We have an ~2mile point to point with good line of sight. We have great signal strength (-50db) and connectivity. The link itself is strong and stable. One point of the connection is on a 150 foot tower that is also used by the local Sheriff departments repeater for their car radio units. The Sheriff is experiencing some interference from our link.
We are in the 5ghz range, they are between 155-159mhz, so I don't think we are walking on their band. At one point we were sharing a power source but that has been changed.
The only thing left I can think of is that the tower climber used unshielded cable for the run up the tower. That will be changed very soon once the cable arrives and I can reschedule the tower climber.
What else have I not thought of? The connection it self is using RB532 boards with SR5 radios in 19dbi Rootennas.
