Replace it with the SENSAR PRO module.. Please do it that way
The Sensar Pro should work on a 2002.. Some of the earliest Winegard antennas were not amplified,, but by 2002 I do not think those were being installed.
Why do you need to replace it?
If you have a short coax jumper try this.. Remove the wall plate but do not disconnect... Attach a short coax jumper to the ANT connection (Looking at the back with the 12 volt outlet at the top this is the left one) Turn on Switch and CAREFULLY measure voltage at other end of jumper.. 12 volts.. it's a power supply. ZERO.. Well, read the model number off it and then go to Winegard
But the Sensar Pro replaces the power supply ones And greatly improves operation.
