    Hi All,

    Had my install yesterday morning.

    We had a small rainstorm come through yesterday afternoon and most of my channels were wiped out for a few minutes.

    I know during heavy rain this can and does happen.

    I jumped over to the satellite signal strength screen and 101 was still in the high 90's for signal strength, but 99 and 103 were in the 50's.

    Is that normal or should 99 and 103 have been higher? Is it possible that the dish wasn't installed properly?

    Just curious.

    Thanks!

    Rain/Snow fade will occur without precipitation when storm clouds are directly in your dish's line of sight. Wait till the storm passes and check your signal strength again. If they are still weak give DirecTV a call.

    Rain fade affects the HD signals from 99 and 103 much more than the ones from 101. This is because the frequency bands are different, the raindrops cause greater attenuation at the Ka band frequencies than at Ku band. It's quite normal for the SD signals to be OK and the HD signals to be severely affected, in fact many of us can revert to an SD channel when the HD channel is giving 771 searching for satellite messages.

    This is the reason why I keep my SD channels to "Show SDs" in the guide. Then I just make a favorites list of all my regular channels (minus the SDs) and when the rain fade comes, quickly switch to "All Channels" and more often than not, the SD channel is still there, rain fade and all. But yes, the signals on 99 and 103 are a lot fussier in poor weather.

    Exactly what you need to do. Your dish may not be properly aligned, but the only way to know is by checking when there are no weather issues. Your 99 and 103 signals should be in the high 80's or 90's (except on the "s" satellites, where you should have one or two high readings, but others can be low or zero).

    If any of the non "s" satellites (99a / 103ca/cb) are lower than high 80's, your dish needs adjusting.

    A poor dish alignment will increase rain fade chances. BTW, it's the rain drops that defect the signal.

    Rain fade happens more because of dispersion in the clouds than it does due to the local drops.

    It's actually just moisture period. I've had rain fade when a big tall cloud comes over the house and it never actually start raining at my house.

    It's the water droplets held inside the cloud.

    And a cloud over your house is likely to not be in the path of the sat. beam.....

    Since the tech had to pass IV and the install is so recent, we can assume that it is.

    Is it possible that since he had the install in the morning and rain in the afternoon, that the weather was already a bit iffy in the morning and the tech got an IV waiver?

    It very well could be. or IV was down (turned off) because of weather. This is the reason why customers should reschedule an install when on adverse weather.

    Actually the sky was clear blue when the install happened in the AM.

    Rain rolled in in the early evening.

    All the satellites are in the high 90's when the sky is clear...

    IV is by market. some markets are very big. so it does not necessarily needs to be raining on or around your house in order for IV to be turn off

    It's a test they do to make sure the signals are high before an installer leaves.

    IV is installation verification. Every DirecTv receiver we install has to pass IV in order to work. Sometimes IV is turned off on rainy days, some installers might take advantage.

    There are two ways to test your dish alignment a system test(,settings,info and test) will check your satellite signal using IV standards and give you an error code if there is a problem.

    You can also rerun satellite setup and if there is a problem you will get red x's.

    Update....

    So we've had several torrential rain events and I have had no other rain fade.

    Odd that it happened on installation day and never again.

    Thanks All
