ZZ203 is a directional antenna designed for the band 150-175 MHz. The antenna is welded from
aluminum alloy and protected by varnish. The gain is 4 dBd, which corresponds to 6.15 dBi. Lightning protection is provided by a galvanic connection. The coaxial cable is connected using an N-type connector. ZZ203 is resistant to icing and wind up to 150 km / h. Antennas are durable, reliable and used in hundreds of applications.
