Paul: Jerry Sevik, W2FMI (the balun king), in his book, "Building and
Using Baluns and Ununs: Practical Designs For the Experimenter," (CQ
Communications) writes extensively about his experiments with shortened
verticals. In addition to information on baluns and ununs, the book
contains four appendices covering the design of shortened verticals, their
ground systems, and loading coils.
Inasmuch as I, too, live on a 50-foot lot, I am looking to Dr. Sevik for
the design of a 160-meter vertical antenna that will amount to more than a
wire dummy load.
A second really neat antenna design for 160 meters (and above, actually) is
the small transmitting loop described by Ted Hart, W5QJR, in recent ARRL
antenna handbooks (I'm looking on page 5-11 of the 17th edition). These
antennas actually cover a range of frequencies. They are built of 3/4-inch
copper tubing and must be remotely tuned--but they will fit on small lots.
The design that interests me is a loop that covers 160 through 80. It's
30-feet in diameter, but in a vertical plane, is relatively easy to fit on
any lot. Also, Hart gives design data for building antennas with or
without radials.
If the neighbors ask what it is, tell them its a Stargate, and if they
don't stop complaining about it, you'll toss their kids thru and they'll
end up on some desolate planet on the other side of the galaxy. Or better
yet, tell them you'll go there and come back with some "really wierd" new
neighbors.
Good luck, Paul, and 73 (just kidding about the Stargate stuff),
