Hi Rick It depends what you mean by "really short". Some consider a half wave to be really short. Beverage Rice and Kellogg original AIEE paper showed that there is not much difference in the pattern of a half wave and a full wave, but considerable difference when you go to 2 wave. They considered the half wave to be working as a Wave antenna, and for sure the ones I have used (6 ft or so above ground) had useful directivity on 160. 73 Bob VE7BS ----- Original Message ----- From: "Rick Karlquist" <[email protected]> To: "K4RO Kirk Pickering" <[email protected]> Cc: <[email protected]> Sent: Sunday, January 23, 2011 7:39 AM Subject: Topband: Do short beverages "work"?
