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.

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.- Hide quoted text -

"The Beverage Antenna is a relatively inexpensive
but very effective Long Wire Receiving Antenna
used by Amateur Radio, Shortwave Listening (SWL),
and Longwave Radio DXers and Military Applications."

"A Beverage Antenna consists of a Wire one or two
Wavelengths Long (Hundreds of Feet at HF to several
Kilometres for Llongwave)."

"A Resistor connected to a Ground Rod Terminates
the end of the Beverage Antenna 'pointed' to the
Target Area, a 470 Ohm Non-Inductive Resistor provides
excellent results for most Soils {Locations}."

"A 50 or 75 Ohm Coaxial Cable Transmission Line
connects the Receiver to the opposite-end of the
Beverage Antenna through an Impedance-Matching
Transformer."

Three Characteristics of a Beverage Antenna :
* One or More Wavelengths Long
* Near the Ground Surface {within Several Feet}
* Terminated

Three Characteristics of a Longwire Antenna :
* One or More Wavelengths Long
* High Above the Ground Surface {1/4 WL or More}
* Not Terminated
ERGO a Non-Terminated Beverage Antenna
that is Rigged relatively High-Off the Ground
