70 MHz Antenna Projects

Amateur radio antenna designs for 70 MHz band

70 MHz antennas are specifically designed for amateur radio operators to operate on the 4 meters band. These antennas provide efficient transmission and reception capabilities for hams, allowing them to communicate effectively over this frequency range. With various designs and plans available, hams can choose or build antennas that best suit their needs for reliable and clear communication in the amateur radio community.

  • Vertical half-wave aerials for 4m
    This project details three variants of a vertical half-wave antenna design for the 4-meter (70MHz) amateur radio band. The antennas use end-feeding with a parallel-tuned circuit for impedance matching to 50-ohm coaxial cable. The first variant uses suspended flexible wire for portable use, the second employs a fiberglass rod with internal wire for permanent outdoor installation, and the third utilizes aluminum tent poles for quick mobile deployment. Despite the narrow bandwidth of the matching circuit, this suits the narrow 4m FM allocation well. The design offers an effective omnidirectional radiation pattern and can be constructed with readily available materials.
  • 70 MHz Moxon antenna
    This article describes the construction of a Moxon rectangle antenna for the 70MHz (4-meter) amateur radio band. This compact two-element beam design features folded element ends, reducing its width to approximately 75% of a half-wavelength. The antenna was built using enamelled copper wire stretched over a lightweight fiberglass kite spar frame, with a direct coaxial cable feed connection. Initial testing showed a VSWR of around 1.3 with distinct nulls at 90 degrees when horizontally mounted. The author later tested vertical polarization and suggested that the antenna's compact size might allow for indoor loft installation.
