The simple 4- Element YAGI Antenna for the 20- meter Band has
very stable parameters. Antenna has SWR less the 1.1:1 at 14.0-
14.35- MHz. Antenna has input impedance 50 Ohm. The
antenna may be made of aluminum tube in diameter of 30- mm. Antenna
has high gain, and very easy for tuning. Design of the 4- Element YAGI Antenna for the 20- meter Band is shown on
Figure 1.
