You can't add an amp to the Winegard antenna which is already amplified (at the head where it does the most good). Sometimes, where you are located vs. where the broadcast is located requires MORE and/or higher antenna. If you are going to be there for an extended period you can look at some of the higher gain antennas that you can mount on a taller pole. If you plan to move on soon you can try adding the Winegard Sensar Pro https://winegard.com/cart.php?suggest=51d2377d-438f-4109-9d1d-d5f6e521feb7 which does have some additional boost but most importantly a signal meter to ensure the antenna is pointed in the right direction.
