The RF500B base station resides at the computer site and serves as a link between field stations and repeater stations. It includes an RF500M radio modem connected to a PS150 power supply. The modem and power supply are then mounted to a 10 inch by 12 inch metal plate. The radio, antenna, antenna cable, and wall charger need to be ordered separately. Compatible radios include our RF320 series, our RF310 series, our RF300 series, and the DataRadio DL-3400. Software support is provided by LoggerNet.
