    Phillystran OD's are:

HPTG2100        0.17"   6mm 2100# beaking strength
HPTG4000        0.22"   8mm 4000# bs            3/16" EHS equivalent
HPTG6700        0.37"   9mm 6700# bs            1/4" EHS equivalent
HPTG11200   0.44"   11mm

    Well, you've got 3/16" EHS equivalent so as long as that what the Rohn 
drawings call for, knock yourself out.
