GPS amplifier & splitter

This unit is a combined GPS amplifier/splitter; it has a built-in line amplifier with a gain of 16dB that can transmit a GPS signal to up to three separate GPS repeater/receiver units.

This versatile device can be used in three main configurations:

  • As a GPS splitter unit (1:3) with the amplifier not used
  • As a GPS splitter unit (1:3) with the amplifier in circuit
  • As a line amplifier only with the splitter element un-used

Application Example

Waterproof (IP67) GPS amplifier/splitter unit

Roger GPS amplifier/splitter unit (IP67 waterproof)

For environments where dust and/or moisture ingress is an issue.

The IP67 amp/splitter specification is identical to the standard unit shown above; the only physical differences are as follows:

  • Size: 200 x 119 x 39mm
  • Weight: 243g
  • Enclosure: IP67
