Hey Jim,
I use the polyester black rope (white inside). This stuff is great and a great
deal cheaper than Phillystran. The 5/16 stuff is rated at over 1700 lbs tensile
strength! I have three guys on a 54 foot tower. The tower is bracketed to the
house at 20 feet and the guys attach at 50 feet. The stuff is easy to use and I
use standard heavy duty turn-buckles and cable clamps. Put it up and tighten it
up, After a few weeks repeat the tightening process as it will stretch a wee bit.
After that just forget about it! The cable clamps allow for easier tightening
adjustment vs direct tying. I've used 3/32" stuff to provide sag support on a 28
foot boom 2M SSB yagi. That rope has been installed for over 15 years and it's as
good as it was when put into the air. Considering the WX here in the upper
midwest I'd say it's good and safe stuff.
I had the same questions about this rope originally. After receiving an email
from a commercial tower installer who said he's used it for years on some pretty
big towers I'd say it has earned it's tower worthiness.

A bit of text from the webpage:
MILDEW & ABRASION RESISTANT, STRONG DOUBLE BRAID CONSTRUCTION, BLACK POLYESTER
JACKET FOR ULTRA-VIOLET PROTECTION & LONG LIFE, TIES EASILY, NO ADDITIONAL
HARDWARE REQUIRED.
One last note, when cut, the ends will fray. They sell heat cutters that will
melt the ends to close them off. I just use a lighter. It works fine and a Bic
from the local gas station is alot cheaper than the costly heat cutters. For your
situation the 3/16 rope would probably be all that is needed.

wall bracket it to my house at the 8 ft level and guy it. A flat base will be
anchored to the cement patio. The only load it will bear will be a 10 ft mast
with a 5 ft cross bar at the top (forming a "T") with pulleys and ropes to hoist
various wire antennas. Since the load is light and I'm trying to do this project
on the cheap, is there a less expensive alternative to Phillystran for the guying
that will do the job? Recommendations, including a good place to buy it, would be
appreciated.
