Beverage Antennas are widely used at commercial and
military radio communication. In commercial communication Beverage
Antenna as usual is used as a receiving antenna.
However, in military communication Beverage Antenna is
used for both purposes- for receiving and transmitting applications.
Transmitting/receiving Beverage Antenna was used in DX- Pedition
EK1NWB on to
Kizhy island (the antenna described at: http://www.antentop.org/008/ua3znw008.htm)
where the antenna (against skepticism of some persons) illuminated its
So when again in Toronto I have changed my QTH and
the QTH allowed me install Beverage Antenna, I did not hesitated.
Beverage Antenna has lots advantages that attractive
me. First, it is low noise receiving
antenna. At all my previously settled QTHs I had so devastated
noise level that 160 and 80 meter Bands were closed for me. Second, Beverage Antenna is lighting safety
antenna because the antenna wire grounded from both sides and
the antenna wire is placed at small height above the ground. Third,
Beverage Antenna is sustained at strong winds and ice rain- it
is very important for Canadian winter.
Forth, Beverage Antenna is (at proper installation) practically invisible.
That is very important in the place where some antennas may be
restricted. Fifth, Beverage Antenna is very broadband
antenna. Without any ATU the antenna may have good SWR on all
amateurs HF Bands from 160 to 6 meter. Sixth,
Beverage Antenna has single lobe diagram directivity. It is possible
count again and again the advantages of the Beverage Antenna.
But we begin count disadvantages. First and the main lack of the antenna is
the low efficiency on to transmission. However, the lack may be
easy improved with PA- but if you do not hear anything (usual
matter in modern city overloaded by electromagnetic smog) you
do not need PA…
Figure 1 shows a Classical Beverage Antenna. Beverage Antenna consists of a horizontal wire with length L. The length
may be from one-half to tens wavelengths long. The wire suspended
above the ground at height H. For real receiving antennas the
height may be from 1.5 up to 5.0 meter. For military transmitting
Beverage Antennas the height may be from 0.5 up to 1.5 meter.
