The 40M add-on kit works great. I used one on two A-4S antennas I owned for 14 years. The 10, 15 and 20M performance was unaffected. All 4 bands played very well. I have since given these antennas to
I also used the large heat-shrink with the built-in glue and replaced the entire old heat-shrink. Bill, N3RR http://www.mscomputer.com additional 5 percent off
Denis, You have something else wrong. SWR on all 4 bands meets or exceeds the published charts. I've used two of these over 14 years. You should check everything out again. Bill, N3RR http://www.msco

Per the PolyPhaser book, tying these together is useless from a lightning point of view. Bill, N3RR can an 2 all http://www.mscomputer.com additional 5 percent off
Tony, Here's my advise for you. Note, worth reading for others too: Bill, N3RR Ok so far. closer and Yes, and consider this: Where ever you have such a situation (coax switch, or common node point wh
David, You should use solid wire or flat copper strap. You should use as large a ground wire as you can afford! Size 00 wire is fine, of course, if you have the Cadweld molds for it. The spec is in t
Don, In answer to your question, you need to construct a ground-grid around the house, as explained and depicted in the PolyPhaser book. My ground grid encompasses only one side of the house, since m
Rudy, Look at my website and see what I use. It's a Joslyn system and protects the whole house. Works FB! Many overvoltage conditions occur here and the Joslyn device takes out all of the spikes. Pro
I tie-off the coax to the arms and create a drip-loop at each one. This is how I strain-relief each leg of the coax. Bill, N3RR http://www.mscomputer.com additional 5 percent off
Jeff, No, that will not "do". You need to follow proper grounding procedures. Ground rods need to be spaced every "2n" apart, where n=the length of the ground rod in feet. The grid should be n distan
I've never tinned a PL-259 and never heard of anyone else do it, except what's been posted today. I use silver Teflon PL-259 connectors and a Weller D550 soldering gun and strip the RG-213 properly.
Troy, Take a look at the station design outline and the detailed discussion on my website. While I designed a contest station, the process is the same for any application. You will learn a bunch from
Jan, I replaced the cables on my HG-52SS after 12 years - long before the rusty spot became a problem, though there was rust. I did it myself and one other guy at the bottom of the tower who fished t
I must strongly disagree. By disconnecting cables inside your shack in lieu of (instead of) any lightning protection, you are leaving your house open to a fire started by the arc-over from lightning
Joe, Per the PolyPhaser book: "Lightning Protection and Grounding Solutions for Communication Sites", by Ken R. Rand, Published by PolyPhaser, First Edition, Copyright 2000, page 30, the strap may be
