers I have built.  For large diameter  
lines, the ladder is a place to bolt in the cable clamp.  For smaller  
cables, snap in cable clamps are easy and fast.  I specify two ladders  
back to back for the snap in clamps.  You can bolt two clamps into the  
same hole on opposite sides, but not the snap in clamps.

if you are gong to use Wrap-Lock or #12 solid twisted copper instead  
of the proper mounts, you deserve what you get.  Sure, it will last a  
few years, but it won't last.
