With help from Frank (Annie’s Father), and Ted’s (Authority Tree Service) bucket lift, the Universal tower has been raised. On top, the hex beam (6, 10, 12, 17, 15 and 20 meters), below, two Comet VHF/UHF verticals.
The assembled tower before antenna installation
The hex beam was assembled on the ground and attached to the mast. Stand off brackets were bolted to the tower and VHF/UHF antennas were installed. The rotor cable was run into the shack and tested.
The bucket truck arrived and the key was getting the bucket up to about 70ft above the tower base. We attached a pulley at bucket height and a rope to the tower, and slowly raised it to vertical!
The tower in place and ready. Now working on grounding systems and coax runs.
My first tower installation at the K2ADA Radio Ranch. The Universal 21-50 is an aluminum 50 ft tower rated at 21 sq ft of wind load. It is self supporting, and requires a substantial base of concrete: 5’x5’x6′. The hole was dug by hand, no , not by me. Caruthers concrete dug the hole and provided the forms and concrete – lots of it. Here are some photos of the hole, steel base and the first tower section.
6 ft deep! A ladder was the only way out!
6 cubic yards of concrete.
Universal 21-50 first section installed.
The tower has arrived (Universal 21-50), and the main multi band HF antenna is on order. After much consideration and research, I ordered the KIO Broadband Hexagonal Beam. 6 bands, one feed line and twenty pounds. I really considered a Mosley TA-54-XLN-6 and, one day, I may still end up with one. I’ve sized the tower (21 sqft wind load) and rotor (hy-gain IV with up to 15 sqft of wind load) to turn a much larger antenna than the hex beam. The TA-54 has a 21ft boom, longest element 30ft, and weighs 87 lbs. It’s a bit of a beast. Of course there is a big difference in gain: 4 elements compared to 2, but I like the light wind load of the hex and it will make the raising of the tower much less of an adventure.
The tower will also support two Comet GP-3 VHF/UHF ground planes and the surrounding trees will support a Buckmaster 7 Band OCF Dipole and an Alpha Delta 80/40 inverted V Dipole.
