1.3 The instrument is taken in high quantities
Using the auxiliary height gauge, the bottom of the antenna is selected by means of measurement
2 Receiver field work requirements
Precautions：
1. The distance between the station mode, the base station scaffold and the station whip antenna
scaffold is recommended to > more than3mto avoid interference with satellite signals by radio stations.
2. The reference station should be located in a higher terrain, open field of view, to avoid
high-voltage lines, transformers and other strong magnetic fields, in order to facilitate the transmission of
UHFwireless signals and satellite signal reception, network mode also need to pay attention to the operator
network coverage of hypothetical points.
1. Radio mode, if the mobile station is far away, also need to add a radio antenna lengthener.
2. If the reference station is mounted on a known point, to do a strict alignment.
3. The connection between the power cord and the battery should be red, black and negative to
avoid short circuits.
4. When the station is working, make sure to connect the external antenna, otherwise long hours
will cause the sending signal to be absorbed by the station itself and burn the station.
5. When connecting cables, note the connection of LEMOhead red dots to red dots.
6. Working in GPRSmode,GPRS traffic per hour is around 0.5M-1.5M(related to the number of
satellites and network environment).
The illustration of the installation of the external radio station of the base station is as follows:
