>>> Hi Guys,
>>>    Looking for advise on how to terminate Phillystran HPTG 1200I small diameter 3/32" guy cable for maximum strength?  Instructions say to use 3/32" cable clamps and I've tried that but the small diameter Phillystran squashes down so small the cable strength is greatly weakened.  Perhaps I'm tightening the cable clamps too tight?  If so, there appears to be a real fine balance between getting the clamps tight enough to hold but not too tight to squash the cable and weaken it. Can anyone shed light on how to properly tighten the cable clamps for maximum cable strength on this small 3/32" diameter Phillystran? Thanks & 73!  Dick- K9OM  (RLVZ at aol.com)
