The ZZ201 base antenna is an omni-directional (omni) antenna designed for the 150-175 MHz band. The antennas are
welded from aluminum alloy and protected with varnish. For lightning protection, it is provided by a galvanic connection. It is resistant to icing and wind up to 150 km / h. The antenna gain is 2.5dBd, which corresponds to 4.65 dBi. The coaxial cable is connected with an N-type connector. The antenna is durable, reliable and used in hundreds of applications.
