Oh boy, here we go again. :S That so-called wall plate "booster" has
no ability to amplify the signal and is therefore
not a "booster". It simply switches the signal to the television between the cable feed and the antenna feed, and when switched to the antenna routes 12 vdc to the antenna head which is where any signal amplifier (if there is one) is located. An exception would be the
Winegard SensarPro I have which replaces a passive wall plate and does offer up to 10 db of signal gain or attenuation.
