Introduction
A Grid Parabolic Antenna is a high-gain directional antenna that has a parabolic reflector built of a metal grid construction rather than a complete dish. This design enables the antenna to provide great long-distance signal transmission and reception while lowering wind resistance and weight.
Grid parabolic antennas are commonly employed in point-to-point (PtP) and point-to-multipoint (PtMP) wireless communication systems, particularly for outdoor and long-range RF applications.
What is a Grid Parabolic Antenna ?
A grid parabolic antenna operates on the same principles as a solid parabolic antenna. Incoming RF signals are reflected by the parabolic grid surface and directed toward a feed element located at the focal point. The grid layout lets air to travel through, making the antenna suited for windy outdoor conditions.
