Eclipse Repeater/Base Station

The ECLIPSE range is a state of the art Base Station/Repeater system.

Eclipse Repeater/Base StationFollowing an extensive survey of user requirements, high reliability and superb performance were combined with many unique features to produce a superior, user friendly product. 

Fully integrated 100% duty cycle, 25 – 100 watts base/repeater stations in the range from 66MHz to 900MHz. Various configurations of racks are available including floor saving wall mount cabinets.

Exceptional systems performance.
Modular construction with independent Receivers and Transmitters. This allows split RX and TX racking for convenient connection to multicouplers etc.
Easily configured for Duplex, Simplex, Trunked or link applications.
Exciters can be used alone for 1-25 watt applications.
Separate High Power Amplifiers can be added for 25-150 watt output.
Transmitter power adjustable over a wide range to meet local licensing requirements.
Synthesized design with programming by IBM compatible PC through front panel RS232 port on each Receiver and’Transmitter.
100 channel capacity.
Individually programmable CTCSS with squelch tail elimination for each channel.
Programmable processor controlled repeater hang time.
Internal links for flat or emphasised audio response.
Wide Receiver and Transmitter frequency spreads.
The 19" rack module positions can be simply coded to automatically select channel and CTCSS tones.
All modules mate with readily available D range connectors.
DCS compatible without modification.
