Newington, CT, 06111-1400 USA She could see that I was clear of the antenna before keying the transmitter. Required fields are marked *. If you are suggesting using a metal structure as the radials (aka the ground plane), then give it a try. , [ : (, )] A bumper-mounted vertical is fine for casual operation, but it leaves a lot to be desired when mountain-topping for rare DX. Wireless is what they called it back then, and still to this day, wire antennas are sending signals out on the airways. Tuning caps are as scarce as hens teeth nowadays, so I decided to try a technique Id come across in the 1974 ARRL Antenna Book** incorporating the capacitor into the structure of the gamma match. High voltage coils were used for their power, and it systematically sent out the familiar "dits" and "dahs" of Morse Code, and the party or parties, at the other end who could read Morse Code wrote the symbols down, and they made words. Normally the capacitor should be tuned first, but as you will find if you construct the antenna, the fit of the the inner rod, the plastic tubing (the capacitors dielectric) and the outer tube is quite tight. All practical antennas have some directivity -- putting out more power in some directions than others. Ideally, you would like to put power out (and receive from) only in the direction toward the station you're talking to. A "beam" antenna, designed for directivity, can increase your signal by 1 S-unit (6 dB) or more, receiving and transmitting. In this case, the driven element is one piece, and everything is shorted to the boom, to the mast and to ground. The driven element isnt split into two legs like a conventional dipole. wave dipole is zero, the outer conductor of the coax is connected to the element at this point. One 1-inch tube was cut in half, yielding two four-foot lengths. Tel: 1-860-594-0200 | Fax: 1-860-594-0259 There was nothing left to do but try it out on Beseck Mountain. M Logitech Co., Ltd.
