helix vs. Loop



Clare's (VE3NPC) helix article in the AMSAT Journal (May-June 2006) is to me one of the best researched and best written articles on helix antennas. Of the many questions researched, It deals with the turns vs. gain and PVC usage questions in which everyone seemed to have a varying opinion.
   
  There are advantages and disadvantages to each type antenna
   
  Here are some helix info websites.
   
  1.http://www.qsl.net/ve3cvg/antennas/
  Good antenna website plus 2400 MHz helix.
