Three Element Yagi Antenna for 145- MHz with Square Reflector

 

 

 

By: Yuriy Skutelis, RN3DEK

 

The antenna provides good F/B ratio. Antenna has input impedance 50- Ohm that allows fed the antenna directly through 50- Ohm coaxial cable.  It was reached by special form of the reflector. Figure 1 shows design of the antenna. Reflector of the antenna made of aluminum wire in diameter 4- mm. Elements of the antenna made of aluminum tube in diameter 8- mm. Boom of the antenna made from dielectric stuff.

 

Figure 2 shows input impedance of the antenna. Figure 3 shows SWR of the antenna. Figure 4 shows DD of the antenna.
