The three latest FLEX units are dual-trailer outfits, with 53-foot expanding trailers (to 16’6” wide) for unit A, and 53-foot long (8’6” wide) for Unit B VMU trailers. The new dual-trailer units’ infrastructures are all based around the Grass Valley Kayenne K-Frame X IP switcher, an Evertz 384-port EXE 2.0 IP router and an Evertz Magnum control system, to offer 1080p capacity that would require at least a 3000×3000 baseband router.
 
Mobile TV Group is also building a 48 FLEX OB truck, which is a 53-foot expandable unit. It too will house a Calrec Artemis.
 
Mobile TV Group predominantly services the US sports markets, with units spread across the country, each run by around 50 engineers. The current count of 30+ mobile units, including 15 dual-trailer rigs (Unit A and VMU-Unit B) that can run the group’s ‘dual-feed’ production concept – operations for both home and visiting teams from two spaces but with shared technical resources.
