[Towertalk] 100M-long boom Yagi for 20M

[af4mp@mindspring.com (Zyg Skrobanski)]

A typical broadcast curtain array will have a gain of 21 dBi with a
bandwidth of about 10°.  I guess that's why super long Yagi's are not used.
 I'm waiting for some fancy contest outfit to come on the air with their
own beam curtains!
