An antenna housing facilitates retrofitting a repeater/router and/or an LTE antenna on a vehicle. The combination antenna housing comprises a housing including a base adapted to be assembled to the vehicle, an intermediate portion, and an upper antenna enclosure portion for a radio and television antenna. A method for providing a vehicle with one or more communication links includes the steps of first assembling a plurality of cables within a wall of the vehicle that extend from inside the vehicle to a location on a roof of the vehicle. A radio and television antenna is attached to one or more of the cables within the combination antenna housing. An extra cable is secured inside the housing without electrically connecting the extra cable to another device until after assembly of the vehicle is completed.
