All- Metal Three Element Antennas for the 145- MHz Band

Second of the files contained a wide known Hentenna Antenna. The antenna is not sensitive to nearest objects. Antenna elements maybe make from a length of a strand aluminum wire or a copper tube. Parameters of the Hentenna Antenna are better compare to the antenna UA0SNM.

Figure 11 shows design of the antenna. The antenna may be made of a copper tube or stranded aluminum wire. Diameter of the tube or wire may be 6- 12- mm. Figure 12 shows impedance of the Three Element Hentenna Antenna for the 145- MHz Band. Figure 13 shows SWR of the Three Element Hentenna Antenna for the 145- MHz Band. Figure 14 shows DD of the Three Element Hentenna Antenna for the 145- MHz Band.
