My antenna switches have looked similar to a wall electrical outlet with a small push button to switch between air/cable. Have an LED that illuminates when in antenna mode.Usually located in an overhead cabinet. Usually located in the overhead cabinet side wall, not the outside coach wall. Often hard to see without a flashlight. Locate your roof top antenna crank handle, then look in the overhead cabinets near the crank.
