Hello All,
Please reply to me directly if you would please. We have far too many OT threads that take on a life of their own. I own a KX2, KX3, PX3, KXPA100, and K2. I love my Elecraft rigs. I have learned much from this list so thought I would ask a question. Background: I took down my 50 ft. Rohn 25G tower and Cushcraft ATB-34 beam (old) when I sold my house. I am building a new home and I am considering two setups for my tower. I don't want to climb a tower anymore and I am trying to keep my XYL happy by not putting up so tall a tower. I know it won't perform as well as before. Four horizontal ft. of my roof will be 23 ft. above the ground. The peak to the east is about 12 ft. from the tower. The rest of the roof is 20 ft. from the ground. The yard slopes downward to the east. The house is high on a hill looking east. To the west the ground is gently sloping up. I know my proposed free height (8-11 ft.) above the roof isn't ideal. Since I already have 5 sections of tower, I want to try to use them. Here are my two ideas. 1. Putting up two 10 ft. sections and a top 9 ft. section of Rohn 25G. I will mount a new Mosley TA 33-JR. on it with a mast putting the beam 2 ft. above the top section. This would put the beam about 31 ft. above the ground. My rotator is my reconditioned Alliance HD-73. I estimate the total weight of tower and beam at just under 200 lbs. I would like to put it on a tilt over base, either custom built or the Rohn if it can take the load. The tower would be attached to the house at the 13 ft. level, leaving 16 ft. unguyed. I would have a pulley system at the 12 ft level of the house to lower the tower. Is this setup something that will work? I am concerned about the load on the hinge on the base as the tower tilts over. 2. Put up one section of 10 ft. tower and a top section. Put an aluminum mast in place that sticks up 12 ft. above the top section. Everything else is the same. This reduces the weight a bit and has only 6 ft of unguyed tower. I just don't know how well 12 ft of mast above the top section will work. I would appreciate any advice anyone could give me. Thanks!
