I have a situation where I need to mount a few relay units on the electric company poles (with permission of course) with 2.4 GHz flat panel antennas with minimal space on the poles.
After much research, I have not been able to locate any information as to the minimum distance that a 2.4 or even a 5.8 GHz antenna can be mounted near the electrical transformers without any interference.
If anyone has this information, please reply to this topic and/or give a internet link to the documentation. This would help a lot in our decision as to attempt what we want to do out in a remote area for customer coverage.
Interference is not your issue. The required separation from your equipment to anything >4.4kv is 54" in the US. This is vertical separation by the way. You could also face a minimum of 12" separation from any other utility such as a cable or telco.
We have been forced to abandon some poles, as the required minimums would have our equipment less than 6’ off the ground.
Thanks for the info…the information we received from the local electric company said 40" below the weatherhead (or entrance). But like you said, we have some “short” poles and meeting the minimum clearances with their equipment seem to be a problem.
I thought as far as the performance issue goes that their would be an EMI issue from the transformers themselves.
