It'd be a proper relay receiver.
The BBC used modified Revox B261s for their emergency backup chain for about 20 years (David owns and has restored an ex BBC example). The hops were 40-60 miles, but were in mono and they had good aerials on tall masts. Nevertheless, the signal was pretty grim by the time it got to northern Scotland.

This was actually activated in anger for several hours about a decade ago when a combination of human error and aircon failure took down the standard Nicam distribution system, which is supposed to be multiply redundant.

I think they use satellite backup now.
