[Elecraft] What Vertical Antenna Do I Need?

[Stuart Rohre]

Yes, in theory any vertical half wave that is center fed should have the 
feeder run at exactly a right angle, but in practice, Force 12 provides a 
support arm for the coax, and that is sufficient to bring the coax off a 
couple of feet where it then can hang either parallel or at an angle to the 
vertical and we noticed no interaction at all.
