The ZZ205 directional basic VHF antenna is designed for the 150-174 MHz band. The antenna is welded from aluminum alloy and protected by varnish. The profit is 6.5 dBd, this corresponds to 8.6 dBi. The beam angle in the H plane is 80 °. The beam angle in the E plane is 50 °. For lightning protection, it is protected by a galvanic connection to the mast. The antenna withstands winds up to 150 km / h. ZZ series antennas are durable, reliable and used in hundreds of applications.
