So I decided to install on my backyard the design of
Two Wires Beverage Antenna with Two Wires Open Line. It allows
me eliminate industrial noise from home electrical equipment receiving
by vertical parts placing near my home. Of course, the antenna
was installed with taking into account local conditions and final
design was far away from the classic one. Figure 3
shows my Two Wires Beverage Antenna. Two wires line from the feeding
end going athwart to antenna wires. It was possible to me in the
antenna design and allows eliminate the noise receiving by the
vertical part of the antenna from the home electrical equipment.
Two wires line on the antenna end was placed at some angle to
the antenna wires because there was no such strong electrical
noise in the place. Shape of my antenna was close to diamond not
to rectangle.
The antenna and two wires open line was made from 16-AWG
strand Black wire in plastic insulation. The wire is used for
Ground Wire in the electrical job. For some unknown for me reason
the wire is very often on sale (in small coils on 20- 40 meters)
in my local Home Depot Store that gives me some stuff for my antenna
experimenters. Two wires open line going from the transformer
to the antenna wires has 450 Ohm wave impedance. Figure 4
shows design of the line. Pieces of PCB were used for struts in
the line. Figure 5
shows picture of the two wires line. Two wire line going to the
termination load shows in the Figure 6. The line has wave impedance close to
800 Ohm. By the way the value of the wave impedance for the two
wire line at the antenna feeding terminals and at the load terminals
did not connected with Beverage Antenna input impedance and value
of the termination load.
