Good advice on all counts.

Mobile installations are particularly problematic, because the 
body/chassis is used as a counterpoise for our antennas, bonding of body 
and chassis is often flaky (or non-existent, thanks to paint) and the 
routing and design of interconnecting cables for vehicle systems pay 
little of any attention to EMC.
