So, what is the first thing you do to a $60,000 truck? Why you drill a 3/4" hole in the roof of course!
Actually, I drilled two of these. That hole allows me to install a standard NMO mount:
And thus two permanently mounted antennas. One a wideband VHF, the other a dualband 900/1800:
The coaxial runs are pulled straight back so as not to interfere with the moonroof's travel. Couldn't get the camera in to get a pic but the runs are pulled behind a roof support. In order to drop the headliner down, this O.S. bar has to be removed:
Both runs are tied behind this panel:
And both cables terminated with RF connecters - a mini UHF for the Motorola CDM1550LS and an FME for the Wilson dualband wireless amplifier:
The control head for the Motorola is mounted in the console:
And the pickup antenna for the wireless cellular amp is hidden inside the center console:
The transceiver bodies are temporarily screwed to the back wall.
