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.

 I choke everything.  If it's a wire, and it's near the antenna, it's a 
potential radiator.
 In fact, on my mobile installation, I had worse RFI/EMC problems with 
the 12V control wires to the tuner and the remote head cable for the 
radio than with the coax.
