uBlox M8T & antenna behind two panes of glass skyview is a 170 degree sweep centred 30 degrees east of south I regularly see attenuation with overcast clouds, but only with some overcast clouds. It's not consistent enough to be able to say which types. The attenuation can be as much as 10 dBc, sometimes more. If all the sats suddenly show as way down, that's a sign to go outside and look as it's usually tornado-friendly conditions. And if the wind hasn't picked up yet, it soon will. Often, the attenuation from overcast clouds is relieved once the rain starts. But rain can also make it worse. Droplet size or rainfall density? No consistency with snow either, except for the really thick snowfall, which is usually, but not always, a wet snow. Few trees in my view to show differences when they're wet vs. dry. If the rain is being blown against the sides of the brick buildings low to the horizon across from me, once they're soaked, I get multi-path: - from the sats on the other side of my building, which are a little off from 180 degrees opposite my view, from a range roughly 30 degrees wide and between five to 35 degrees elevation; and, - also from a few weak sats signals from just around the corners of my building and just beyond the roof edge, usually within ten degrees beyond the edges of my building. The ground is almost always wet before the sides of those buildings are soaked, but the hit of multi-path comes with those building sides getting soaked. Long & tall hedge across in front of most of those buildings. I've always assumed it was reflecting off the buildings. Michael
