D.E. Bishop,
I read your original post and I can't tell if you are asking a question and if so, what it is.
So here is an explanation of the 2 units (which are not interchangeable). The really old Winegard antenna(s) did not have built in amps so you plugged the antenna into a booster which provided less effective amplification. Once the amp moved to the head itself you plugged the antenna into a power supply and allowed the antenna to send an amplified signal down the line.
If you want to add a booster to your existing Winegard antenna you can install a Sensar Pro or buy a signal amplifier from somewhere like Radio Shack which would be installed downstream from the Winegard power supply (not between the power supply and the antenna).
