I wouldn't mount it on the sides either. All my ZJ/XJs have them in the roof. I gutted the sunglasses compartment in the overhead console and then drilled right over it so the connector/mount comes in thru there. Cable is run forward to above the windshield, across to the A pillar, under the pillar trim down to the dash then under the dash to the radio. Not hard at all. Need a good solid antenna mount, a large washer for support under roof and a spring. I found a weaker spring actually worked better than the HD stiff one. Put less stress on the mount. However it did need replacing every other season.
