TT: This isn't as far-fetched as it might sound. Ignoring the reporter's layman description of the physics involved (power dropping off the line), there are practical applications for such capacitive
Doc et al: Yes, grounding/earthing of the barbed wire at regular intervals would then be required to make the installation safe to humans and livestock, although at every fence post is overkill. I've
TT: When I look at the photo, I see the installer atop the second INSTALLED section, fixing the pulley to the top of the INSTALLED section, with the third yet-to-be-installed section sitting on the g
Jim: As you can see from the patent app, it's been over twenty years since I worked on this system. My memory is ...., uh.... hmmm.... what was I saying? I'm afraid I can't give you quantitative answ
TT: BOTTOM LINE: On a tower, as in driving a car, there are no such things as an accidents. Let's be careful out there! 73 de Gene Smar AD3F _______________________________________________ See: http:
Andy: If you can arrange it mechanically, paralleling two or more wires for your gamma wire will give you a bit more bandwidth. I used two #14 stranded wires, supported by several PVC T-shaped arms,
Jim: My suggestions embedded below. 73 de Gene Smar AD3F Instead of tying the copper flattop portion directly to the tower and risking fatiguing the wire by strong winds, you should consider terminat
TT: At the age of 13, too, I used the same 2x4 mast, set in about a half-cuft of concrete (I said I was 13!)and guyed to the back yard fence. A half-inch carriage bolt served as a pivot for lowering
Doug: I'd suggest you paint the inside and outside of the concrete-encased portion of the aluminum pole with Bitumastic or similar bituminous coating. I can't recall the chemistry, but when we EE's d

Troy: At the top of my tower's mast, at 80 feet, I have a Comet GP-15. It is a small stick, about 7 feet tall, that covers 6/2/440. To connect to it you'd need a triplexer, but Comet make them, too.
Bill: In addition to Red's and Phil's advice, ensure that your ground wire connection to the tower leg does not form a right-angle at the base of the tower. That is, make the connection high enough u

Bill: I have a 64-foot Trylon in my suburban backyard. I, too, had considered painting same after I installed it in 2001. After reading the advice of folks here on TT and thinking about it, I decided
TT: I make/made my staples out of wire shirt hangers. Cut a piece about 8 inches long, bend it in half - vi-oh-la - staple! Some of mine have been in the ground since 1998, and I have buried about a
TT: As I've written on TT before: The difference between theory and practice in theory is less than the difference between theory and practice in practice. Put up a wire and get on the bands. 73 de G
Rich: If the choice is between 3 and 4 inch conduit, go with the 4 inch. Also, as others here have said, use sweeps not elbows for your angle turns. The sweeps are large radius curves that don't forc
TT: I had the same problem hauling my Skyhawk up the side of my Trylon. I had to haul the antenna up to the mast nose forward, that is, with the directors pointing up, so it could clear the trees in
