7 VHF channels

Hello all,

This thread is far from boring!

Someone mentioned earlier that the maximum number of VHF channels
in a given city would be 7. I assume that those channels would have
to be 2, 4, 5 or 6, 7, 9, 11, 13. Is that correct?

In case anyone is wondering, I have evidence of an actual case where
channels 4 and 5 are used, and sharing the same antenna as well!
The big diplexers are quite something to behold!
These two channels are separated by a guard band of 4 MHz, so they
can coexist in the same area, and at the same time they are close
enough that the same wideband antenna can be used (66-82 MHz)
These two channels are in use as described above in Quebec City.
Does anyone know of a similar installation elsewhere?
