101 uses ku band, 99 and 103 use ka. ka is more susceptible to rain fade.
Signal Question
Hey guys, I have a question. Are different signals affected by rain/clouds more than others?
I had my dish re-aligned a few months ago and was consistently in the mid 90s across the board (on the ones that matter, mind you.)
I am experiencing a severe storm right now and lost signal. I'm bored so I decided I would check out my levels and here's what I've found:
On 101: right now, mid 60s to 70s
110: mid 70s
119: mid 70s
99 (c): 0s across the board
103 (ca): 0s across the board
103 (cb): 0s across the board
Just thought it was odd that everything was in the mid 90s before and a storm SEEMS to have caused me to lose signal more severely on different transponders.
Is this possible or do I have a bigger problem?
Thanks.

Yes, KA signals (99 and 103) attenuate much more from rain than KU (101,110,119).
