Product Description

The GS14 and GS14i GPS Splitter are intelligent power selection devices with one-input and four-terminal outputs, which are designed for wireless base station applications.

The main application is to share GNSS antennas and used as ordinary RF power dividers.

GS14 type GPS Splitter

GS14i type GPS Splitter

GS14-S type Power Splitter

GS14-S utilizes an aviation power plug for power supply, which both to internal devices and GPS antenna.

The wiring method for the aviation plug interface:

Step 1: Connect the A-end to the Positive pole of the power supply,

Step 2: Connect the B-end to the Negative pole of the power supply,

the C port is a reserved wiring port with no function.

The power supply voltage range is 12V~28V. Power consumption is＜0.5W.

Packing & Delivery

Packing Process

Firstly, the splitter are individually wrapped in plastic bag.

Secondly, the splitter with plastic bag will be put into a small box (box size: 12.5*10*3.5cm).

Lastly, a big carton will be used to pack all the small boxes, which is strong enough to withstand rough handling during transportation.

You may rest assured that, if extra packing demand is required, we'll try every means to meet your requirement.
