• Of all simple vertical antennas over ground, the 5/8 wave radiator has the lowest angle of radiation, however the base of the 5/8 antenna presents a relatively low impedance, not the high impedance offered by the ¼ wave stub. This suggestion is a flop. • The full-wave antenna is voltage fed, so it readily

Two factors that assist in obtaining wide-band performance on 70 cm are the addition of the fourth element and the use of an element diameter that is physically equal to the 2-meter element diameter. At 70 cm, the 1/8" elements are equivalent to 3/8" elements at 2 meters. In addition, we do not always add elements to a Yagi beam to obtain gain.
