A low wind load lightweight dual cylindrical reflector antenna with a novel feed for direct broadcast satellite TV reception

A low-coast, lightweight, low wind load, transparent antenna for DBS TV reception has been developed using dual parabolic cylindrical reflectors with a novel broadband small size feed. The feed is mounted on the main reflector or close to it. It is mechanically rigid and it does not cause any considerable blockage. The reflectors of the new antenna are easy to manufacture with a very high surface accuracy. They can be shipped and stored in a form of flat sheets. The new DBS TV reception antenna is easy to assemble and disassemble and has a simple lightweight mounting system that is easy to install. To reduce the weight of the new reflectors, several holes are punched in their surfaces. These holes also make the metallic sheets transparent. Punched reflectors are stable and not significantly affected by strong winds. The overall weight of the new Ku-band DBS TV reception antenna including its mounting system is less than 1 kg.
