How to make a folded dipole antenna for 6 meters
(PhotoObjects.net/PhotoObjects.net/Getty Images)

A dipole antenna is a simple design that's easy to build and effective within certain frequency ranges. The folded dipole variation of the antenna employs wires that are folded back upon themselves for a more compact antenna. When constructing a dipole antenna, the starting point will always be the frequency, or wavelength, the antenna is designed for. A 6-meter dipole antenna will operate best at 51MHz, useful in many VHF applications.

Instructions

  1. 1

    Remove 1/2 inch of insulation from both leads on both ends of the twin-lead cable, using a set of wire cutters. Twist together the two wires on each end. This creates a closed loop of wire.

  2. 2

    Cut one of the twin leads in the centre of the wire loop. Strip away 1/2 inch of insulation from each side of the cut wire.

  3. 3

    Screw two wood screws halfway into the wood block, separated by 1 inch. Twist the bare wires from the centre of the wire loop, one around each of the screws.

  4. 4

    Slide the U-shaped connectors onto one end of the transformer under the heads of the screws, one under each screw. Tighten the screws until they're flush with the wood block.

  5. 5

    Plug one end of a 75-Ohm coaxial cable into the other end of the transformer. Plug the other end of the cable into your receiver.

  6. 6

    Suspend the antenna from the middle and ends at the highest location possible for the best reception.
