Extending the number of repeaters by 
adding an Amplifier/Splitter 

ROGER™

 GNSS Amplifier& Splitter(GNSS-AS)       

ROGER™ G

NSS Amplifier & Splitter is a combined 

signal splitter and line amplifier with an output of 
+12dB (1 port) and +4 dB (2 ports) that can 
transmit to up to three separate repeater units.   

In order to get the amplification, the ports must 
be connected as shown below. The unused ports 
must be terminated with a 50ohm termination if 
less than 3 repeaters are connected to GNSS-AS.

 

 

Extending the number of repeaters by 
adding a Splitter 1 to 2 

ROGER™

 GNSS Splitter 1 to 2 (GNSS-S2) 

With the ROGER™ G

NSS Signal Splitter 1 to 2, the 

signal from one external antenna can be 
redistributed to up to two repeater units. 

It is advisable to use a separate amplifier with the 
signal splitter to ensure adequate transmission 
power to all the two repeaters. If the signal is to 
be transmitted to only one repeater, the unused 
port must be terminated with a 50ohm 
termination. Splitter is powered through the 
output signal cable by the 

ROGER™

 GNSS 

Repeater and it passes on DC power for the GNSS 
receiving antenna or GNSS line amplifier.
