There is presented 3 elements directional antenna for the 50- MHz Band. Antenna has good SWR at the band and excellent F/B ratio. Antenna allows to be made with some tolerance. It is very convenient for because in real life it is very hard to note all outer environment objects. Antenna has 50- Ohm input impedance that allows feed the antenna directly by 50- Ohm coaxial cable.

Figure 1 shows schematic of the antenna. Antenna elements made of aluminum tube in diameter of 30- mm. Dimensions are given in millimeter

Figure 2 shows Z of the antenna. Figure 3 shows SWR of the antenna. Figure 4 shows DD of the antenna (antenna placed at 17.5 meter above ground).
