You are right, it was a diplexer. Basically these provide a high impedance to the other transmitter while simultaneously providing a suitable impedence to the aerial for each transmitter (or frequency).
@celtickool I rather doubt it was done that way. I'm a broadcast engineer and I suspect what they were using was in fact a diplexer which blocks the signals from one transmitter from getting into the other but passes them onto the antenna.
I would have thought that switching between the transmitters at 50 times a second would have imposed a 50hz hum on the modulated signal it would be interesting to hear how this was dealt with

Excellemt presentaation; I have worked in radio-tv for 25 years myself. Have many transmitter installations. I even haven an AM-FM I look after!
