- Page 3 Antenna Orientation The orientation of the antenna at the site is vitally important. In Horizontal configuration, the radiation is broadside to the antenna i.e. if transmissions need to travel in a predomi- nantly North-South direction, the antenna should be set up with the ends pointing East-West. Horizontal Configuration For Inverted V, the antenna becomes more suitable for NVIS, with radiation being directed at high angles, but omnidirec- tional around the antenna on a horizontal plane.
