Hello,
we have some antennas installed on top of a tower close enough to other 5Ghz antennas, Radio and TV antennas.
Our antennas are some dishs and two sectorials.
We installed the RouterBOARDs inside aluminum boxes and connected them to the antennas and RF cables with pigtails.
All devices are grounded.
The connection between the RouterBOARD and the power supply is via FTP 5E cables and the power supply is located at the base of the tower. The cable length is about 20 mt.
On the tower, inside the ALUBOX there are one RB912, two RB433 and other one RB911, the mystery is on one RB433. After two days of normal use it can not be reached because its ethernet does not seem to work.
We thought that it was bad so we have replaced it with a new RB433, but after two days the problem is always the same.
At this point we marched the FTP cable cat. 5E and replaced with a new one and we have replaced the passive POE supply also.
After two days it's the same....
Is to be noted that the RB433 is turned on and running if we associate with an SXT from the base of the tower everything works except the impossible traffic data on Ethernet and the problem is not resolved by a reboot of the RB.
It 'possible that a given radio interference from other antennas placed on the tower is able to isolate the ethernet port of the RB.
But if that may be the problem because it only happens in this RB, we must remember that we have replaced it with a new one then exclude that defective, and not the others RB which are mounted a few inches away.
Thanks Cetalfio
