Since the 1970's Phillystran products have been supplied to the global broadcasting industry. Our synthetic antenna guys have been in use on some antennae for over 40 years. Phillystran is a proud member of the National Organization of Tower Engineers (NATE).
Phillystran High Performance Tower Guys (HPTG-I) are made from stranded aramid fibers with up to 1.7 million pounds breaking strength. HPTG-I aramid fiber guying systems are the result of many years of experience with AM, FM, TV and communications towers up to 2,000 feet high, operating at powers as high as 2 megawatts. HPTG-I is in use in every climate from the deserts of Saudi Arabia to the tundra regions of Greenland. Phillystran HPTG-I guy assemblies are installed atop One World Trade Center (Freedom Tower) to support the 400 ft mast. The structure is the tallest in the Western Hemisphere and is home to a wide variety of broadcast and communications antennas serving the great New York City area. In San Francisco, the famous Sutro tower relies on Phillystran HPTG-I tower guys to support the three stacks atop the tower with the many TV and radio antennas. The Sutro Tower is a 977 ft three-legged tower located 834ft above sea level.
