I've just been searching through my copy of Harmsworth - plenty there about aerials including full constructional and erection details for a 36ft. lattice mast at the far end from the chimney, but nothing as to the reason for the limit. I've always taken it to be aimed, as has already been said, at limiting the nuisance that could be caused by an oscillating TRF receiver.

In light of which it surprised me to find in Harmsworth a drawing proposing an aerial comprising four parallel 85ft. wires, with a 15ft. downlead to the house to use the rest of the allowance.
