Are you suggesting a T, with the crossbar being 1/2 wave in length and connected to the device at the center and formed by wires? How close to 1/2 wave is close enough? > Placing the unit a little less than a 1/4 wave in front of a reflecting unit > (file cabinet?) may exhibit some gain as well. This I do understand, but it's unfortunately quite impractical. I'd really just be happy with something I could hide somewhere in my car that would make the transmission to the antenna in the rear window a bit better.
