It may do. I have no idea if it is.
Would it work in areas where reception/signal is poor? Just as an example, the dip at Leazes Bowl has a terrible effect on the radios and that isn't too far from control. It isn't too exposed fortunately, unlike some of the far flung reaches of the A19.
IME, it's the Gilesgate roundabout that loses signal, particularly anticlockwise from Claypath, while the Leazes bowl is pretty consistent. Might be different for radio than phone, mind.
