S14WI - 1x4 Wireless GPS Splitter


The GPS Source S14WI splitter has a rugged design and can be used to monitor the current of the GPS antenna. Users will be notified if the antenna is not working according to the specifications.

The S14WI is highly configurable and supports a wide range of optional features. For example, the DC bias “Pick & Choose” circuit allows it to apply the active antenna DC input to the RF outputs. One DC input will be used to power the antenna and if it fails, the DC bias will change to another DC input automatically so that the antenna will continue to operate.

Users can configure the gain value of the S14WI according to the need of their applications. It also supports an optional GPS filter on the input, which will greatly reduce interference from other sources. Furthermore, The sealed housing of the S14WI allows it to work in rough environments.
