7 Installation

7.5 Mounting the GPS Antenna

The GPS satellites are not stationary but circle round the globe in a period of about 12 hours. They can only be

received if no building is in the line-of-sight from the antenna to the satellite, so the antenna/converter unit must

be installed in a location from which as much of the sky as possible can be seen. The best reception is given

when the antenna has a free view of 8

◦

angular elevation above horizon. If this is not possible the antenna should

be installed with a mostly free view to the equator because of the satellite courses which are located between

latitudes of 55

◦

North and 55

◦

South. If even this is not possible problems occure especially when at least four

sattelites for positioning have to be found.

The antenna/converter unit can be mounted on a pole with a diameter up to 60 mm or at a wall. A 45

cm plastic tube, two holders for wall-mounting and clamps for pole-mounting are added to every GPS164. A

standard coaxial cable with 50 ohm impedance should be used to connect the antenna/converter unit to the

receiver. The maximum length of cable between antenna and receiver depends on the attenuation factor of the

used coaxial cable.

Up to four GPS164 receivers can be run with one antenna/converter unit by using the optional antenna diplexer.

The total length of one antenna line between antenna, diplexer and receiver must not be longer than the max.

lenght shown in the table down below. The position of the diplexer in the antenna line does not matter.

High voltage protectors must be installed directly after entering the indoors. The optional surge protection

kit is not for outdoor usage.

Note:

If the antenna cable was assembled by the user: before powering up the system, make sure that there is no short-

circuit between the inner and outer conductor of the antenna cable, because this could cause a fault of the GPS164.

WARNING:  DANGER TO LIFE BY ELECTRICAL SHOCK!
Do not carry out any installation or maintenance work on the 
antenna system or cabling when there is a potential risk of lightning.

Make sure to comply with the occupational health and safety 
standards when installing the antenna. Never work without a proper 
fall protection device!

7.5.1 Assembly of the GPS antenna surge protector

Optional a surge voltage protector for coaxial lines is available. The shield has to be connected to earth as short

as possible by using the included mounting bracket. Normally you connect the antenna converter directly with

the antenna cable to the system.
