This high quality Aerpro Antenna Kit comes fully equipped in a pack that includes a 477MHz elevated feed antenna (6dBi Gain) and two whips (65cm and 15cm).
Where can you use it?
The elevated feed antenna is a ground independent design that performs very well in alternate mounting locations. While mounted, this allows an omni-directional coverage pattern, whether on little or no ground plane at all. It is designed to function without a ground plane while elevating the antenna's radiation point high above obstructions.
