OK, that brings up something about which I've been curious: exactly how do you jack up the mast? Someday I'll have to do that to get my Orion rotor out for service, and I can't quite picture the proc
I thought about dropping the rotor plate. But I worry about matching the exact height and level it had previously, possibly causing alignment problems. _______________________________________________
Thank goodness it wasn't more serious. Hope he gets well soon. W2GD is one of the best contesters around. Hope we get some details on what happened. I can only think the temporary guys weren't tight
Ron, You're asking the right questions. I have a U.S. Tower MA-770MDP with the MARB-770 base. In the 11 years I've owned the tower, I've had three different antennas on it: a Hy-Gain TH-7 tribander a
I use a ladder with my MA-770. Instead of leaning the ladder up against the tower, I extend it to 20 feet and strap it to the tower with heavy duty cargo straps every 4-5 feet. Then I can climb the l
Scott, In the stock version of the RMC-1000, the control box has to be connected in order for the "local" switch on the RMC-1000 to work. The control box POWER switch must be flipped on, which energi
Hi Bud, Sounds very similar to my setup. The main difference is I'm using three 4-el SteppIRs instead of three KT36XAs. I originally had a 40-2CD at 110' being turned by a T2X, but replaced it with a
Frank, I had a nearby strike last year that fatally damaged the driver and CAT boards in all three of my SteppIR controllers (I have a 2-stack of 4-el SteppIRs.) The surge propagated through the Step
The best way to grab a cable without damaging it is to use a Klein grip. You can see one at this link: http://www.championradio.com/rigging.html Scroll down the page a bit and you'll see it. If you w
I'd like to hear from anyone who has successfully used crimp connectors on Davis Bury-Flex coax cable. I need to know the part number of the connectors and the technique used. I recently bought an RF
Thanls for the response, Steve. I'm certainly leaning towards soldering. The .128" cavity crimps the center pin on Belden 9913 cable. (In italics) This is the only die set with a .128" cavity for 991
I installed an M2 2800 recently. I used the centering piece, but I also used the stock mast clamps. I like the idea of the centering piece because it makes it easier to center the mast over the rotor
Excellent question. I wondered about that myself when I installed my Phillystran guys. Seems to me if the cable is properly tensioned, there won't be a lot of flexing at the end of the grips, so ther
I've never been impressed with the jacket material used in LMR-400UF. Seems way too soft, amd I think it either softens or gets brittle over time. Or both. If the cable flexes at all, it's easy for t
Lots of questions. Here's what I did on my 110' Rohn 55G tower: 1. I fully tightened each guy set immediately after installing the guys, so that the tower was plumb and properly tensioned at each lev
You're lucky, Pete. About 12 years ago I dug up a rod that had been in the ground only 3 years. The clamp had completely disintegrated and the wire was no longer connected to the rod. Must be a lot m
Well, this must be one of those YMMV situations. All I can say is that on EHS near the 10% target tension, my Loos reads about 30% high compared with a Dillon dynamometer. At the low end of the scale
W8JI compared the readings with EHS and fiberglass guy material in series and found a large discrepancy. As far as I know, he didn't compare EHS and Phillystran. My experiment compared the readings o
If you use EHS or wire rope for tramming, you should use a pulley or trolley with steel sheaves. Plastic sheaves can be cut in half by a steel cable. Aluminum sheaves are too soft and can be grooved
