Part Number Description
VW-ANT-2-SMA VidiWire antenna system 2.4-2.5 GHz
VW-ANT-1-SMA VidiWire antenna system 1.7-1.9 GHz
The VidiWire™ antenna system was specifically designed for video transmission
from on-body transmitters. This DTC Proprietary system provides the best
possible omnidirectional video transmission from a body-worn system. The
system is composed of three parts: two special patch-type antennas, and a
phasing module.
WARNING: VidiWire Antennas are housed in a milled aluminum cover which
shields the wearer from RF energy. Make sure the antennas radiating side is
directed away from the body.
WARNING: Do not use the VidiWire antenna system on the body with any
transmitter outputting more than 250mW of RF energy.
COMPONENTS
WARNING: Refer to Appendix A of this manual for information on the proper
use of antennas.
