The ZZ83 directional base antenna is designed for the 70-84 MHz band. The antenna is welded from aluminum alloy, protected by varnish. It consists of 2 parts for easier transport. The antenna gain is 4.2 dBd, which corresponds to 6.45 dBi. The beam angle in the H plane is 120 °, the beam angle in the E plane is 70 °. For lightning protection, it is protected by a galvanic connection to the mast. ZZ series antennas are durable, reliable and used in hundreds of applications.
