・Covers both Iridium® satellite frequencies and GNSS L1 band frequencies, and provides a solution for satellite communications indoors
・Use optional OPC-2462 (59 m, 193.5 ft) or user supplied coaxial cable (Max. 169 m, 554.5 ft) to obtain a line-of-sight path to the satellite
・Power over Coaxial (PoC) carries electrical power through the coaxial cable
– Electrical power cabling can be reduced
・Separate TX/RX unit configuration, TX unit with a Power Amplifier and RX unit with a LNA (Low Noise Amplifier)
・The main unit has IP67 waterproof and dust-tight protection for outdoor installation
