Think of a flat aerial as a double sided satellite dish - it transmits and receives towards both of the flat sides, not off the edges. A stick on type aerial on the side of the cockpit windscreen will give good reception to both sides but minimal ahead or behind. A pole type aerial mounted vertically will give reception in 360 degrees provided there are no metal objects nearby blocking signal.
