Does anyone have a fairly new copy of Steve's Mast Antenna & Rotor Calculator? My 1997 Ver. 1.0 is outputting unreal torque numbers, 7215 ft-lbs (not a typo) for a full size 3L Wilson 40M Yagi. That'
Ten years ago... yep, that's just about the time the a**holes started hitting the scrap bins in the yard outside the warehouse. They especially liked to steal the copper absorbers from old solar-ther
Concrete prices seem to vary all over the place. Out here in the SF Bay area it currently runs $120/yard for the "regular" stuff and $132.50 for six sack - 3/4 (4000-psi) mix. Pumps are typically $10
I'm going to be running some DC powered equipment on my tower. Preamps at least, maybe a downconverter and perhaps a 1.2 GHz brick. I've been planning to run power to the tower and install a DC bus i
Hey Gene, Too bad the hoplophobes are in charge back there in DC, you could put one of those guard shacks out by your garage or tower;-) 73 - JC, K0HPS PS: I'm not thumbing my nose at you; it's as ba
Hi Joe, If you really want to run a mast all the way to the bottom of the tower I'd go find a used thrust bearing (the kind that's designed to support both axial and radial loads) at the junkyard for
Hi Natan, Based on my experience with the OSCAR satellites, I don't think you'll have a problem. I don't notice any signal degradation when the satellites pass overhead such that my tribander gets be
I can't seem to find it in the archives but I know someone recently posted a link to a gin pole designed for the triangular legs of the Trylon and AN-W towers. Would you please post it again? Thanks
I'm reassembling an old Hy-Gain TH3-Mk III that I got from an estate years ago. When I reassembled it back then I used the Butter-its-not product from the Butternut antenna folks, and of course that'
I found some GB OX-GARD in one of my antenna parts boxes. That should work better. I think the Pentrox is more for stainless steel. I like Penetrox and Noalox for this application. Just be sure to cl

I meant to say Permatex, not Pentrox. Absolutely not. Penetrox A has a petroleum base with suspended zinc and it is for aluminum to aluminum connections. John KK9A I found some GB OX-GARD in one of m
Thanks for that suggestion, Jake. I've got the Ox-Gard and the green scrubber pads. I was going to use kerosene but I already have WD40. JC, K0HPS, is looking for a substitute for Butter-its-not: JC:
Thanks, Charlie. I got mine from Ace Hardware. I'm lucky to have a huge Ace just a 5-minute walk from my house. You can get conductive anti-seize grease from Menard's or another big-box store like Ho
I remember when the Garden City towers first went up. It allowed us to get our first TV. K0HPS 1800 Thats going to leave a mark. XX/7 _______________________________________________ _________________
Hi Mike, I did exactly that same thing years ago. Used an auger to dig the base for my MA-550MDP. I also had the motorized raising fixture. Unfortunately, I'm away from home and don't have access to
