Here’s a picture from page 167 of “Lockheed” by Bill Yenne

“the only way to get at the truth is to go back to the primary sources.”
Sorry, Ian, despite your comments about “the father of radar” and apparent dislike of him, pompous as he was, I still count his book as a primary source since he was intimately involved in all the initial developments and spin-offs from radar. Having said that, I do not claim to be an expert on the history of radar and must bow to your superior knowledge ( and presumably much larger library).
I hope I am not appearing too pompous myself! Perhaps it comes with old age, but I still reckon that given a set of CPN-4 circuit diagrams I could explain its workings, the training I received at RAF Locking was so thorough! Of course the GCA radar known as CPN-4 was American!
I expect you know that the motto of the Radio Training School at RAF Locking was in fact “Thorough”!

Yes, why is an advert taking up our valuable space in the prime position on the Historic Forum Web page?

The 10 cm wavelength meant that the scanner could be small enough to fit inside an excrescence (lovely word!) under the fuselage, hence H2S, e.g. on Lancasters. Previous radars had much longer wavelengths which required much larger scanners.

. . . The Super G Constellation came out in 1955
and featured weather radar and optional wing-tip fuel tanks . . .
