Hey Radio Heads

Wed Feb 27, 2008 5:18 pm

No problem-just a question I don't have an answer for.
I have a 900Mhz PtP link here that shoots through 1/3 mile of solid trees.
S/N is typically 4-8 at a -86.
After the last two heavy snows when all the trees and every branch had 4-6" of snow on them the signal jumped to -80 to as high as -74 and stayed at those levels until the snow dropped off.
Anyone know the physics behind this?

My understanding is the trees scatter the signal, make for more self created noise. The snow limits the things in the way, less things, though larger, make for less reflections. Thats my theory right now.

I'm trying to figure out why my 900MHz works better during and after rain. I don't understand the difference there, unless the water somehow causes it to conduct rather than reflect.

Yes- That too.
Large water droplets hanging on branches can completely kill a 2.4Ghz transmission, but help a 900Mhz one.
