Figure 3 shows input
impedance for
rectangular
for the 40-meters Band. Figure 4
shows SWR
for rectangular for the 40-meters
Band. Figure 5 shows vertical and horizon
patterns. All
diagrams made by MMANA for
the Rectangular
designed for 7.050-MHz,
placed at height
of the 2 meters above the
real ground,
vertical parts of the antenna
- aluminum
tube in diameter 10- mm (000-
AWG), horizon
wires- aluminum wire in
diameter of
1-mm (18-AWG).

MMANA file for the antenna made by UR0GT.
It is possible
to design directional antennas
on the base
of the Rectangular. Reflector and
director may
be designed on the base of the
rectangular.
Such directional antennas may
be designed
for all amateurs HF bands.
Parameters
of Three- Elements Antenna made
on the base
of the Rectangular elements are
almost equal
to parameters of a Four
Elements Antenna
made on the base of linear
wires (YAGI).
