Overview

The innovative DAB GAP-FILLER (On Channel Repeater) from UBS is the latest in the new product range being released to serve the DAB transmission market. This outdoor unit is completely self -contained; only requiring connection to the main power supply and receive and transmit antennas.

This very flexible unit provides the complete solution to the broadcaster dilemma of how to increase the coverage of the DAB signals in a cost effective manner.

Whether the unit is employed to increase coverage in an urban environment or provide coverage in a geographically challenged area, its performance is truly stunning.
This wide bandwidth unit receives the DAB transmitted signals, filters and amplifies them with a minimum of distortion, boosting a transmit power to 1, 4 or 10 Watts. This is achieved by using linear Class A amplification.

The DAB Gap-filler has a bandwidth of approx. 50 MHz. UBS offers a complete set of DAB Gap-fillers, which cover the entire L-Band frequency range. The user must specify the required frequency range or the DAB channel or group of channels, when ordering the Gap-fillers.

The primary application of the DAB Gap-Filler is the propagation of a seamless DAB COFDM signal, where geographical and physical impediments have affected network coverage, creating poor or non-existent signal reception (“gaps”). The Gap-Filler is engineered to eliminate network coverage deficiencies, by delivering the expected quality of signal reception to DAB receivers.

Being designed for outdoor, unattended operation, the unit is easily installed in a variety of locations (e.g. roof tops, utility poles or pylons and street lighting poles etc), keeping the cost of ownership to an absolute minimum.

As our world becomes more mobile, additional services come on line and greater coverage is required. This product will allow you to serve your customers in the most cost effective way, while keeping your capital costs to a minimum, hence offering the best possible opportunity for strong revenue growth.

The unit comes pre-configured and should require no further adjustment for most installations. The output power is monitored closely and is maintained at the set level, as long as the received signal is within the specified range.

The user can monitor the output power, internal temperature, received and transmitted signal levels, gain control values and alarms via a serial port connection.

Optional Remote Control

The Gap-Filler includes an optional SNMP remote control feature, supported by an additional processor and a GPRS/GSM cellular modem, included in the unit. This version of the product includes battery back-up for the processor and modem.
