- | hi, english test page | + | ====== Requirements provided to locations of installation ====== |
+ | |||
+ | The "Viewnok" complex consists of an antenna complex and a workstation completed with receiving equipment connected by a single coaxial cable. | ||
+ | |||
+ | Antennas must be installed on the roof of a building or in any other location with the best possible view of the sky. Buildings, trees, superstructures and other objects, narrowing the horizon, make data receipt more difficult. | ||
+ | |||
+ | Antennas require installation of two pipe stands (or two brackets with vertical mounting pipes), with a pipe diameter in the range of 25 ... 55 mm, being intended to mount the antenna. | ||
+ | |||
+ | The distance between pipe stands shall be equal to 1....2.5 meters. Pipe stands must be grounded according to the roof grounding regulations applied for antennas (usually - by means of a copper conductor with the diameter of at least 6 mm). Two corresponding conductors, each having the length of 1.5 m, terminated by means of a ring terminal and M6 screws, are included in the kit. | ||
+ | |||
+ | The antenna amplifier is mounted on a stand of one of the antennas. There is no need to power the antenna system (to provide low-voltage phantom power for the amplifier, since it is fed through a dedicated coaxial cable). Drawings of the antennas are given in Appendix 1. It must be possible to connect the antenna complex and workstation by means of a cable. | ||
+ | |||
+ | Allowed cable lengths and parameters of different cables are given in the table below. | ||
+ | |||
+ | {{:en:table_2.png?550|}} | ||
+ | |||
+ | The 5D-FB cable is supplied with the default length of 50 m. Other cable lengths and cable types are available based on a corresponding request. | ||
+ | |||
+ | By default, the cable is supplied terminated with one N-type connector. Upon a corresponding customer request, the cable can be supplied in a non-terminated or double-terminated form. When mounting the cable, the terminated end must be located on the antenna side. | ||
+ | |||
+ | The workstation installation requirements are the same as normal requirements provided for a personal computer installation site. The possibility of grounding the lower end of a coaxial cable is required above the determined standard. |
