I received these SKYREAT Copper Parabolic Antenna Range Booster today but noticed that the surface is not smooth. There are a couple of indentations and a convex bubble on one of them. I tried to highlight it in the photo with a red circle around it but its hard to get my iPhone to focus on it due to the reflection. I guess the question I have is this ok or will it be a problem to reflect the signal to increase my range. It's been raining here for 4 days and will continue over the next 2 so I can't try them out. Should I send them back or does it not matter. Thanks for the input.
