The antenna has SWR less the 2.0:1.0 at the frequencies from 112 up to 165- MHz. Gain and pattern belong to the antenna are almost similar to a vertical lambda/2 dipole. The antenna has three resonance frequencies at the working band (112- 165- MHz). It explains why the antenna is such broadband.


Design: Two aluminum tubes, each is in 16-mm diameter, are placed in parallel plane with vertical shift compare to center each other. Crosspiece between the tubes made from a 50- Ohms coaxial cable. The crosspiece is in the plane where the tubes located. Figure 1 shows the design of the Avia Antenna.
