The simple 3- Element Broadband Antenna for the 145- MHz Band has very stable parameters. Antenna has wide passband that makes the antenna not critical to implementation and to near environment. Antenna has SWR less the 1.5:1 in 11- MHz passband and SWR less the 2:1 in 21- MHz passband

Design of the 3- Element Broadband Antenna for the 145- MHz Band is shown on Figure 1.

The antenna may be made of wire in diameter 1-- 3- mm (not critical). Antenna has high gain, does not require adjustments.

Figure 2 shows Z of the 3- Element Broadband Antenna for the 145- MHz Band. Figure 3 shows SWR of the 3- Element Broadband Antenna for the 145- MHz Band. Figure 4 shows DD of the 3- Element Broadband Antenna for the 145- MHz Band.
