Looks like I'll probably wind up roof-mounting a vertical antenna to get my station back on the air. Because the chimney is too close to the ac power and drops, the best alternative is a tripod or qu
But it does this bridging in 150-ft increments. BTW, only a real mayonnaise jar will work, the jar containg "fake" mayonnaise won't work. Leaving the mayonnaise IN the jar makes the performance even
No, Barry, you need two D cells, four if you live in the southeastern US 73, Bob AA0CY There have been some interesting theories proposed lately, such as leaving your tower and antennas ungrounded so
There is a "typical" commercial site grounding check list in Appendix B (I think, don't have the book in front of me) of the PolyPhaser "Grounds" tutorial. I have decided not to reply to the various
EIA/TIA 222 F requires that all guy anchors and ground rods etc be galvanized to prevent copper-galvanized corrosion problems which allegedly led to tower failures. There is disagreement on how far a
PolyPhaser is not the only game in town, true. BUT, they are the BEST. (Tests performed by qualified and disinterested 3d party laboratory.) 73, Bob AA0CY We keep talking about Polyphaser like they a

<sni>-- Eric, my tower is, for a number of reasons, adjacent to my shack, and my service entrance is at the diagonally opposite corner of my house. A 90-100 foot run around the periphery of the house
All the discussions about where lightning will strike remind me of the tornado warnings and watches I listened to while living in Denver (which, for those who don't know, is the western terminus for
Through most of the postings on this subject runs the common thread of direct strikes. In actuality, it is the indirect (or nearby) strike which causes most of the problems. A strike can occur quite
Several college engineering students in Florida were hanging around the dormitory during a thunderstorm. One posed the question of whether lightning could strike twice in the same location. Opinions
GAP Titan gets my vote (I have one). Been using GAPs since 1990 and satisfied. Actually a conventional 1/4-wave trapped vertical such as the 14AVQ with an eight foot ground rod works very well. Back
The Titan does NOT require guying. Mine survived several years of Nevada breezes (80 MPH gusts) unguyed with no problems. It is triple-walled at the mounting area and double walled the next eight fee
I also think the Butternuts are great antennas but I have heard they require guying or they're history. Comment, Lee? 73, Bob AA0CY I like the Butternut verticles. yes, they work better with a ground
However, the Hustler doesn't use a SO239 connector, but pigtails off of the coax. Weatherproof it or else (especially in sunny Seattle) :) 73, Bob AA0CY/7 Kent, Wash. (about 20 miles SE of Seattle) S
I don't. 73, Bob AA0CY To: <towertalk@contesting.com> Having had all major types, I agree with Lee.... All no-radial verticals suffer greatly when mounted near earth. If I was in that fix I'd just bu
Frozen ground won't absorb surge energy. 73, Bob AA0CY PS What is a french drain? More to the point, what does the frost line have to do with buried wire, anyway? If you don't bury radials that deep,
For my purposes, the GAP did a good job. I'm not saying it's the best around, however. I didn't care for its performance on 80 either, but it wasn't a band I spent much time on anyway so I didn't pus
<snip> (snip) I asked Roger Cox of Hygain whether putting radials under a DX-77 vertical (also a vertical dipole) would be of any benefit. He said NO. 73 Barry -- Barry Kutner, W2UP Internet: w2up@it
I had a Challenger in Colorado. The counterpoise (used to increase bandwidth on 40 metres) ius supposed to be about 57 feet in length. This antenna worked very well for me on the bands it wasn't supp
