Directional UHF antenna ZZ403

The ZZ403 base antenna is a directional antenna designed for the UHF band 420-470 MHz. The antenna is welded from aluminum alloy and protected by varnish. The antenna gain is 4.5 dBd, which corresponds to 6.65 dBi. For lightning protection, it is protected by a galvanic connection to the mast. ZZ403 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.
