A VHF marine antenna gets its name because it is used to broadcast transmissions from water. Therefore this type of antenna is commonly used in boats. If you have a little free time on your hands and are interested in a project, you can actually make your own antenna rather than buy one.

Instructions

  1. 1

    Use the wire stripper portion of your wire cutters to strip an inch off the end of the coaxial cable and expose the internal wiring.

  2. 2

    Run the wire through the front of the UHF connector so that the wiring from the cable sticks out of the end of the connector.

  3. 3

    Use your soldering iron to solder the coaxial wiring to the end of the UHF connector.

  4. 4

    Strip 39 inches off the remaining end of the cable sheath and plug the UHF connector into the port on the back of your receiver.

  5. 5

    Run the remaining exposed length of cable through a piece of 29-inch PVC pipe and tape the end of the wire to the PVC pipe. This will be the antenna.
