how to build a 2 meter yagi antenna

Thisis post 2311 in a continuing series of simple ham radio antennas. Thanks to "Prepping Ohio" for this tutorial on how to build a simple 3-element 2 meter beam antenna. The antenna is vertically polarized, allowing for distant repeat contacts. Most of the materials are available at the nearest hardware store or building supply outlet. Ihad used cubical quads for many years and the decision for 20 meters and up was easy, but what to do For 40 Meters? Some years ago I built a MOXON Rectangle antenna for 6 meters. The performance was excellent with good gain, great side and back rejection and seemed to work very well. Cost to build was very low and Construction was very easy. Connectyour antenna analyzer or SWR bridge. Adjust the driven element length outside of the trap equally on both sides of the element until it is resonant on 17 meters. Once it is resonant on the 17-meter band measure the overall length of the driven element. Reduce that length by 5% this will be the new length for the director. Forthose big boom antennas I came up with a novel twistI built a 60 foot boom 20 meter 6 element yagi. The element tapers and mounting plates were all computer designed (W2PV method) . The Omega match was built in an outdoor PVC electrical box with the two adjustments made by 1/4 inch aluminum rods along the boom to the mounting point. Vay Tiền Nhanh Cầm Đồ.
