I'm assuming that the wall plate and the pilot light indicates I have a amp in the antenna head, and assuming I do, What's next? Is the amp replaceable of do I need a whole new head?
You most likely have an amplified antenna but it's possible that it could be unamplified. I have had both an amplified and unamplified Sensar III antenna head. The unamplified antenna had a wall plate with amplifier and it also had a pilot light.
Here's a site with some excellent tips from Chris Bryant:
