dB Broadcast won a contract from Arqiva to supply and install the Programme Input Equipment (PIE) at 90 transmitter sites as part of UK digital switchover (DSO). Arqiva upgraded the entire terrestrial television infrastructure.

The first full switchover was at the Selkirk transmitter group in November 2008 and this was followed by the West Country.

dB supplied more than 550 bays across the 90 key sites. Prefabrication and testing was carried out at dB’s factory, and installation performed by dB’s in-house technicians. The project included approximately 500 Hawkeye frames with 3,000 modules, which included B080 series and B049 ASI monitor/switch modules and B102 DVB-T COFDM receivers.

dB Broadcast was also responsible for the onsite cabling from the sites’ incoming programme feeds to the inputs of the transmitters, and the installation of the IT network, remote alarm and RF monitoring infrastructure. This included RF, ASI and Ethernet cabling, some of which was fibre.
