Im not sure, but its probably been dicusssed already. Ive not been closely following SkyNews Brexit coverage from outside Westminster in the last few weeks. But i noticed that Kay Burley and her guests are, have swapped their lapel mics for handhelds seemingly in order to cancel out the protester noise in the background. Never understood why they all persist in using those lapel mics in these situations. Also those (dead rat) mics with the big gray furry wind cover on them.... How good are those in blocking unwanted back ground noise, besides wind noise?
They swapped to the handheld mics midway though the Kay Burley show today after the lapel mics they were using caught too much of the inappropriate language coming from the protesters. I've not noticed them use them any other day, but then I haven't really paid much attention so I may be wrong.
The trouble with television news is lapel mics are the norm, so they're reluctant to change them even when they should. The prefer to avoid mics being out of shot as much as possible, in any form. It wouldn't surprise me if they didn't carry with them the more directional handheld mics until recently.
I myself wondered originally why the channels have stuck with The Green given how rowdy the protesters have been getting. However thinking about it, it's a very convenient place to get MP's for comment very quickly as all the chaos is happening, so I imagine they're going to stick it out.
