Summary
[edit]DescriptionSternwarte Bochum Antennen.jpg |
Deutsch: Sternwarte Bochum
English: High gain satellite communication antenna, Bochum, Germany. It consists of multiple turnstile arrays, on a steerable altazimuth mount so it can be pointed at the satellite. Each consists of two Yagi antennas mounted perpendicularly on a common boom, fed in quadrature (90° out of phase). It receives circularly polarized radio waves, which are used by satellites since unlike other polarizations they are insensitive to the relative orientation of the transmitting and receiving antennas. |
