WebCPCs are static collectors with an involute reflective surface around a cylindrical reactor tube. They have been found to provide the best optics for systems with a low solar radiation concentration and can be designed with a concentrating ratio close to 1 for capturing both direct and diffuse UV sunlight. Webetc. Reflector systems are probably the most wgain antennas. idely used high-They can easily achieve gains of above 30 dB for microwave and higher frequencies. Reflector antennas operate on principles known long ago from geometrical optics (GO). The first RF reflector system was made by Hertz back in 1888 (a cylindrical reflector fed by a dipole).
