Quantity :

The ESTeem Model 195H industrial wireless router is the perfect radio solution designed for the rigors of the Industrial, Public Safety, and Federal markets when the VHF band is needed for terrain coverage.

These narrow band-compliant VHF radios operate in the 217-220 MHz frequency band and provide Ethernet, Serial RS-232C, RS-422, RS485 and 4 Channel Sensor Interface in a single wireless modem. The 195H industrial wireless router can cover distances greater than 10 miles in high noise environments depending on the antenna used. For added flexibility, the 195H is downward compatible to the ESTeem Model 192M/MHP series. You can create wireless networks over large geographical areas by using the internal Digi-Repeating feature, which makes all remote locations possible repeater sites.
