Nate, as noted in the original posting, (below,) they've been at 404 MHz since
1992, and they're apparently wide enough to be taking out 406 MHz personal
locator beacons.
Granted, that would be a bigger issue for satellites looking down at radar
pointing up, but it'll probably still be "Son of Pave Paws."

Honeywell Wins Contract to Build 449 MHz Wind Profiler
PHOENIX, March 29, 2010 -- Honeywell (NYSE: HON) today announced that it has
been awarded a $49 million contract to upgrade the National Weather Service's
radar wind profiler network that will predict severe storms earlier and provide
the public with more accurate warnings of upcoming storms.
"For nearly two decades, ground weather radar improvements have been mostly
incremental - yet weather patterns and storms around the globe have become more
severe," said Vince Trim, president, Honeywell Technology Solutions, Inc.
"Honeywell is building a ground radar wind profiler network that can predict
severe storms earlier and more reliably while better able to withstand
hurricane force winds year after year."
Honeywell's work on the production phase of the Next Generation National
Oceanic and Atmospheric Administration (NOAA) Profiler Network contract
includes upgrading the NOAA network of wind profilers that provide upper air
wind data for crucial weather forecasting tasks.
The NOAA Profiler Network has been operating continuously since 1992 and the
equipment is now unsupportable. Honeywell's solution, which includes upgrades
to the antenna, RF hardware, signal processing, networking, and other system
components will provide the technology improvements to bring the profiler
network up to a supportable, maintainable, and reliable level. Honeywell will
change the radio frequency of existing 404 MHz profilers by replacing them with
449 MHz systems. This will prevent the existing interference with search and
rescue satellite-aided tracking transponders...
