The company had originally planned to have the truck built by 2006/7 but, according to Omni, this was delayed owing to the later-than-expected tender process, coachwork slots and the requirement of a new finance lease. It should now be ready for action by mid-July.
The£3.7m truck will be the largest in the Barcud Derwen fleet, and expands to five metres wide.
It will be used to cover events such as the National Eisteddfod and Welsh domestic rugby.
Omni manager Tony Cahalane said: “We anticipate spending 50% of our time in Wales and the rest elsewhere in the UK or abroad.”
The truck will come complete with 24 HDC1500 Sony cameras. Installed on board will be a 576 x 576 Probel Cygnus router, a Sony G Series 8000 vision mixer and a Calrec Alpha digital sound desk.
The truck's other features include a greenroom kitted out as a small presentation studio for interactive or internet production allowing Omni to broadcast two different programmes from the same truck.
