Hi All

In the past 2 months, I have seen two different articles in ARRL
publications that say a vertical with 1 radial has gain in the direction of
the radial.  One said 3 db.  Evidently Eznec confirmed this.

Why the heck do I bother putting down all those radials under my verticals??
According to one article, 1 radial is best because it gives the antenna a
real wide bandwitch, SWR is close to 50 ohms, and has gain in the direction
of the radial.  Seems like those symptoms would give loss not gain.

Is this true, or is the ARRL just publishing anything now?  Sure is
different from anything I've ever known about verticals.

Seems like I should be able to put up an antenna with 1 radial on my rotor
and I could point it just like a beam.  Fill me in.  73
