Here are some photos from a PTP450i 900Mhz link going about 1.75 miles. We couldn't see either end of the link. Big shout out to Adam who helped with POC. With the beautiful trees and crane in the LOS the link came up and passed around 4Mbps in a 5mz channel. Just remember even though you can't see the Cambium radio, they can hear each other just fine.
