IFrogz case is degrading my signal

[X-rated]

I purchased the singal piece ifrogz case and with it on I constantly have a single bar 3G but when I remove it it goes back up to full bars just like when I touch the left side. Is anyone else having that problem. I sure hope when my bumper arrives it doesn't have the same affect.

I have the ifrogz lean and it's fine
