Can this mod be done to a 40-2CD? 73, Dick WC1M _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://
Here's the tool you're looking for: www.towerjack.com. On where to tie off at the top, good question. Unless you put a clamp on the mast, as you suggest, you can't clip the fall arrest lanyard above
Hi. I'm considering buying a used Cal-Av 2D-40 2-element 40m beam and would like to hear some opinions on performance and installation. I'd like to hear from any owners/users on how the 2D-40 compare
Impressive. Must've used a crane and bucket to attach the boom sections between towers. Don't know when he did this, but it would be tough to find that many AB-577s at any kind of reasonable price th

I second Steve's motion: I use two of his tool bags, one on each hip. Also use the large and small canvas buckets from Champion for hauling tools and equipment up the tower. Sometimes I clip the smal
A timely subject for me, what with Spring just beginning here in the Northeast. I agree that the cables coming from the tower should be grounded to the bulkhead panel. I have a related question about
Steve, TowerTalk has been an invaluable resource for me, from installing my first tower 10 years ago, a rotating tubular crankup, to my latest tower, a guyed 110' Rohn 55 thing of beauty with a 3-sta
Hi, While we're on the subject of rotors, I'm evaluating options here. Right now, I'm using a Tailtwister to turn a Cushcraft 40-2CD (about 6 sq ft windload, 24' turning radius, 44 lbs, K-factor = 1,
Thanks for the excellent replies to my previous request for rotor suggestions. I'm zeroing in on the M2 OR2800PX, and would like some opinions on that rotor. The plan would be to use it with a Green

The MA-550 cannot be guyed and there's no kit for it. Guy wires would exert substantial downward force on the tower, and all of this force would be borne solely by the wire rope cables that raise and
Hmm. Well, I stand corrected. I have a manual for the Wilson ST-77B, which I believe was the predecessor of the US Tower MA-770, which is the model I have (MA-770MDP with MARB base, to be exact.) The
Aha! That's the tower I was thinking of. Thanks for the post. 73, Dick WC1M _______________________________________________ _______________________________________________ TowerTalk mailing list Towe
Hi all, I've trammed antennas 7 times over the past 18 months: a 40-2CD up and down (the latter just today), plus three 4-el SteppIRs up and one down and back up again. I'm still not satisfied with t
Thanks, Steve. Good stuff. I'm going to try the tiller method. I think that'll be a much better way to keep the boom from rotating, and it'll also keep the boom perpendicular to the tram line. So far
Difficult when the antenna has no center element. It's a 2-el. 73, Dick WC1M _______________________________________________ _______________________________________________ TowerTalk mailing list Tow
For 10 years I thought I could protect my station from anything but a superstrike, but that was before I put up a 110' tower, and before the summer thunderstorms around here became more violent (Clim
How do you get double nuts on a bolt that has no nuts to begin with? The bolts screw into threads in the rotor casing. There's no way to double nut them. 73, Dick WC1M _______________________________
Sounds like a good argument for a second thrust bearing to keep the mast straight. By coincidence, I just installed a 2-el Cal AV 40 (a rare beast) and an M2 OR2800PX. I bought and installed the wire
