The range of a wireless link is dependent upon the maximum allowable path loss. For outdoor links, you will get a strong signal as long as there is clear Line-of-Sight between the two antennas with sufficient clearance for the Fresnel zone. For Line-of-Sight, you should be able to visibly see the remote locations antenna from the main site. (Longer distances may require the use of binoculars). There should be no obstructions between the antennas themselves. This includes trees, buildings, hills, concrete, steel, power lines, or a drastic change in elevation, etc. As the distance extends beyond six miles, the curve of the earth (commonly called earth bulge) affects installation, requiring antennas to be placed at higher elevations. Use the 27dBi grid antennas for distance this far, or contact one of our technical consultants for a free path analysis. Please contact us to discuss purchasing a point to point connection, as there are variables dependent on transmitting a strong, reliable wireless signal.
