Aerial Switches (the Organ Loft)

The output from the transmitters went via co-axial copper tubes to one of the two aerial Switch Rooms. These interior of these rooms looked like large church organs. The pipes came in horizontally from the transmitters to the switching decks. The aerials were then connected on vertical co-ax pipes up through the ceiling to the first floor, then at right angles again, stretching out across the roofs and eventually to the overhead open wire feeders to the aerials.

It was always wise to stay out of the Switch Rooms during lightning storms as blue flashes and static discharges could be seen jumping from un-terminated aerial pipes.
