In reverse order, I do not know who is currently making quad antennas commercially. Lightning Bolt made some fine models through the 1990s, but they went away several years ago. I ran a two element Hi-gain quad at 70 feet for 10 years from 1972 - 1982. With that antenna and my Swan 500CX, I was king of the hill whenever I operated on 10, 15, and 20 meters. Remember, though, this was before pairs of stacked 6 element beams were a dime a dozen, so the playing field was perhaps somewhat more level then than it is today. The common quad vs Yagi comparison that I have always heard is that a full size 2 element quad is at least equal to a full size 3 element Yagi in terms of performance. My experience with the 2 element quad, and with other 3 element beams before and since, confirms that statement to my satisfaction. Be advised, however, that a 4 element 20 meter quad is somewhat of a mechanical monster to keep in the air. ----- Original Message ----- From: "Ed Malmgren" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, May 02, 2011 5:28 PM Subject: Opinions? I would like some feedback about antennas. I have had tribanders and four element yagis and I have been thinking I would like to try a three or four element quad. have you any experience with both and what is your ideas. Also wich is a good brand? Thanks and 73 Ed K7UC
