The antenna polarity is Linear (parallel to the elements, perpendicular to the
boom).
4.1.8 Parabolic reflector antennas
A parabolic reflector antenna consists of a parabolic shaped dish and a feed
antenna located in front of the dish. Power is radiated from the feed antenna
toward the reflector. Due to the parabolic shape, the reflector concentrates the
radiation into a narrow pattern, resulting in a high-gain beam.
The antenna pattern is a beam pointed away from the concave side of the dish.
Beamwidth and antenna gain vary with the size of the reflector and the antenna
construction. Typical gain values are 15 to 30 dBi.
The antenna polarity depends on the feed antenna polarization.
