Fabricated backing/ground plane brackets for the GPS and GPS/XM antennas. Drilled mounting/access holes in the cabin top for the two antennas. Fabricated and ran the two antenna cables for the GPS/XM unit. I still have the 650 GPS antenna cable to run. I was hoping to get all three cable through the forward support bar but I suspect there won't be adequate clearance around the top mounting bolts. It that doesn't work, I'll run the cable down one of the A pillars.
