Teko Telecom Service Front End (TSFE) is the Master Unit RF interface towards a Service Antenna: it provides wireless signal to the area to be covered.

Service Front Ends are driven by Teko Telecom Digital Donor Front End Modules: Modular Off-air Repeaters can be set-up by proper combination of Donor Front Ends and Service Front Ends.

Three different output power classes are available: Medium (TSFE-x-M), High (TSFE-x-H) and Very High (TSFE-x-V).

A single-band single-operator modular Off-air Repeater can be set-up combining a Digital Donor Front End Module and a Service Front End. Up to 4 Donor Front End Modules can be connected to a single Service Front End subrack to provide a single-band 4-operator Repeater.

The High Power and Very High Power Service Front can also be used in Optical Systems to provide coverage to the area adjoining the Master Unit site: auxiliary ports are available to drive the Optical System.
