is widely used among radio amateurs. The antenna shows the efficiency
at several bands (as usual from 3 to 5) at minimal stuff to do
it. The described below antenna is a modification of the W3DZZ
Antenna. The antenna could work at 80- 40- and 15- meter Bands.
Figure 1 shows all steps to transform W3DZZ Antenna
to my design.
It is known that classical W3DZZ Antenna has traps
for one or several bands. In my case the traps were changed at
first to quarter wave stubs then the stubs were superposed with
antenna wires. I got compact and reliable antenna that worked
good at three bands- 80-, 40-, and 15- meters. Sizes of the antenna
at Figure 1 are given in centimeters. Stubs were
fixed with help of dielectric struts. Antenna should feed through
75- Ohm coaxial cable if it is placed at some height above the
ground. If the antenna made in the shape of inverted V the 50-
Ohm coaxial cable should be used for feeding the antenna. Antenna
was made from 2- mm (12- AWG) copper wire. Coaxial cable should
be placed at right angle to the antenna wires.
The Antenna was used for several years at UP2NV station
and it was showed a good result.
