I am building a 2 element mini beam (yagi) for 20 meters. Should the second element be a director or relector for more gain? I live in a low QRM nieghbor-hood. Tlhanks for your suggestions and input. Jack - KW5JC |

You can typically get more gain with a director. But, if you want to cover more than a small part of the band, you may want to go with the reflector for a higher matching impedance and more bandwidth. http://www.qsl.net/dk7zb/start1.htm This page has some designs--he suggests using a director on the narrow WARC bands and a reflector on 10/15/20 meters.
