EZ-AIR
Radiomodem with integrated antenna. Outdoor applications, IP65 protection
EZ-AIR is a simple / half duplex 868 – 870 MHz radiomodem with coaxial dipole antenna embedded. The integration of the radiomodem with the antenna greatly improves the efficiency of the system by eliminating any connection loss. The use of a RS485 interface with a presence of an extended range switching power supply (8 to 32 Vdc) allows extremely long cable without functionality limitation (47 mt @12 Vdc, 180 mt @24 Vdc with standard cable).
