12m actually. The transmitters worked between 20-50mc but were used
mainly around 23-30. Amusing now to look at the S-27/36 covering only
to 144 or so and seeing it labeled as 'Ultra High Frequency' heh.
Chain Home Low was actually up in the 200mc realm. They even had Chain
Home Extra Low, can't remember if it was 400 or 600mc?

.Lotsa BIG towers, receiving towers were generally wood IIRC. When I
was looking into this stuff back in the 90s, there were only a few
(2-4?) of the metal towers left standing and I think one was coming
down soon due to rust. I hope they manage to preserve at least one,
such a legacy for the Brits.

Not sure if this is it, but The Battle of Britain from 1969 had some
shots like that, big board surrounded by a balcony with girls in
headphones sliding numbered blocks around to illustrate where enemy
aircraft were in what strength, and groups scrambled to intercept. My
favorite aerial flick, as they went out of their way to be accurate,
down to buying surplus Spanish Messerschmitt 109s and renting Spain's
HE-111s (albeit re-powered with Merlins) for the air combat scenes.
Plenty of Spits and Hurricanes as well. Nice re-creations of the
coastal radar stations too.

One site I enjoyed visiting was called CHiDE or had that in the title.
Great folks who would answer questions and even email a specific shot
if needed. There's another called Subterranea(n?) Britannica with tons
of info including floor plans and copious amounts of photos. Also
several good books, all of which escape me at this point due to the
late hour. I remember one had a shot of Chain Home transmitting towers
on the cover, and I think one may have been called 'Wizard War' or
similar. If I remember, I'll look for them tomorrow and send you the
info. Right now, it's off to cut some z-z-z-z-zs.
