I've had my primestar dish for about a year now with no problems until now. I dont have the small plastic cap that goes on the LNB and never did have it, it's been thru thunder storms wind etc. In the last few days I have lost my quality but the sig stayed pretty much the same so I went out and noticed water in the front of the LNB, the bronze colored part, so I dried it out with a towel and bang works fine. I dont know why it's happened now but it did what can I put over the LNB to stop this, syran wrap maybe? Its the dual H and V type LNB one output
