Antennas : 20M : 20 meter Vertical Antennas

  • The Vertical Buddi Beam for 20m - The Vertical Buddi Beam on 20m using no Coils. n this article I am going to describe a totally new way to construct and use a very old design the two element Yagi antenna. Unlike the traditional Yagi this design does not require a Tower or a boom, it is 100 percent portable and most important high- performance and easy to assemble using standard Buddipole components.

Antennas : End-Fed : End Fed Half Wave Antenna
  • End-Fed Half-Wave Antenna for 20m 40m 80m - How to Design and Build a Field Expedient End-Fed Half-Wave Antenna for 20m, 40m and 80m. This Shorty 80m EFHW comprises a 49:1 autotransformer (to match the very high impedance at the end of a half-wave wire), a half-wavelength wire for 40m (also a quarter-wavelength for 80m), a loading coil and a short tail wire. The coil and the short tail wire (about 6 feet) make up the other quarter wave on 80m.

Antennas : Mobile
  • An automatically tuned 7-30MHz mobile antenna - This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.
