I think Knickebein and its successor Bernhard actually worked at about
30MHz, the antennae were about 30m high. Pre-magnetron British radar
antenna were up to 100m high.
I dunno what the OP knows/imagines is classified. I think most people who
actually have access to classified literature tend not to post about it on
All the best
