Always problems the same as you mention, here (for myself)in Pensby/Thingwall area. It's OK on the BBC channels, but anything else is as you describe.
Having said that I do have water coming in through the arial. Comes out under the tele when the rain is really bad. Then I put the end of the arial into a mug and drain it. Fortunately the controls are on the opposite side on the tele.
