We completed our 100 ft Rohn 55G Tower today! Matt at XX Towers got the second Star Guy Bracket from Rohn, installed it on the top section of the tower and raised the top section into place. After he and Andrew attached the second level of Phillystran guy lines at the 95 ft level, our tower was up.
Matt placed our 21 ft x 3″ mast inside the tower at the base prior to installing the top section of the tower. This makes getting the mast into place when the rotator goes in much easier!
Matt also finished the guy equalizer plates and grounded them. Here’s what they look like.
As you can see, the Phillystran guy material transitions to Extra High-strength Steel (EHS) guy cable near the ground for safety reasons. Here’s a picture of a portion of one of the Phillystran guy lines on the ground. You can see the transition to the EHS cable at the end.
The Star Guy system worked out great and should keep the tower from twisting under the torque of rotating two large SteppIR DB36 antennas at the same time.
The tower base is also grounded at this point. We will be adding two additional ground rods on the other two legs and bonding the tower ground to the station ground over the next few days.
We are really happy with the results of our tower project to date. Now we need to get some antennas on our new tower! We are expecting our SteppIR antennas to arrive soon – it sure is tough to wait!
