An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?
The correct answer is B. patch. Mine shafts are long narrow corridors, you would get more use out of a patch antenna as you don't require signal in all directions and the gain increase to reach further down the shaft.
