RRL Stations come standard with an omnidirectional antenna. The antenna should always be mounted on the outside of any enclosure for maximum communication distance, as they communicate via line-ofsight transmission. 900 MHz radios can communicate over distances up to 20 miles (30 km). To maximize communication distances between RRL Stations, an optional High Gain Antenna is available (pt# 108987).
Before sourcing any other power accessories or antennas to use with RRL Stations, refer to the radio module manufacturer's product manuals for approved devices at: http://www.digi.com.
