Thanks very much for the note, Kevin. I haven't noticed my unit's being susceptible to RF (using 1500W output to various antennas). APC claims the output is a sine wave, but I don't have a scope, so
I remember being one of many "controlling" guy ropes attached to a hot air balloon that was used to raise the heavy top section of guyed AB-105 tower with a large monobander and prop pitch already mo
Om my US Tower, I use a 90 degree PVC sweep in the top stand-off, held in place with 10 or 20 mil thick pipe wrapping tape. I tape the cables to the standoff arm before they enter the sweep. Jim N7US

Yesterday, I went to Cable X-Perts in Glenview, IL to pick up two cable assemblies of their version of LMR-400UF with PL-259s attached to use between my remote coax switch and yagis. The connectors w
I bought my climbing belt with butt strap 30+ years ago. It was the best I could find at the time. Now there are federal safety standards, and the body harnesses have not just two D rings on the wais
Roger, Be VERY careful lifting a crank-up tower with a fork lift. It's easy to bend the cross bracing to the point of damaging it or at least making the tower bind when raised and lowered. A tow truc
I know this sounds very crude, but I've spliced Flexweave by tying it with a square knot, even without trying to clean it. I've checked the DC continuity of several of the knots, and it tested fine.
It's fun to dream. Just to be a realist, I can't imagine how much it would cost to refurbish and then maintain the tower if it is usable or how much it would cost to remove it if it isn't. Jim N7US -
I used 3/4" model 377A Z-Rung assemblies from ICE http://www.iceradioproducts.com/ . They are two-part aluminum blocks that fit snug around a tower cross bracing, not a leg, (I have a US Tower HDX-58
We have an Invisible Fence, which is a system sold and installed by franchisees. Before we bought it I had a clause inserted into the contract that the dealer would be responsible for resolving any R
My US Tower HDX-589MDPL, which is motorized with the remote control option, recently took a very large, direct lightning hit. The antennas on it at the time were (and still are) a Diamond 2M/450 vert
Jerry, My questions really were about repairing the tower, but I welcome any suggestions on improving the grounding. The winch was connected to a dedicated 120VAC circuit with a GFI outlet at the bas
I am actually doing the due diligence on repair estimates that I would do if I were paying for it myself and have told the insurance adjustors that. I don't want to be foolish and shoot myself in the
The remote control kit includes a switch box for inside the house. You can raise or lower the tower from inside or outside. To use the "local" control at the tower, you have to switch the inside box
I ordered several (17 or so) Cadweld One Shots mail order, and the igniting power got mixed during shipping with the other powder, and I couldn't get them to fire with the spark. I ended up using Cad
Though my tower has remote control (or did until my lightning strike), I would only lower it from inside, and I did that when I knew no cables could get caught in the tower. It's especially prudent t

I have steps from W9IIX too, and they replaced homebrew ones. I didn't find pictures on the W9IIX web site but they are listed on his order form. I took a picture of one of mine for VE7RF and can for
