The ZZ401 base antenna is an omni-directional (omni) antenna designed for the 420-470 MHz band. The antenna is welded from aluminum alloy and protected by varnish. The antenna gain is 1.5 dBd, which corresponds to 3.75 dBi. For lightning protection, it is protected by a galvanic connection to the mast. ZZ401 is resistant to icing and wind up to 150 km / h. The coaxial cable is connected with an N-type connector. The ZZ series antennas are durable and reliable and used in hundreds of applications.
