GPS antenna is used to capture satellites, receiving satellite positioning information, that is, radiating and receiving electromagnetic waves; any high-frequency circuit, as long as it is not completely shielded, can be more or less to the surrounding space Or electromagnetic radiation, or more or less received electromagnetic waves from the surrounding space, so it is widely used; then where is the GPS antenna usually installed? What should you pay attention to?
1, landing installation
Floor mounting can be used for wider platforms, but GPS antennas and cable bridges should be kept as close as possible to avoid signal reflection. Note:
(a) Separate the antenna and cable bridge by at least 2 m. If it is difficult to separate, raise the antenna so that it is at least 2 m away from the bridge;
(b) Install the antenna on the daughter's wall wherever there is a parapet.
2, the tower installation
Most towers or areas with low-rise buildings are installed with iron towers. Tower installation recommendations:
(a) The GPS antenna should be installed on the south side of the tower;
(b) The GPS antenna should be as far as possible from the tower, at least 2m;
(c) Do not set the GPS antenna too high, and ensure that the cable length is as short as possible.
3, postal installation
(a) The antenna should be slightly higher than the post, and the post should not choose the tip of the post to reduce the chance of inductive lightning;
(b) Don't be too tall for antennas and poles to avoid becoming the highest point in the area.
4, the daughter wall installation
(a) Install the GPS antenna on the daughter's wall as much as possible at the location of the parapet;
(b) It is best to choose the daughter wall in the south (for the northern hemisphere);
(c) The GPS antenna should be made 1 to 2 m above the parapet wall.
