There is presented 5 elements directional antenna for the 50- MHz Band. Antenna has good SWR at the band and excellent F/B ratio.

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 tube in diameter of 16- mm. Folded elements of the reflector made of tube/rod in diameter of 8- mm. The elements are inserted into main reflector as it shown in Figure 2. Dimensions are given in millimeter

The antenna has reflector with bent ends. It is done to improve F/B ratio. Anyway you may play with model of the antenna in MMANA and check what you could reach.
