[TowerTalk] Omnidirectional antenna for domestic contests

[Jim Brown]

Hi Herb,

I just modeled a 30M dipole at 50 ft with one leg rotated 45 degrees, 60 
degrees, and 90 degrees. Yes, the nulls fill some, but at the expense of 
broadside gain. And, of course, it's much trickier to rig, requiring 
four supports and/or guys in the good places. Two fans require four 
supports, but they can be widely separated.
