Opek tech folded dipole
WebFolded dipole antennas have ends that turn back toward the center to help maximize the signal strength. Other options include the half-wave dipole, the folded dipole and the half-wave folded dipole. Advertisement Disadvantage: Size Although the indoor dipole antennas are usually small, the outdoor versions can be large and difficult to manage. WebDipole Antenna. Amateur Wire Antennas The Opek HF-BD1 is a broadband dipole covering 2 to 30 MHz. It can handle up to 150 watts. The VSWR for 2-18 MHz is 2:1 typical and 18-30 MHz is 3:1 typical. This antenna is 85 feet long and comes with 98 feet of 5D-2V coaxial lead-in cable terminating to a PL-259. 50 ohm.

The tips of the antenna are folded back until they almost meet at the feedpoint, such that the antenna comprises one entire wavelength. This arrangement has a greater bandwidth than a standard half-wave dipole.
