The World Wide Radio Operators Foundation (WWROF) is pleased to present the following Webinar.
Date - Tuesday, February 13 Time - 19:00 UTC Registration - https://register.gotowebinar.com/register/6004189296300531458 Jukka OH6LI shares a presentation about receiving antennas. Gain and front-to-back are well established specifications. Some have used Receiving Directivity Factor, RDF as a receiving antenna metric. Now we have also the DMF. The Directivity Merit Figure algorithm is shown in an Excel tool for the first time. The Receiving Antenna Metrics Excel workbook is EZNEC and MMANA compatible. Presentation includes new metrics Noise Margin and Leaking Index. A number of antennas will be used as examples. The examples begin with residential area level solutions, extending to staggered beverages and beyond. Please note that this presentation will be recorded and available for playback at your convenience on the WWROF webpage: http://wwrof.org/category/webinar-archive/ 73 Ken K4ZW _________________ Topband Reflector Archives - http://www.contesting.com/_topband
