As other have said, box ratchets are very handy, but there are limitations. My first set of these was the Craftsman model with fixed-direction ratchets. You have to flip the wrench over to reverse di
I agree -- PB-Blaster is much better than WD-40. But use it in a well-ventilated area. It's very noxious. 73, Dick WC1M _______________________________________________ _______________________________
Shameful. No more comment needed on that rudeness. I must have missed the original question, but the question is not totally out of line. If the antenna wind area is small, and the amount of mast sti
I have a full set of suppressors at the tower and shack ends. I think this is important for protecting long cable runs between the tower and shack. In my case, it's 225 feet for one tower and 265 fee
No, I don't see any reason why you shouldn't use 24VAC relays, provided the relay contacts are rated for 110VAC and the current drawn by the motor (I don't recall offhand how much current is drawn.)
True, but you have to prep the sections yourself, which takes a bit of time. Might be worth $50 to have someone else do that. First, you have to cut slits in one end of each piece of tubing. Then you
I have a single 8-wire cable run of about 350 feet, and I've not have any false/missing pulse problems with an M2 OR2800PX turning a 16 sq ft antenna. But read on. After deciding that the M2 OR2800PX
Thanks for providing the web space, Scott. My father in-law and I were at Bill's in August of '03 when the big crane lifted the top half of Bertha onto the bottom half and K7PN welded the halves toge

Per my previous post, also looking for good scans of the manuals for the Cushcraft 15-4CD and 10-4CD. The resolution of the PDFs on Cushcraft's site is too low to read the dimensions and spacing of t

Looking for a design or commercial version of a 15/10 duo-band yagi, preferrably at least 4 elements each band. Does anyone have a design or know of a commercial offering (past or present)? 73, Dick
Steve is right: AB-577 guys are 1/8" galvanized or stainless steel. That's below spec for Rohn 25. Further, the AB-577 guys are tensioned with "snubbers" which clamp the guy wire. Not at all clear th
Rohn 55 is a little different in several respects. First, at 100 lbs per section, it's a lot harder for two people to lift two or three sections onto a pier pin. Second, after the first set of perman
I wouldn't add extra guy sets to the stock AB-577 with the 75' extension kit (follow the 'LXC Directive!) When properly anchored and tensioned, the guys that come with the mast will make it quite sti
I'll second Bob's comment about the bubble level. It's useless. The rest of his comments are spot-on in my experience. I didn't mention earlier that I have three AB-577s, one with the extension kit,
