GPS splitters are used so that multiple receivers can share one GPS antenna. The smart GPS Splitter shown above is a one-input, two-output device (1x2). This would be used for one antenna and two receivers. 1x4, 1x8, 1x16 and 1x32 splitters are also available.
- 1x2, 1x4, 1x8, 1x16 and 1x32 splitters are available.
- Rackmount chassis (1x8, 1x16 and 1x32 splitters)
- GPS L1 and L2 bands with excellent gain flatness.
- 20 dB minimum gain block (1x2). All others 0 - 4 dB.
- TNC connectors.
- One RF output is DC-loaded with a 200-ohm resistor to mimic antenna current draw.
- Ask about interconnect cables - various lengths are available.
Power Source Options
In the normal 1x2 configuration, one of the splitter RF outputs (J1) passes DC from the connected GPS receiver through the splitter to the antenna, allowing the GPS receiver to power both the antenna and the splitter amplifier. The other RF output (J2) is DC loaded with a 200-ohm resistor to simulate the antenna current draw.
Splitters are also available with external power supplies that provide the DC voltage to the antenna. This ensures GPS antenna availability regardless of the power-on state of devices connected to the splitter.
