Just thinking outloud here... but is there such a thing as a CB repeater? Something you could setup at your home to help bounce CB radio signals around?
We have them for our business band farm radios, and with the two repeaters about 10 miles apart, we can use handheld two ways about 10 miles away from any repeater... We can use the pickup and tractor mounted ones about 30 miles away...
I found the answer, its not legal on the CB band, but can be done.

Sec. 95.419 (CB Rule 19) May I operate my CB station transmitter by remote control?
(a) You may not operate a CB station transmitter by radio remote
control.
(b) You may operate a CB transmitter by wireline remote control if
you obtain specific approval in writing from the FCC. To obtain FCC
approval, you must show why you need to operate your station by wireline
remote control. If you receive FCC approval, you must keep the approval
as part of your station records. See CB Rule 27, Sec. 95.427.
(c) Remote control means operation of a CB transmitter from any
place other than the location of the CB transmitter. Direct mechanical
control or direct electrical control by wire from some point on the same
premises, craft or vehicle as the CB transmitter is not considered
remote control.
