SD-125EL V2 148-174 MHz

The Maxon SD-125EL Series of data/telemetry radios are designed to meet the needs for a variety of wireless applications in a cost effective package.

The modules incorporate the most requested mechanical footprint and connectors. Adjustable transmit power settings from one to five watts provides the power needed on any job and the LED indicator gives instant on-sight status of the radios operation. The die cast aluminum cabinet/lid provides resistance to RF interference; and gives exceptional environmental durability in the most extreme conditions. The SD-125EL can also be configured with POCSAG for paging applications.
