The Shakespeare AM/FM - VHF Marine Band Separator 4357-S works with all types on marine VHF antennas and eliminates the need for a separate AM/FM antenna.
Will not interfere with VHF radio performance, and allows both the AM/FM and VHF radios to operate at the same time. It's automatic, so no switching is required when transmitting on the VHF radio.
Supplied with a PL-239 Connector and instructions to join the Marine Band Separator and VHF radio. Supplied with 10' of RG-62 cable with Motorola Plugs to connect AM/FM Radio and Marine Band Separator.
