snow and signal

hi,

I have a link on 7 km with rb112, CM9 and grid 27db.
usualy, signal is -59db, but tonight I notice that signal is -77 db. Is it possible that snow is cousing that?

I would allso like to know wich is minimum signal for qualitet link?

Yes, link is on 5,8 GHz.

Thanks…

Snow will have that effect.

What are you showing for noise levels?

noise level is -101db
signal to noise 27 db

Experience says I worry about anything that is worse than -75 reality says I have reliable links as bad as -84 still pushing 5-7 megs of throughput…

Guess it depends on how much snow.. last winter i had no problems at all with snow, but we’re talking of not much (about 70 cm and 5/6 times)
We do not use any grid, just panels, and this may help -.
