For a trunk-mounted VTac installation, the M-803 is
installed without a user interface. Instead, as many as
five Control Head units at locations throughout the
vehicle provide remote control for all radio functions.

VTac includes a duplexer for Full Duplex operation
and a voice repeater to provide off-network scene-of-
incident coverage.

In short, the VTac supports a rich array of radio
communications features, including:

•

 

All M-803 voice and data radio functions,

•

 

Network Extension support for portables in weak
coverage areas or in-building use,

•

 

Scene of Incident support for voice-to-voice off-
network communications,

•

 

Full Duplex operation,

•

 

Up to five control heads and one mobile data
terminals.

The OpenSky M-803 is the
core component of the
Vehicular Tactical Network.

Your VTac radio will
perform all the best
functions of the M-803
plus additional coverage
enhancements.
