Directional UHF antenna ZZ403L

The ZZ403L base antenna is a directional antenna designed for the UHF band 390-450 MHz. The antennas are designed for TETRA and TETRAPOL networks. 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. ZZ403L 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.
