I have an earlier Winegard windup uhf/vhf tv antenna, it looks like a "sensar III" but I think its an earlier one around 1994 onward. I need a schematic to repair it, the reception of vhf is not good and this is amplified through a separate path to the uhf and I am trying to work out what the SMD transistor and what I think is a diode are that are in the path. Any information would be welcome. Please email me snipped-for-privacy@clear.net.nz
