The system operates on 12VDC vehicle power through an independent cab-mounted
switch. There are no speakers, microphones, or other vehicle tie-ins.
Nine VCA100 models are available to cover the LMR bands (see Table 1). The LMR
antenna must match the frequency band of the VCA100 model being installed. A
standard, roof mounted 2.4 GHz 802.11 antenna is used for all VCA100 models.
