Megahertz Ltd, a systems integrator and mobile broadcast production specialist, is using its IBC2015 presence to demonstrate its all-round engineering and problem-solving skills.
Featured on the stand will be a newsgathering vehicle, one of a series built for a major broadcaster, which imposed a slightly unusual challenge for Megahertz. For business reasons, the broadcaster wanted to use leased vans for the fleet – which means no holes could be cut or drilled into the base vehicle. After five years the van is returned in good condition to the lease company, and the equipment will be transferred to a new vehicle.
“It forced us to do a lot of engineering head scratching and intelligent application to come up with a solution,” recalled Jon Flay, managing director of Megahertz. “The racks and technical furniture are secured in the van using seat mounting points, and the satellite dish is mounted using roof rack fixing points.”
The broadcaster was also keen that the unit be as environmentally friendly as possible, so specified the capability of running the technical systems on batteries for six hours.
On the roof is a VSAT satellite link which can be quickly and easily switched between Ku-band and Ka-band. It is also fitted with a bonded cellular link and a terrestrial microwave antenna, so the signal can get back from almost anywhere. There is a small mast to lift the antennas above the traffic if needed for improved transmission.
