Nigel re post #55 - that installation is indeed a VHF/405 installation, most probably around mid 1960s. I can't quite make out whether the Band I "H" is a dipole-director or dipole-reflector version but, in any case it would have been for BBC1. The ITV aerial is an horizontally polarised Band III "double" with a slot feed. It may well be a J-Beam "double six" which has moulted a couple of bits. Horizontal polarisation was not so common in the VHF TV era being reserved mainly for relays and just the odd main station.

The UHF aerial at the bottom is more recent and looks like some no-brand cheap rigger's special.
