Are there any problems with digital TV reception in Edgewater when it rains?

We have dreadful reception when it rains & we're on a high part of Edgewater. In the last few days we have totally lost all channels except 44 so no Olympics unless we watch it on the Channel 7 iPad app! We used to only have minor pixelation problem with channel 7 and occasionally SBS but resetting the TV hasn't worked and our aerial is still intact 😢

Not that I have experienced over the last 4-5 years, Edgewater as a Suburb is raised with views to the city and over Wanneroo. I would say it would have better than average reception over the general Perth area
