Polarization of Antennas can make a difference

Did you ever wonder why sometimes you'll see antennas mounted vertically and others mounted horizontally?



What You Will Learn in This Week's Podcast:

Do you struggle to understand why antenna designs differ?

In this episode, I explain antenna polarization and how the design impacts it.


  • Your antenna needs to be within the same polarity in order to receive what you’re trying to receive.
  • A vertically polarized antenna will pick up vertically polarized signals better than horizontal.
  • Radio waves are oscillating sine waves, and the frequency at which they oscillate is measured in a hertz.
  • Vertically polarized antennas are perpendicular to the earth’s horizon
  • Horizontally polarized antennas are parallel to the earth’s horizon.
  • Satellites are not in a fixed position, so we’ve needed to develop circular polarization to communicate with satellites when their polarization is constantly changing.
  • Vertically polarized antennas are the most common in general, and horizontally polarized antennas are common in the scanner radio hobby world.
  • A common example of vertical antennas is on cars.
  • Cell phones are the most common example of a need for cross-pole antennas.
  • Circular antennas are good for eliminating multi-path distortions.
  • A GPS and some drones use circular polarization.
