What causes strength to fade in and out
 

Hello.

I am having trouble with my signal strength fading between 57 down to 25. It tends to drift between these ranges. It pickelates when it gets down low.

What causes this to change. Over a period of 10 seconds it could drop in half and then back up.

Could wind cause this?

Could be multipath. Or environmental conditions.

I have a similar problem with two weak signals at my location. One is VHF and the other UHF. Both are 2 edge signals and 55 to 85 miles distant.

Yes, as the wind moves the branches on the trees, the normal signal patterns are interrupted & can cause erratic signal strength swings.

I said this before, and I still believe that this is true: the Stacker antenna is not the best antenna for your situation. NYC should be a very easy catch from Norwalk. I believe that you may have an aiming issue, or possibly bad coax cable fittings, but my first suspect is that Stacker Antenna: it isn't really a fringe-area antenna, and no specs exist out there to confirm exactly what it DOES do.

If you are only seeing 57 on most stations from NYC, the antenna system is NOT doing it's job: you should be seeing signals in the high-80's to low 90's at your location.
