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:

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

Standard non-waterproof (IP51) GPS amplifier/splitter unit

Application example

Waterproof (IP67) GPS amplifier/splitter unit

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

Other components in the range can be combined with the amplifier/splitter to create a custom-designed system.
