Thie Beverage discussion is quite illuminating. It seems then that the
Beverage works well over a wide range of ground types but does not work (as a
Beverage) over very good ground or very poor ground.
Is is a cross between a quasi-TEM t-line and an antenna?
The polarization is 100% vertical on axis and is tilted off axis. Broadside
the polarization is 100% horizontal.
I experimented in NEC with an additional wire running under the Beverage.
With the wire grounded things were not too bad. Connecting the added wire to
the
Beverage, as a two wire Beverage, did not work well at all.
If anyone has very good ground or very poor ground and would like a
"Beverage-like" radiation pattern contact me for information on the TTLLCCA.
Mechanically it is similar to a Beverage - same height and length yet is not
affected
much by the ground under it. The polarization is predominantly vertical on and
off axis.
