Hi Darrell,
The initial Venues were a little less sensitive than the 411's, as
measured here, by several dB (80% of the range). That correlated with
feedback from the field and our own walk tests. Keep in mind, that the
Venue includes the added front end noise of a built in distribution
amp (there ain't no free lunch). Small changes in the Venue PC board
layouts, involving the placement of vias and transmission lines, has
wiped out most of that deficit. A 411 running by itself is still
slightly more sensitive but a 411 used with a distribution amp is
essentially equal to the Venue.
Sensitivity is important only if you are in a very quiet RF
environment. Fewer and fewer areas now qualify as RF quiet. As an
example of the trade offs to be made in design, the tracking receivers
(Venue VRT and UCR411's) are usually not as sensitive as the non
tracking units (Venue VRS and UCR401's) due to filter losses in the
narrower front ends. However, the improvement in RF rejection of the
tracking front end is more than worth the small reduction in
sensitivity when receivers are used in an urban area or in a bag
system.
If I were deciding which way to go, I'd balance the flexibility of
separate 411's against the cost savings, packaging of the Venue and
the computer interface. Sensitivity would be a minor factor. Also keep
in mind, the failure of a major system in the Venue brings the whole
system down. Separate 411's are just that. And to flip flop the other
way, you can buy a backup mainframe with the Venue and still be money
ahead.
Best Regards,
