Congratulations on moving back to 7 land Bob. Although I have a 5 call from many years of residence in Texas and Oklahoma I live near Spokane. It sounds like you have a great place there and will hav
An additional problem with your proposal, Bob, which I neglected to mention is that when raising or lowering your tower the guys are slacked off and provide no side support at all. The tower would ha
Terry, I am using a 2800 with over 300 ft of conductor. The pulses feed thru 150 ft of rotor conductor cable into 2 conductors of Romex type buried cable with no problems. I suspect your problem migh
Try www.cebik.com There is quite a bit of information there on top hat loading. 73, Dan, N5AR As a visitor to Towertalk from the UK I'm trying to find some information on alternatives to umbrella top
Tony: I have a TX472 with the TRX80HD fixture. I replaced the ball bearings in the tower and the fixture a couple of years ago. The pulley in the fixture is the same one used in the tower. It uses a
My friend K5EE (now SK) adapted a prop pitch motor to do the job. I don't remember much about it but it had handles on it. I think a PP motor would be a good start for building a screw in tool. 73, D
We frequently complain about service from the companies we deal with. Here is a true account of a couple of good experiences I had recently. I own one of several 131 ft motor driven towers built by U

Gary: For splicing across a suspect joint in a yagi element I would take up some scotch brite pads for cleaning the surface, 2 hose clamps, some Alox and a piece of soft aluminum strap. I think you c
My TX472 does not have power pull down so I slip a piece of pipe inside the tower at the bottom and lower the tower so the top section rests on it. This holds the top section up so the rotator is acc
I believe that it is also important that the pulley have a large enough wheel diameter and the groove have a radius which fits the rope diameter. Otherwise the rope will be flattened as it rolls over
The raising fixture on my TX472 has a 2 to 1 mechanical advantage. The cable end is attached to the top of the fixture, goes thru a pulley attached to the tower, back thru a pulley at the top of the
