the sky at my parents place used to stop working everytime it rained and would only start working a few hours or days afterwards

think it needed a new dish and wiring, but dad didnt want to rip up all the laminate

think you need to get the engineer in, but dont let em fob you off, cos if its working the day they turn up, they wont do anything

hope you have more luck than my dad, his is still fooked
