That's the thing I always wondered - it's one thing hiding a van on a residential street, another thing entirely hiding a crane with a load of antenna on top. Maybe commseng can help explain, but how exactly did they get the signal out from the target street? Maybe a low power link to a crane a couple of streets away / other side of a field that could then boost to a proper mid-point? Or were targets chosen based on whether they could get a link out without needing height?
And not only that, but once the tech team had hid and placed the cameras, wired them up, and (somehow, which is the bit I'm still struggling with) powered up and got the cables out of the targets room and to the OB van, they then had to get the signal back to TVC.
That van with its taped up MCR dish, must have been 'hidden in plain sight' for a good couple of hours before the start of the live programme.
The team must have pretty good at poker face excuses when the enviable 'tap on the window' came every so often for the curious local residents.
Bear in mind that the van was not branded with the BBC logo - of any vintage - but "Satellite Data Systems".
The excuse given was that there was surveying work going on to offer a new data delivery and that random areas were selected.
That was vague enough for most curious folks, and the "satellite" dish that was pointing towards the horizon rather than to the sky was not remarked upon.
Cables leaving the van towards a house were more likely to lead to questions, but they could be deflected, although obviously a few guessed what was really going on. Why spoil the surprise though?
Getting the cabling into the room was obviously the more difficult bit, and that would have been part of the survey.
Must have been a lot more wooden window frames back in those days that could be adapted.
