Long term rain outage

[w3mr]

Has anyone experienced a long term outage after rain? We have a system that experiences outages for a day after the rain stops and the skies are clear. I have changed the LNA and the cables and still experience low signal levels during clear weather. Can the dish itself become saturated and retain water? It's an old dish and the RCA lettering has faded out. My next approach is to replace the dish itself.
Any ideas?

I suspect time for a new dish. I live in Florida and my rain fade during the height of a downpour lasts maybe 5 minutes.

You replaced the cables and LNB but did you seal the cable connectors or use weatherproof fittings? I can't imagine the dish itself could get saturated. My old first-generation dual-LNB RCA dish, circa-1997, was metal painted a dull gray.

Is your dish aligned correctly? Low signal levels during clear weather is an indcation that it isn't sighted in optimally.

Also, check your connectors. Make sure they are not loose and preferably sealed. You can use good quality electrical tape to do this. Pull it tight.

Sounds like soaked connectors/cables and once they dry, which takes time, everything comes back. Like cawgijoe said, seal things up and a low signal can and will aggravate the situation. I know what hard rain is like and I have found the best bet is to have NO connections/ splices or breaks in the cables exposed to any weather.

I used to have long term rain fade. Turns out the dish was grounded to my aluminum gutters. :eek2: (really bad installers)

Once properly grounded the signal would return quickly during the few times we had really heavy rain. :)

Because your system is returning to "normal" after 24 hours, it really sounds like you have moisture problems somewhere.

Any ideas?From your terminology are you using old "C" band wiring to bring in the satellite signal? The dish unless it is physically damaged won't need replacement, metal dosen't get water logged. Old cables can become water logged and need to be replaced. Fittings exposed to weather for years will fail and need to be replaced. Have tree leaves grownout over the dish? when they are wet they can hang lower and block signal until they dry off.:)

Some of the early 3 slot dishes were fiberglass impregnated with metal filings to make them reflective. (I had one of these for awhile.)

These fiberglass dishes might get UV damaged and absorb water.

Still, my money is on the cables, or more specifically, the connectors on those cables. They're not water tight and water is getting in.

Never. I get bad reception during rain (even semi-heavy) and I just turn to my DVR.

When the rain stops, I get service back

I had issues with a new dish - seems one of the LNB's was not sealed correctly and water actually got in under the plastic cap. When it rained it would go out for extended time, until it finally crapped out all together. Maybe your issue?
