There exist also the Titanium product line of Ubiquiti which in theory isolates the radio and the electronics from the environment interferences. But I have never tested it.<br><br>The best man I ever met to ask about such topics is Ermanno Pietrosemoli, I'm sure he will be glad to help you. He has the current WiFi long shot record (something arround 380KM). This article is from 2007, a little old but can give you an idea [1].<br>

</div>Hi,<br>
<br>
In a noisy environment did someone try to put an horizontal wire fence<br>
below the dish to try to isolate it from ground level interference ?<br>
<br>
We operate a 5.5 GHz network in the city of Toulouse, France (700k<br>
people) and up to now we've had no issue with interference, noise levels<br>
reported by ubnt gear are pretty good so far (whatever they mean).<br>
<br>
Sincerely,<br>
<br>
Laurent<br>
