The paper I linked definitely describes a glide path controlled using Lorenz beams at a UHF frequency and it is the patent of 1937 to which my post referred.

Apart from distortion of radiation patterns by ground reflection it would produce an equi signal zone which is a straight line so it would lend itself to a descent as David YVM describes.

It would be interesting to find a picture of the antennas used for it - no success with that yet. Just a statement that they were separated vertically which only makes sense.
