What is an antenna hub

Antenna hub - what is it for?

The antenna hub is used for mounting an aftermarket car radio with input for 2 antennas, but there is only one antenna in the car. Antenna splitters with an amplifier are also often used. The antenna splitter can be used, for example, to use a VHF antenna to receive AM and FM signals for car radios when using a VHF antenna. Suitable for cars with an original car antenna.
