RF Integration
Careful design is required to minimize the interference. UNDP-1 performance parameters,
such as receiver sensitivity and transmitter spurious signals, should be evaluated to
confirm adequate grounding and shielding, location of the UNDP antennas, and perhaps
even placement and routing of other host computer functions. This evaluation should be
performed for all UNDP-1 operating bands.

Antenna considerations
As mentioned in
, the location of the antenna elements is critical to UNDP-1
RF performance. Routing the connecting coaxial cables could also impact UNDP
performance; they should be routed away from corruptive noise sources (like the
switching-mode power supplies, LCD assemblies, microprocessor, memory, etc).
