Don Sounds like your on the right track with the trapped dipole. Another choice might be to use a random length wire and good ground with any of the many automatic ant. tuners designed to end feed long wires. Used one in a mobile installation with a 17 ft whip with reasonable success.

The antenna inventory at ARS N3RHT: Radio works 80M Windom, one end in the attic and the other end in a tree at the far corner of the property, with ends drooped down to fit the space, fed with coax Homebrew vertical dipole, about 40 feet total length, stuck upright in a big ole pine tree and held lovingly in place by the tree's branches, fed with 450 ohm ladder line to a Heathkit B-1 balun and then coax into the shack. Butternut HF-6V with the 160 meter option, on top of a 30 foot pole with a home-made counterpoise following plans published in CQ. Some of the counterpoise wires have broken. Fed with coax. Homebrew from one of the W6SAI books 10-15-20 multi-band meter dipole in the attic, center is Van Gordon 1:1 balun, tuned to resonance using MFJ 259, and fed with coax The other stuff is VHF or too junky to be worth mentioning. In a few weeks, I will put up that 1977 NOS trap dipole that I mentioned. My house is on a small, suburban lot, but that lot sits on the highest point for 20 miles in all directions. Anyway....that's what I'm working with here. All ideas appreciated. 73, Don Merz, N3RHT -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, December 13, 2004 5:59 PM To: Merz Donald S; [EMAIL PROTECTED]; [email protected] Subject: Re: [AMRadio] Antenna Tuner Wonderings Don, What kind of "crappy" antennas are you using, i.e., doublets fed with coax, open wire lines, etc., or end-fed wires? Or, some combination of types maybe? Rather that building up a bunch of tuners you might consider putting your efforts into erecting a set of antennas that all worked directly off a 50 or 75 ohm coax feedlines. Half-wave dipoles, one for each band, for example, or one or more of the multi-band arrangements (G5RV, fan and trap dipole, etc.). Dennis D.
