Point-to-Point LinksPoint-to-Point Links

Parabolic-type antennas are always the best 7 for point to point links: Also known as “dish” or “grid: antennas.

If you are familiar with Ubiquiti equipment: The NanoBridge series is the best equipment for point-to-point links: One NanoBridge on each end of the link.  For very long-distance links (over 7 miles):  Use a Ubiquiti RocketM5 with a RocketDish on each side of the link:  Use the 30dBi RocketDish (2-FT diameter) for less than 20 miles.  For more than 20 miles, use the RocketDish 34dBi, which is 3FT in diameter.

Long-range wireless links:

If you are not an expert, and you are experimenting with trying to make a very long-distance link:  Try this:

  • Use signal booster with a high-gain antenna on one end, and test the link.
  • If it’s not enough signal-strength:  Put a high-gain grid antenna (such as the A24 Grid Antenna above-left) on both ends.

To reach a signal higher or lower than your elevation: Use smaller dBi omni dipole antenna: 2dBi, or 5dBi (not 9dBi or 12dBi). Of the omni-directional portable antennas, 7dBi has the optimal balance between horizontal and vertical range.  Read details
