For a receive-only setup, you could easily run the 315/433MHz control
signal up the coax, along with 12V DC power and the returning signals
from the Beverages. A few inches of wire threaded under the shield braid
at each end of the coax (like the old Monimatch) should make a good
"launcher" and "catcher", and the coax link should deliver far stronger
signals than over the air between antennas.
