Re: how to scan for AP signal with spectrum analyzer

Well here is a pix of a peak hold run over about 10 min from the front seat of my car about 5 miles out into nowhere TOTALLY SURROUNDED BY 500ft and higher mountain peaks in a valley. From this location 360deg all you can see are the sides of mountains. there is not a building in site. These signals are a practically a constant -40. As I was driving around I found only a few spots over a 15 mile area where they went away for a few hundred feet as I was driving. There is a military base about 30 miles away, but it's behind a 9,000 ft peak between us and there are no towers on the peak. These are awful strong and consistent power levels. This scan shows the spectrum from 4ghz to 6ghz. Do others of you see this kind of use?

If I am trying to do a 5.8ghz backhaul does it stand a chance? I don't see ANY frequency use on the MT use scan. Nothing shows up at all. I just get this crazy stuff with the SA.

Check out the -25 peak. I mean I'm sitting miles away from the nearest building in a hole.

I am going to guess here and say that maybe what You are seeing is harmonics from another transmitter?. Maybe it is an issue with radar, as the power levels they use could be very high?.
