What is a directiondirectional antenna?

What is the difference between a high-gain antenna and a directional antenna?

  • Directional antennas provide increased performance over dipole antennas —or omnidirectional antennas in general—when greater concentration of radiation in a certain direction is desired. A high-gain antenna ( HGA) is a directional antenna with a focused, narrow radiowave beam width, permitting more precise targeting of the radio signals.

What is the radiation pattern of a dipole antenna?

  • The dipole radiation pattern is 360 degrees in the horizontal plane and approximately 75 degrees in the vertical plane (this assumes the dipole antenna is standing vertically) and resembles a donut in shape. Because the beam is slightly concentrated, dipole antennas have a gain over isotropic antennas of 2.14 dB in the horizontal plane.

How do I know which direction my antenna is aimed?

  • By simply entering your address in the website, you’ll receive a local signal report that allows you to see the channels you’ll likely pick up, and from which direction they’re being broadcast. This way, you have all the information needed to determine the direction to aim the antenna.
