Mostly because it wasn't used in Chain Home or Chain Home low, which were HF and VHF rather than centimetric.
Plus it was invented in 1940.
None of the kit shown seemed capable of producing the sort of power levels (300kW?) that were mentioned.
You need big valves (really big valves) for that power level.
And it cooks you if you're not careful with it.
One of my physics lecturers (I forget his name) used to tell us stories of working on the early radar stuff. Apparently on a cold morning, they'd go out and warm their hands in front of the things.

Mrs IJNTTI got nabbed there as well last year.
It's still a source of amazement to me seven years later that I never got done driving London-Swansea and back every week for nine months. It seems every bridge over the M4 in Wales is populated by a man in a camera van.
Cockett Road in Swansea being the place where I got my first ever speeding ticket in 2011 after 30 driving years with nothing. 34 in a 30, Sun Morning, damn the Heddlu.....

Sort of drama-ed up the drama for suspense & I'm not convinced the implied timing of events was exactly accurate, but it filled an otherwise tedious hour & a half.
And I didn't fall asleep, which I usually do with Horizon these days.
