Well you can use a Beverage antenna for SW as well. I might
have to put one across the way here in a few days when I get
some more material.
The idea of a Beverage is to have a multiple wavelength
antenna. Multiple wavelengths on SW frequencies are much
shorter, and many longwires are, in essence, possesing those
properties already.


- No that would not be correct. - A Beverage is a special case
antenna - different from long wire antenna. - - -- - Telamon -

A Beverage is a specific kind of long wire, generally wavelength or
multiples, which can operate well low off the ground (MW Beverages
are often on sticks in the ground) and is grounded at one end and
end, not center, fed. Like other antennas, they can be used in
multiples to create directional patters and "moving" directionality
by means of a phasor.


It doesn't have to be grounded at one end, though it can be, to
reduce reception off the back end of the wire. In that case the
ground should be at the end reception is desired from.

The longer the wire (in wavelengths) the greater the gain and the
greater the directionality with respect to the direction(s) the wire
is running.


Good response DxAce.
