Fiber Optic Converter for Antenna

Makes your antenna connection long and surge safe

Why fiber to the GNSS antenna?

The reason fiber is being used to connect GNSS antenna is consumers insatiable desire for be 100% resistant for overvoltage. In some cases mounting GNSS antenna on the roof of skyscraper means more cables up the tower. If those cables are coax, or signals require DC power this is not simple to do due to loses. Beside coax GNSS antennas are mostly prefab cable assemblies since making terminations is difficult and requiring special connector cramping tools. Also long coax cables seriously increases cost of installation. They are high diameter, and that is requiring skills and tools to mount due to angle limitation and risks of breaking/cutting cable that cannot be soldered again.






The ELPROMA Fiber Optic (FO) Converter can be used to connect  GNSS MulitSAT receiver to Elproma Timeserver. The max. connection distance is 1.5 km (1 mile). Single antenna requires 2 converters:

Doble redundant antenna system (ANT1, ANT2) requires 4 converters (2 on server side, and 1 for each antenna receiver).


FO-conv requires 24VDC. Unit #1 can be powered directly from NTS timeserver antenna connector (RJ45 PoE) located at back panel (label ANT1 or ANT2). Unit #2 is connected to GNSS MultiSAT Ant/Rcv and it is requiring external power supply. It is strongly recommended to use separated from main IT hardware 110/230V AC electric circuit. Since fiber optic is not caring electricity, using separate 110/230V AC powering (or solar panels) for GNSS MultiSAT Ant/Rcv makes solution 100% resistance for surge and overvoltage.
