Cassegrain antenna YD-CA 4-600 It is a composite antenna consisting of two reflector surfaces and a feed. The rear-mounted feed design greatly facilitates system integration and has been widely adopted in the satellite communications field. This antenna can achieve 57 decibel The aforementioned gain can be achieved by modifying the feed characteristics to realize linear polarization and circular polarization radiation patterns.
