Re: [AFMUG] High-voltage lines interference
I remember the original NCR WaveLAN 900MHz installation guide recommended not installing near power lines. I have successfully done links in 900, 2.4GHz and 5GHz through and near high power lines.

Re: [AFMUG] High-voltage lines interference
I have shot directly over a substation from a block away before, and have done numerous installs right beneath high voltage power lines. I actually have a site that is right below some lines up on the bench. I have never noticed any issues from power lines. What frequency are you running?

Re: [AFMUG] High-voltage lines interference
The situation you described of shooting through the powerlines is a similar scenario to where we have problems in the past. And building a taller structure to shoot over them because they were often the distance resolve the issue. In this case it will be shooting parallel to the powerlines because we are trying to connect to a tower that is 4 1/2 miles away at the electric substation. I am planning on going back out Monday weather permitting with a drone try to verify that I can see the tower at 90 feet. Hopefully with multiple options for frequencies we can find something that will connect.

Re: [AFMUG] High-voltage lines interference
I only remember going through lines like that once, and the signal was erratic. This was with FSK Canopy on a reflector. All I did was reposition the dish so the path was under the lines instead of through them, and that cleared it right up. I don't remember the exact range, it was across the road and across the parking lotmaybe 100-300 feet. I think it was more about having metal objects in the path rather than RF noise. I think the radio noise emitted by those lines would be a multiple of 60hz, and it should become less and less significant as you get more multiples away from 60hz. I welcome somebody smarter than me to correct that assumption. -Adam -- Original Message -- From: ch...@wbmfg.com To: af@afmug.com Sent: 11/16/2017 3:06:41 PM Subject: Re: [AFMUG] High-voltage lines interference I have never had issues, but I was always at least 200 feet away from the power lines.

Re: [AFMUG] High-voltage lines interference
Can you get them to pay for you to rent a JLG type lift that goes up to 100ft and do a site survey? Seems like with that big a life change they would be willing to shell out that to be sure.

Re: [AFMUG] High-voltage lines interference
What kind of High Voltage? Long distance 115-800KV lines or local 80KV lines? We have an AP ( not tall ) sitting 100 feet below HV lines on a hillside. It doesn't have any effect other than the lightning halo we enjoy...
