TECHNICAL PRODUCT DATA SHEETRMS18 SPLITTER
Rack Mount 1x8 GPS Signal Divider

DESCRIPTIONOPTIONSThe RMS18 Rack Mount Splitter is a one-input,eight-output GPS signal divider. Typical use is wherean input from a single active GPS roof antenna is split
evenly between eight outputs to create an indoor GPSsignal distribution network. The RMS18 is typicallyconfigured with a variety of power options: 110, 230(Euro) or 230 (UK) AC options and 12-24VDC or 48VDC where voltage is passed to the antenna input
port in order to power an active GPS antenna on thatport. In this scenario, the RF outputs (J1 - J8) wouldfeature a 200 DC load to simulate an antenna DC
current draw for any receiver connected to those ports.

The RMS18 splitter comes with many available options tomeet specific needs. Please contact GPS Source via
phone, fax, email, or visit the website for further
information on product options and specifications.
