The MHX-910A is a frequency-hopping 900 MHz spread-spectrum communications module providing the industry’s most robust and cost-effective means of providing embedded long-range data communications between industrial serial communication devices. 

This unit is modular certified to a full 1W, where other competitors fall short of a watt of power, thec gives long range performance unlike any other modem.  This unit is both FCC and IC approved at the modular level for quick integration. 

The MHX-910A can be ordered with a HV (High Voltage) option which allows an input of 8 to 30VDC and RS232/485/422 level or can be order in 5V TTL levels.
