Oh, fer corn sake. Not likely. The cable isn't theoretically shielded, it is
shielded. The leakage of the electric field? You mean the e-field of the
sub-microvolt GPS signal or the e-field of the three or four milliamps into the
antenna amplifier? Not likely. Not through a tinned copper braid shield.

More likely that the antenna has a steel mounting plate. Move the antenna or
remove the mounting plate.

-
-Move the antenna and you will observe the compass swing. Although the
-antenna cable is theoretically shielded (?), the leakage of the electric
-field affects the adjacent magnetic field, thereby affecting the
-magnetic compass.
