In Reply to: I don't know who it was that suggested vertical mounting of a dipole. posted by Todd A. on November 23, 2006 at 14:47:27:
I did mention it in one of my posts a month or so ago, but can't take credit for the idea. It's as old as the dipole itself, and well known amongst radio amateurs. It's a great solution to 2 problems. One is the need to turn the horizontally mounted dipole broadside to the transmitter. The other is the high cost of a half-wave end-fed whip, such as offered by Fanfare and Magnum/Dynalab. They can easily be replaced by a home-made twin-lead folded dipole vertically mounted in the attic as high as possible, connected to a 300-75 balun/transformer (about $3.00) to feed the signal to the tuner via double or quad shielded cable (actually, the end-fed whips are pretty much just expensive ways of duplicating the performance of a vertically mounted dipole in a more attractive and space-saving package). If mounted in the attic, the signal gain is considerable vs. mounting in the listening room. An incidental advantage of a vertical is that it is less susceptible to pickup of multipath interference than when mounted horizontally. Sounds like I know a lot about antennas, no? Wrong, I got all this from just looking around the Internet and at the ARRL manuals.
