I believe there was an article in QST some 30 or so years ago about problems in using link coupling. My dim reccolection is that , when several turns are used in the link, the inductance of the link
Hi Neal: I think you have 2 primary problems. 1. You can not fully lower the twisted top section into the rest of the tower or it will jam. 2. Unless you are very lucky the twisted top section will c
I totally agree with you Alan. Lowering a crank up under windy conditions is dangerous. If the tower does not have power pull down the sections can stick when the lowering force is greater than the w
h Hi Ron: I have owned a UST TX472 without power winch for 12 years or so. I have been able to replace rotators, cables, pulleys, and bearings by myself using a 2 section ladder against the side of t
You have it right. The weight of the tower section causes it to come down when you crank it down. However, if the wind is blowing hard, the weight may not overcome the sliding friction and you might
A friend of mine, K5EE, now SK, modified a prop pitch motor to screw these things in. FWIW. 73, Dan, N5AR Thought I mentioned this,.. maybe I didn't. I'm on the verge of exhaustion and not thinking r
I have replaced the cables and removed the cable pulleys, replacing the bearings in them on my UST TX472 as described below. I did it by myself and it was not a particularly difficult job. I have als
The recent tirade about the price of gas needs a few facts, and some opinions, injected by someone who has been associated with the oil industry during a career in their research laboratories. 1. Oil
I have received 3 very positive off line comments on my posting from Craig K1QX, Mike W4EF, and Ink N4OO. None negative. Would welcome any other comments off line pro or con. 73, Dan, N5AR __________
I recently put together a set of facts re the oil situation in response to a naive post on the subject. I just realized the original post was on AMPS and I sent my response to TOWERTALK. That started
My water comes from a deep drilled well. The sprinkler system is supplied through a black plastic tubing about an inch in diameter tapped into the well casing at about 3 feet depth. Recently a large
I have noticed recently that a number of hams seem to have a fear of dealing with crank up towers. I have used a TX472 for more than 10 years located first near Dallas and now near Spokane. It is not
Hi Jim. Tilting the tower over with the antenna on it does not give you access to all parts of the antenna. I have seen guys use a step ladder to work on the tilted antenna and I think that is danger
Interesting idea Jim. Come to think of it, I have tilt heads on all of my yagis so could tilt the Yagi over, tie it in that position, then tilt the tower over if desired. I still think it is simpler
I built them using 2 aluminum plates about 12-14 inches square. Rather than using muffler clamps and their U bolts for boom and mast attachment I used 2 muffler clamp saddles opposite each other at e
I saw a similar antenna on a underground building near Denton Tx. The ant was mounted on a telescoping steel pole extending out of the building. The area around the building had heavy fencing and app
One of the few things a ham can clone easily is an antenna. Most of us have a pile of aluminum tubing and could easily build a copy of a $2000 antenna design. There is a great deal of engineering exp
Chuck, there are quite a few types of coil clips. Some to contact flat coil conductor and some to contact round wire conductor. I don't know of any that are made of copper. The ones I am familiar wit
Of course, everything Steve says about the comparison is true. However nothing has been said about installing antennas on the tower. The self supporting tower allows yagis to be raised vertically wit
Art, 2-5 years is a long time. You are an accomplished and enthusiastic ham. You need a tower and a yagi. I hope you have no problem with covenants or local restrictions. If I were you, I would put u
