If the Sensar Pro is working properly then you should get the exact same results from the standard wall plate and the Sensar Pro pointed exactly the same when you have the Gain set to 10. 10 does not add or subtract any gain. If you have "some" signal with the standard wall plate but it gets worse when the Sensar Pro is installed you either have it wired wrong (unlikely) or you have a bad Sensar Pro and you should contact Winegard Tech Support for a replacement. I have had bad Sensar Pro's so I know that this is a possibility.
