This is a recent install I did on a 2010 Ford Explorer. It has 5 BC15x, 1 BC996 a Vertex 3200 and a Radio Shack handheld.
With all those antennas wouldn't it have been more practical to have used a Stridsberg MCA208M Active Multicoupler. That would have given you 8 connections off a single antenna.
My thoughts exactly, to many antennas, to many holes in the roof that much more of a chance for a leak when it rains.
Properly installed NMO mounts do not leak, period. Just sayin'. To the OP, nice install!
