I'd take it you would usually use the mast before getting a let down with Leeming LARS to the west?
Anything low level in the vicinity of the mast would most likely have gone through the Leeming gap and be on the way out. No?
How far away you could get a fix is limited by your height agl and the terrain between you and the fix. That’s why masts were so handy - they stuck up above the terrain. How far off track? Tornado GR radar swept maximum of 60 degrees either side of heading. Vulcan H2S had a 360 deg sweep, and there was consternation amongst the Nav Radars when Flixborough chemical works blew up in the 70s!
