How to Use Your VHF Marine Antenna for an AM/FM Reception
Extra antennas take up space and add expense. (boat radio antenna image by Sirena Designs from

The two most common electronics that require an antenna on a boat are AM/FM and VHF radios. The farther away from shore you get, the better antenna you need. Unfortunately, marine antennas take up space on your boat and additional antennas cost more to buy and install. When a boat already has a VHF marine antenna save space and expense by using it as an AM/FM antenna. Using it for radio reception is as simple as adding a frequency splitter.

Skill level:

Things you need

  • VHF antenna
  • AM/FM marine VHF splitter
  • AM/FM double-side male cable

  1. 1

    Unscrew the antenna's cable from the marine radio. Like a cable for a television, it should come loose with finger pressure.

  2. 2

    Screw the marine antenna to the splitter at the position labelled "Antenna."

  3. 3

    Connect the splitter's VHF plug to the VHF marine radio's input connector. Connect it according to the VHF radio's instructions.

  4. 4

    Insert an AM/FM cable with two male connectors into the splitter's AM/FM antenna output jack.

  5. 5

    Insert the other side of the AM/FM cable into the radio's antenna input jack.

Tips and warnings

  • Antenna manufacturers recommend using two antennas. Splitters work best for boaters who don't have the space for two antennas.
