GPS Power Splitter
GPS Power Splitter |
|
The passive Power Splitter 4443 is used to split the antenna signal
into two equally strong signals to reduce the loss while operating two hopf
GPS systems at one antenna to a minimum. The power splitter also
serves to uncouple the long-distance supply of the voltage to the central
conductor of the antenna.
The Power Splitter is set into a HF-proof housing with an insulated base plate. The unit can therefore be easily screwed to the wall near the GPS systems. The antenna must be connected to the single BNC-connector called "Antenna in". On the opposite side of the housing there are the two antenna outputs to the GPS-systems.
The smallest loss of power is achieved if the cables are of equal length after the splitting. Due to the special strip-line structure of the splitter an non-symetrical operation is also guaranteed. The permissible length of cable is the combination of the length up to the power splitter and the length to the GPS system. These lengths should not exceed the measures given in the list of technical data.
Please avoid not connecting the device to anything. This may lead to synchronisation problems in the rest of the system if the maximum length of cable is used. The free output must be closed by an HF-resistor of 50 Ohm.
It is also possible to connect a different GPS-system to a free splitting output. Please make sure that the external power supply of the antenna must not exceed 5 V DC and that the strange device also requires the original GPS-signal in L1-band.
