The National Association for Amateur Radio Web81K views 8 years ago Building the ultimate 2 meter ham radio beam antenna with local parts. The fact that it was only four feet off the ground would have little effect on the tuning, although the overall performance would be affected by the high angle of radiation. I havent experimented with the reflector length yet to see the effect on the gain and the front-to-back ratio. In this project author explains how to A two element 10-Meter beam designed for portable or permanent installation.

And although its somewhat directional on the higher bands, I havent figured out how to rotate 200 feet of wire without the neighbors becoming suspicious. Magazine. 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 then enter the lowest SWR point (resonance) at the appropriate X-Y position. Locate your antenna as close as possible to your radio room to prevent loss of RF energy. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This Blog is mainly dedicated to Amateur Radio (Ham radio) and contains external articles and personal esperiences. Because the 1-inch section was going to be the center part of the two elements, I picked up U-bolts and nuts while I was there.
