Marine HF Antenna Shore Installation

Marine high frequency, or "HF," radio does not require a direct line of sight between the antenna of the transmitter and the antenna of the receiver. This means that the height of an HF marine antenna isn't as important as it is for a very- or ultra-high frequency---VHF or UHF---radio signals, which require a nearly-line-of-sight route between transmitter and receiver. The marine HF antenna is an eight-foot pole wrapped with wire.

Things You'll Need

  • Post-hole digger
  • Duct tape
  • Torpedo level
  • 10-foot section of 1-inch steel pipe
  • Two 8-inch hose clamps
  • Screwdriver
  • Quick-setting concrete
  • Wheelbarrow
  • Shovel

Instructions

    • 1

      Dig a two-foot deep post hole, using a post-hole digger.

    • 2

      Tape, with duct tape, the top and bottom of a torpedo level to the approximate middle of a 10-foot section of steel pipe, so the body of the level is parallel to the pipe. Open two eight-inch hose clamps using a screwdriver.

    • 3

      Position the HF antenna on one end of the steel pipe. Slip the hose clamps over both the pipe and the antenna. Tighten the hose clamps to hold the base of the antenna to the steel pipe.

    • 4

      Pour the contents of a sack of quick-setting concrete into a wheelbarrow. Mix with water according to the directions on the bag. Stir, with a shovel, until the concrete begins to set. Shovel the concrete into the hole.

    • 5

      Set the end of the steel pipe without the antenna into the hole. Move the pipe to an upright position, according to the level taped to the pipe.

    • 6

      Hold the pipe stable until the concrete cures enough to hold the pipe by itself. Connect the coaxial cable from the radio to the base of the antenna. Remove the level from the pipe.
