Simple and effective antenna for
160, 80 and 40- meter Band may be realized as an Inverted Vertical.
Inverted Vertical is differed from widely spread Inverted Dipole
just an additional wire. However the antenna is most efficiently
compare to the usual IV antenna. Figure 1
shows the design. The antennas may be made from copper wire in
diameter of 1- 2- mm. Instead of the mast may serve a tree or ever wall
of the house.
Antenna was simulated in
the MMANA and the parameters were simulated in the NEC for MMANA.
Antenna has good broadness at all of the bands.

Antenna tuned to the needed
frequency band by the length of the inverted vibrator. Counterpoises
may be placed at different place to the ground. Anyway File MMANA
and practice allows play with the antenna.
Figure 2 shows parameters of the RZ9CJ Inverted Vertical Antenna
for the 160 Band. Figure 3 shows parameters of the RZ9CJ Inverted
Vertical Antenna for the 80 Band. Figure 4 shows parameter of the
RZ9CJ Inverted Vertical Antenna for the 40 Band.
