XPDK-S Super Triad
 The
XPDK-S-300/500 synthesized diversity receivers
offer optimum capability to overcome picture breakup
and color distortion in applications where the
transmitter or receiver are in motion. They can
be used with any transmitter within their operating
band set to the same frequency and deviation.
The XPDK operates by using multiple receivers
and antennas to look at and evaluate a single
transmitted signal. The theory is that one of
the arriving signals will be better than the others.
The best signal will be selected and automatically
switched to at over 15,725 times per second. In
addition, antennas may be routinely mounted 100'
from the receiver rack, enabling the agent to
position the antenna around obstructions.
The XPDK-S series combines either three or five
receivers in a standard 19" rack, and is
ideal for command post or surveillance van mounting.
Multiple camera systems are supported in the
MegaCam™ configuration, shown in upper right.
Antennas are often shared between rack receivers
by using customized antennas spitters.
Features
- Designed for rack mounting in surveillance
van or camper top
- Multiple receiver architecture, either 3 or
5 receivers installed
- Automatic receiver switching during horizontal
interval
