I was thinking that the inside antenna would not connect via wireless to any radio but would be able to use any radio and maybe the signal would come through the outside antenna to the inside antenna then any radio could get reception wireless.
Large metal shop, is there anyway to put a pass through antenna.
Example: put AM/FM radio antenna outside and connect to
antenna inside the shop to receive signals inside the shop for
all people to have good reception.
This might be a silly question.
Thanks in advance for any advice.
