Redundant Master and Slave
Where the system requires a higher level of security, this scheme protects against the loss of the
GPS signal at one of the antennae, or a hardware failure in a master unit. Connections are as in
6.3.2.
6.4
Antenna
An easy-to-mount antenna is equipped with T-GPS3000A. The antenna should be mounted in an
open location with an unobstructed view of the sky.
The antenna has diameter: 100 mm and total height 180 mm. It is mounted on a rod having a
diameter of 32 mm; the antenna and its mounting kit are shown below, together with a picture of
the total assembly.
The antenna should be mounted in an open area where it can see the sky at an angle of 160 ° or
more. Take care that no buildings, trees or other obstructions can prevent a direct line to the
satellites, and cause the loss of the system synchronisation signal.
