I was fortunate in that I didnt have to mess with the capacitor. 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. I now had a capacitor! I did the same at one end of each 7/8-inch tube. 3PL . I would make the adjustments while Donna, visible through the shack window, keyed the transmitter and recorded the SWR readings. . A bumper-mounted vertical is fine for casual operation, but it leaves a lot to be desired when mountain-topping for rare DX. If you cant achieve a match, slide the entire matching section toward or away from the center of the driven element. These clamps are shaped like a letter C, come in all sizes, already have holes in them for attaching to the straps, are easily bent to fit around the 1 inch element, and are inexpensive. , [ : (, )] The inner conductor, carrying the RF current, is tapped out on the element matching point. WebHow to Build a 10 and 11 meter 1/4 wave Ground plane that almost no one can see. Leaving the hose clamps over the element slots loose, I adjusted the driven element length to about 17 feet and the reflector to about 18 feet 1/2 inch. Solder the connector to the cable instead of crimping it. As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). It was well worth the effort.

I then cut a small piece off the un-swaged end of the second five-foot TV mast (so it would fit in the trunk) and installed it into the tripod. More Ham Radio Links. In the past I had used a U-bolt and clamp arrangement, but this technique requires care in keeping the elements parallel to each other and to the ground. I havent experimented with the reflector length yet to see the effect on the gain and the front-to-back ratio. Continue measuring to 7 ft-105/ 16 inches (Figure 9, dimension W1A) and mark the wire, recheck the measurement and cut.
