most mobile installs have common mode currents on the coax due to the fact that the groundplane is not optimal.
its just inherent in using a car as a counterpoise.
my guess is that since you now have a long piece of coax going into the garage instead of a short piece that stays within the vehicle, that these common mode currents on the coax are your problem.
the way to get rid of them is to use about 6 inches to a foot of ferrite right at the base of the mobile antenna.
that being said, ferrite on the device that is receiving the interference usually works quite well.
