DVB-H Gap Filler (on channel repeater) DVB-PDX-1675/5/50/100

Features

Frequency range: 1660 - 1685 MHz
Available output power: 1, 4 and 10 Watts

Overview

The innovative DVB-H Gap-Filler (On Channel Repeater) from UBS is the latest in the new product range being released to serve the DVB-H 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 DVB-H 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 DVB-H transmitted signals, filters and amplifies them with a minimum of distortion, boosting a transmit power of 1 Watt. This is achieved by using linear Class A amplification.

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