if you have a 1:1 SWR then you might expect poor radition effiecency. And
certainly if you get the vertical upwards of a 1/2 wave or so up, you start
generating vertical lobes and raising the angle of the horizontal lobes, so
don't put it up too high....73, Tim K8WBL
Hi Tim, I know you can have a dummy-load at resonance and perfect SWR, but
I never heard the analogy that 1:1 SWR could imply poor efficiency.
Pray-tell, how is this so?
