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.
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.
