The truck can operate with the expand in or out which Arena chief executive James Bonnar insists makes it perfect for the capital.
“If the driver passes a lamppost he can pull in the expand automatically,” he said. “I believe this makes it unique in this country.”
The truck, which cost£1.5m to build excluding cameras and the VT system, benefits from 12 Sony HD cameras, 12 Sony HD VTRs, a Calrec sound desk, a Pro Bel router and a Sony MVS8000 vision mixer.
It was used for the BBC's Electric Proms in October where it was parked on Liverpool Street, a part of London that - according to Bonnar - would not have accommodated a double expanding truck.
As well as one-off events, the truck will be deployed for Setanta's coverage of the Premiership, a contract that runs for another 18 months.
It is one of three OB vehicles that the company has commissioned this year. The others are an HD double expanding truck and a large VT truck which the company will take delivery of this week.
