AMC-RFCRFS001B - Nona-band RF Coupler For Smart Meter Remote Antennas

Universal ultra low-loss, nona-band RF coupler suitable for use with most brands of electric utility meters such as Elster, Itron, Landis+Gyr and GE Metering.

This RF Savvy series Nona-band RF coupler is an ultra low-loss, universal nine-band, stand-alone radio frequency coupler designed with a generic form factor suitable for use within the enclosure of most electric utility meters.

The 10kV electrical isolation enables safe routing of the RF signal from the NIC or wireless modem to a remote external antenna via a bulk head connection in the meter base (not supplied). Input and output RF connections are MMCX jacks (straight or right-angle) located either side of the PCB.
