The crank on my free standing crank-up, tilt over tower failed with the tower up at about 50 feet. The shaft that holds the crank sheared - when I tried to crank the tower down. I raise and lower thi

It has only happened once to me. But I will consider replacing the friction break winch the next time it seems abnormally hard to crank. It appears the failure is associated the plates sticking toget

The crank on my free standing crank-up, tilt over tower failed with the tower up at about 50 feet. The crank on the winch that raises and lowers a Tri-Ex 54 foot tower failed, with the tower raised.

Hi guys. I have appreciated the fun with the name for wench and winch - with winch being the correct term. I have been asked to make a presentation to the local club, and submit the write-up to a clu

Remember to use braided wire for the pigtails. Solid wire is to rigid and has a tendency to fail. Terry - W6LMJ _______________________________________________ _______________________________________

That was my experience with Karl as well, back in 1995 when I received the first building permit issued in Palm Beach County for a tower at hurricane Andrew. I sent him a copy of the engineering that

While away this summer I had a tropical storm pass through my area. It hit the tower, and seems to have caused the rotor to loose its orientation. When I turn the beam counter-clockwise, north lines

Terry, thanks for the response. It appears the same symptoms can be produced by several different problems. I am pulling the tower down today and looking for water in the connector. I don't expect th

Craig, thanks for the feedback. I am planning to do all of that today. I am trying to get all of the tower tended to before the next set of hurricanes hit West Palm Beach. Today is my last chance for

Bill, do you have the raising and tilting fixture? I seem to recall that you use the same pulley in the upper position to raise the tower and the lower position to tilt the tower. First, with the pul

Has something happened to Hy-Gain? I have not been able to reach them by phone or order parts online. I called MFJ, they say Hy-gain is fine, and right next door. I finally asked MFJ to contact Hy-Ga

Last year I replaced the Fulton K1550 winch, after the handle broke off. This year I think I will replace the other winch, this time with a K2550 model and re-cable the tower. What is the best source

Thank you one and all for the comments. I have worked with Karl before. He helped me - 13 years ago - when I got the building permit to put up the tower. He is a great guy to work with. I spoke to hi

Thanks Don. I suspect I will have a similar situation. Now if I could just get Hy-Gain to respond and sell me a few parts for my TH3MK4. Terry - W6LMJ _______________________________________________

I have a Yaesu G-800 rotor and while it turns fine, the rotor control only moves about a quarter of the dial, but the rotor itself appears to be turning nearly four times that amount. Any idea what m

Steve, very interesting. So the rotator is most likely good, and the controller in the shack it most likely bad. I actually have three of these rotators, but the plug at the rotator is different, so

Hy-Gain is busy and has responded. The reason my online order didn't go through is my spam filter trapped it. Not answering the phone appears to be tied to Hy-Gain being undermanned. I sent an e-mail

You use to be able to get these at Radio Shack. Now I understand Lowes, or Home Depot is the place. Has anyone bought one in the last year? Does anyone have a source of push of masts that they would
