Features
About our Tower
I put up a Hy-Gain HG-52SS 52 foot crank-up, self-supporting tower. For stability and safety I added heavy duty wall bracket to connect the tower to our shop at nine feet, and guyed it three places from the top of the tower. I added two small 2500lb 12VDC winches. One to raise it up and down and another to tilt it over for upgrades and repair. The power for the winches comes from a battery in the shop. I have an 125ft underground PVC conduit from my radio room to the Single Point Ground Panel box on the shop next to where the tower is located. Three feedlines 2 LMR-400 and 1 RG-213, control cables for antenna switching, the antenna rotor cables, lots of spare wires, and a shielded CAT-5 cable for the camera all travel through that conduit.
Mast
The mast is constructed from two pieces of tubing. The outside tubing is 15 feet long and 316 stainless steel. Next a ten foot long 1/4" wall tube that just fits inside with minimal clearance, made from 1018 carbon steel. This second tube is placed on the bottom 2/3 of the mast where it would likely need more strength. The two tubes were welded together at the bottom and plug welded at 7ft from the bottom. A large self-aligning thrust bearing was installed on top of the tower, and some plastic pipe fabricated to keep the rain off the thrust bearing. The mast itself weighs 70 lbs and with the antennas, coax, and other stuff, it all adds up close to xxxx lbs.
About 50% of the mast weight sits on a Yaesu G-1000SDX rotor. And the thrust bearing on the top of the tower carries the rest.
