I cut a piece of 5/8- inch plastic tubing to a length of 5 inches and cut the 1/2-inch aluminum rod (tubing will work) to 24 inches. Say no to HOA Antenna restrictions! In this case, the driven element is one piece, and everything is shorted to the boom, to the mast and to ground. The gamma match is held on by an insulated strap at the end closer to the center of the driven element and by a conductive aluminum strap at the other end. So I make do with a long, thin random wire that works nicely as long as the New England wind, snow and ice dont conspire to give my hamming a holiday (which happens more often than Id like).

Other pertinate information and articles from using diodes and resistors to control current, and useable information about antennas are listed there. , Using the very unscientific method of comparing S-meter readings, the beam showed very good side rejection and a respectable front-to-back ratio. So far so good. I used flat plastic stock and flat aluminum stock (1 inch by 1/16 inch cut to 3 inches worked fine) held in place by copper clamps (designed to hold copper pipes to a wall). WebBuild a Portable 10 Meter Yagi Antenna Dave Tadlock 26.9K subscribers Subscribe 34K views 8 years ago A simple 2 element 10 meter yagi antenna ready in time for Field Day Materials: Except the aluminum tubes and rod, you need three aluminum plates 15X15cm to support the elements up on the boom and one more plate 20X20 to support the boom to mast. This is fine for permanent installations, but not something to he bothered with while operating portable. Webohms coaxial cable with antenna's low impedance. This will also have an effect. Right in the middle, cut one of the two wires and cut back about 2cm from each strand. , 3.

The TV mast (with the crimped end lopped off) fits in my trunk and allows two elements to be mounted 4 feet apart and fed with RG58 coax. 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. I was overjoyed. % of people told us that this article helped them. In this project author explains how to

I needed 35 feet of tubing (plus some to fit inside each telescoping joint for support). The inner conductor, carrying the RF current, is tapped out on the element matching point. If you cant achieve a match, slide the entire matching section toward or away from the center of the driven element. (function() { Solder the connector to the cable instead of crimping it. As you may have noticed, this antenna uses plumbers delight construction. Slip on a corner clamp and then a 2 We use cookies to make wikiHow great.

Approximate Resonant Feedpoint Impedance = 135.777 Ohms before added matching section. Right in the middle, cut one of the two wires and cut back about 2cm from each strand. I cut a piece of 5/8- inch plastic tubing to a length of 5 inches and cut the 1/2-inch aluminum rod (tubing will work) to 24 inches. Say no to HOA Antenna restrictions! In this case, the driven element is one piece, and everything is shorted to the boom, to the mast and to ground. The gamma match is held on by an insulated strap at the end closer to the center of the driven element and by a conductive aluminum strap at the other end. So I make do with a long, thin random wire that works nicely as long as the New England wind, snow and ice dont conspire to give my hamming a holiday (which happens more often than Id like).
