EnviroMonitor Long Range Antennas
Long-Range Omni Antennas can be installed in conjunction with EnviroMonitor Gateways and Nodes to transmit data
over greater distances than the internal dipole antenna. Can be used Node-to-Node and Node-to-Gateway.
The 7676 Long Range Antenna is a standard 5 dBi omni-directional antenna; the 7678 Long Range Antenna is a
standard 8 dBi omni-directional antenna. Both come equipped with an integrated Reverse Polarity SMA Male
Connector which connects to the Gateway or Node.
Note: Customers outside the US and Canada are responsible for procuring their own long-range antennas that comply with local regulations.
