[TowerTalk] identifying Mosley antenna

[Bryan Swadener]

 Yep. I devoured Steve & Ward's book (http://www.championradio.com/shop/Publications.2).I like my Force12 C-4XL (C3 + EF240) that I found for cheep. It's a pretty good 'flamethrower'.
Equally significant is F-B and F-S rejection. It's nice to decrease QRM by turning it away from signals you DON'T want to hear. One day on 10m during a local round-table, I made an unscientific test. One fellow a few miles away ALWAYS ran a kilowatt. With the yagi aimed in his direction, his signal was expectedly VERY strong. With the yagi turned 180° away, his signal was significantly reduced. With the yagi turned 90° away, his signal was close to the noise.

You might want to re--think that. About 18 years ago, K7LXC and N0AX 
(ARRL Antenna Book and Handbook editor) set up and measured a dozen or 
so tribanders in the "small" and "large" category in a VERY well 
disciplined series of measurements. The two Mosley antennas came in dead 
last, and on some bands even had negative gain compared to a dipole at 
the same mounting location. The small antennas were a C3, TA-33, and a 
Gem Quad. The large antennas were a Pro-57B, C31-XR, Skyhawk, TH-6 and 
TH-7, TH-11, and KT-34XA.
