I'm considering erecting 50-70 foot tower on the land behind my house. I presently have another located in the only clear spot that conforms to the town's zoning law regarding amateur towers. "The to
will differently actually Bob, you can do it but it isn't straight forward. The late, great Gerry Mathis W3GM used a "falling derrick" method to tilt over 100' of 25G with large arrays attached. I h
Doesn't the feedpoint impedance vary according to the frequency? Paul, N0AH didn't tell us at what frequency he was taking reading. I experienced the same "problem" when erecting a 40 meter home brew
As an example of long term testing. I recently dug (and I mean dug) a 10 meter yagi out from under a deep pile of leaves turned mulch in the corner of my back yard. It had been there since 1986, elem
Ray, if I could offer only one piece of advice on the A3 refurb, that would be to mark the outer traps on the director elements before disassembly. They look the same as the outer traps on the driven
Yes. 3 pair of hands should be more than enough. I've done 30' of 25G with myself and a one other person. You won't need the rope. Tom Hybiske K3GM _______________________________________________ See
My coax entrance panel is now hooked to its own series of ground rods. I want to bond it and all of the Polyphaser arrestors attached to it to the utility ground rod. If the easiest and shortest path
Will the Alfa-SPID rotor fit inside 25G, and can it be done without separating a section? Thanks, Tom Hybiske, K3GM _______________________________________________ ___________________________________
I made staples by hundreds (5000 feet of radials) recently. I purchased a few spools of baling wire from HD, cut 8 inch pieces, and after they were all cut, bent them around pencil one winter evening
It seems like the last thing you'd want to do, doesn't it? But simply put, you want your entire ground circuit to "bounce", or rise as simultaneously as possible during a strike event. The object is
Sorry to hear about the poor results, Jack. You didn't mention what brand or model drill you were renting. For hammering ground rods, I'd recommend something like a Hilti TE-74 or TE-76. Hilti is top
Funny, I just called a tree guy today about clearing some big pines in my woods for a new tower of the same height as yours. I've decided to clear only the immediate tower area, plus "guy lanes" to p
Just getting around to answering this one. When using an actual Nicopress hand swaging tool, once the swage has begun, the jaws will not open until the swage has reached it's specified outer diameter
sri, but I read these in bulk, and this one might be played out I use Coax Seal it on all my connectors, and find it excludes moisture the best. It does so by filling in the threads rather than cover
Reading the Towertalk archives, it became apparent that 3 Chicago grips are favored during the guy tensioning and tower plumbing process. Do I've got 3 Klein 1613-40 grips, and 3 come-alongs. What I
The Lug-All is of those lifetime tools, but it also commands a considerable price. Three of them could well set you back six to eight hundred dollars. The Maasdam is well built and is fine for the we
Hi Joe, I had the exact problem you speak of at a former QTH. I had a hinged base plate and wanted to be able to walk up 40 feet of unloaded tower. The problem was when the hinged base plate was orie
I use a 15' length of 6061 T-6 schedule 80 tubing (heavy wall!) for my mast. There's a 3L SteppIR about 2 feet above the bearing, a 2m K1FO weak signal yagi, and a VHF/UHF vertical on the top. It's b
I used one previously, ground mounted, a couple inches off the soil, and over a very large radial field. The antenna feedpoint impedance is around 50 ohms when mounted only on a pipe. Adding radials
The Hustler BTV series are great antennas. But unfortunately Hustler tunes them according to how a large majority of the amateur population (especially new hams) use them; that is to bang a pipe into
