      HG>Hi Tom,              HG>HG>TW>The Create CLP-5130-1N LPDA antenna has Transmit capabilities for 50 t       HG>HG>TW>1300 Mhz with a SWR of 2:1 or less              HG>HG>Yes, a real LPDA can be made to cover almost any frequency span.              HG>TW>And no matter the implimentation, Double boom or Single boom with       HG>TW>insulated elements and crosssover wiring it is Still a Real LPDA              HG>Nope, a real LPDA always has two booms and the feed is connected to the       HG>front of the antenna with the braid to one boom and the inner conductor       HG>to the other boom.              HG>The front of the antenna is of course the end of the antenna with the       HG>shortest elements.              Well on the antenna I am talking about the shortest elements are at the       Front and ALL elements are driven by the coax.              And when one web serches the picture of BOTH types show up as       LPDA antennas. The twin bom antennas is called a "Real World" LPDA       becasue it is much easer to construct.       But Both use the same Theory and give the same Results       ---        þ SLMR 2.1a þ Typo Tom Strkes Again        * Origin: Fidonet Since 1991 bbs.docsnetservices.com (1:123/140)    |
