MHX910A-HV-LITE - Professional OEM Wireless Module

900MHz Lowest Cost Complete Serial Wireless Communications

The MHX-910A-HV-LITE is the lowest cost ready to install 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, the gives long range performance unlike any other The MHX-910A-HV-LITE is the industry's lowest cost, "ready to install" 900 MHz frequency-hopping spread-spectrum communications module. It provides the most robust and cost-effective means of providing long-range data communications between industrial serial devices. The MHX-910A-HV-Lite is FCC and IC modular certified to a full 1W, which gives long range performance unlike any other modem. It allows for an input of 8 to 30VDC and RS232/485/422 level communication drivers for quick integration.


Why Choose MHX910A Product? 

The MHX910A-HV-Lite gives the longest possible range in the toughest RF environments. Our very low noise figure and extremely high interference rejection allows our transceivers to receive the weakest possible signals. Your installation costs will be reduced, due to shorter tower heights and lower gain antennas. 

These radios are ruggedized communication equipment built to blast through the toughest environments for noise, interference, vibration, and other 900 MHz products. Do the test for yourself and put any other radio beside our radio and see which link is the best.

Our cost is the most competitive in the industry. Each unit can be configured as a Master, Repeater, or Remote unit. All options are included in the price and there is no extra software required.
