(Professional Installation Recommended.)
Measure, mark, and locate an accessible and discreet area to run wiring through the roof and wall of the camper for the roof penetration and switch plate inside the camper. Also measure and mark for the location and hardware of the Wifi extender. It is best to make sure the area around the extender is free of obstructions for at least 12” in all directions. If possible, position the mounting hardware over structural components to help support and attach the equipment securely to the roof.
Make sure you will be able to get 12V DC to the new switch plate. (If there is a power jack for your TV antenna, you can catch 12V from there by positioning the new switch plate directly beside the existing one for the TV.) If prewired, you should already have a switch plate on the wall and cover plate on the roof.
Start with the opening for the switch plate, and then make the opening for the roof penetration so that you can fish the wiring down to from the roof to the switch plate opening. If pre-wired, you will only need to access the factory roof penetration. Make appropriate connections in the provided cables. The cabling wire should be coiled up below the roof penetration with the insulation in the “attic.”
Double sided butyl tape can be placed under the roof penetration adapter to help prevent any leaks where the hardware will penetrate the roof. Use butyl roof tape such as EternaBond to secure and protect the connection cable across the roof and into the provided penetration adapter.
For extra weather protection use Dicor non-sag sealant in any predrilled holes and around the wiring penetration prior to installing the penetration cover.
Finally, use Dicor self-leveling sealant to seal over all hardware and roof penetrations and to permanently secure the edges of the butyl roofing tape.
