Polarizations on a Grid Antenna

The antenna must be aimed so that when you look out from the center of the antenna it is pointing

toward the receiving antenna on the other building. The radio signal radiates from the end of the

antenna like a wide-beamed flashlight.

Vertical Polarity Horizontal Polarity

In order for the antennas to operate correctly, the polarities must match!

For most applications we have found that horizontally polarized antennas work best. This is because

most other signals that may cause interference are vertically polarized. If you use horizontal

polarization, you can reduce the interference caused by those other signals.
