Bob, Hire a tree climber to remove and re-install, using a rope with lower breaking strength than the wire. Then if it gets snagged again the rope should break not the wire if you pull on it. Also co
I'm trying to replace the worn sheave on the top pulley assemblies of two Rohn EF-2545 gin poles. This appears to be cast aluminum with a 5/16" bolt going through the center hole. The sheaves measure
Herb, Sounds like you are looking for some "bent pin shackles" such as those sold by DX Engineering: https://www.dxengineering.com/parts/dxe-bps-j732 A friend gave me a bunch of these years ago and I
There's been much discussion of these on Tower Talk over the years; try an archive search. I've used elevated guy posts at three QTH's in Delaware since the early 1980s. Some have been I beams and ot

Richard, I agree it's good to put the relays at the base of the tower for easy access. I first learned about using different length feedlines in stacks from Dallas Carter, W3PP (SK). He wrote an arti
Tonno, I have numerous phased Beverages on 160 meters. 120m spacing is ideal for broadside pairs on 160. I have a pair toward Europe with each wire 163 meters long, and this is generally equal to a s
Ed, I first learned of this tragedy from a friend this morning, and have been catching up on the news reports. This report indicates there was a shackle failure: http://wirelessestimator.com/articles
I have used various shunt-fed and series-fed towers on 160 meters that had a variety of antennas, from UHF to HF, and rotors, and never had any issues with RF from 160 causing damage to things at the
I have used a similar pole with No. 18 enameled wire as a 160-meter inverted L. That is fairly light wire yet strong enough to endure for long periods. 73/Jon Jon P. Zaimes, AA1K Tower climber for hi
All of my Tailtwister (T2X) rotors (I have seven on seven towers, plus a couple of spares) use a larger size mounting bolt than the Ham series. T2X has six 5/16" - 18 bolts, 1 5/8" long (as confirmed

Hi Eric, Have you replaced the starting capacitor in the control box (if it is still located there)? Common cause of intermittent operation and a cheap part. If you haven't already, look at the tower
Maurice, K3EJJ, has been machining various bushings to use instead of the typical TB3 or TB300 thrust bearing. A number of these are in use in the Baltimore area, where I encountered one for the firs
Ron, Found this on US Tower website. I think it has the specs you want: http://www.ustower.com/wp-content/uploads/2017/01/MA40.pdf I installed a new MA40 a year or so ago (for a client) on an older M
