Although the leaky feeder (rather than base-station) approach will
defuse that argument immediately.

Do leaky feeders of the length that would be required work at 1800Mhz?

For possibly the third time, they work elsewhere. In any event, you can
segment a leaky feeder if total length is an issue.

(There was also a plan to have them in the Channel Tunnel, but I suppose
the business case wasn't sufficiently made. There's also an
International Roaming issue to solve, and iirc they declared one tunnel
to be UK and the other to be France. Similar issues apply to Microcells
on an aircraft, how high off the runway does it have to be in order to
start charging at roaming rates, rather than UK?)
