[Scan-DC] UHF Antenna on Virginia Motorist Assist Vehicles

[David Schoenberger]

Recently I observed a UHF antenna on a motorist assistance vehicle on
I-95 in Northern Virginia (I think this was in Fairfax/Prince
William).  I don't believe I've ever seen this before; usually they
only have a low-band one (for comms with VDOT) and VHF-High one (for
comms with State Police).  Anyone know what they're using the UHF one
for?

Thanks,
Dave
