 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
