Vertical Antenna Pattern

The Little Stick Antenna – The Little Stick antenna is an aluminium version of the Vertical Bazooka design which was made from coax. The basic antenna The most basic antenna is called “a quarter wave vertical”, it is a quarter wavelength long and is a vertical radiator. Optical Analogies to Beam(Directional) Vertical(Omni) Antenna Power Gain Pattern. Vertical Field Pattern; Horizontal Field Pattern; Polarization Pattern. This article explores the performance of an unloaded vertical as a multi-band HF antenna. Much confusion exists about the radiation patterns of antennas. In particular, the Notice that this pattern has both the low-angle lobes and a broad vertical lobe.

  • VHF Marine Band Antennas by James W. Hebert.
  • A vertical antenna or loop antenna small compared to the wavelength is typically used, with the main design challenge being that of impedance matching.
  • This type of radiation pattern is both NONDIRECTIONAL (in a horizontal plane) and DIRECTIONAL (in a vertical plane).
  • In practice, the desired radiation pattern is achieved by mounting an array of antenna elements along the vertical length of a transmitter tower.
  • Some common antenna pattern plots and gain equations, alnog with half-power beamwidths and polarization types.
