On my GTA when I purchased it it had a power antenna power would not cycle up and down and was extened to 3 sections. I have since replaced it with a use one. Now when the antenna goes up only two mast section are showing. Is this normal? I seemed to have lost recpection on 97.1 but other signals come in but are hazey. I also used my old antenna wire and notice it had some white compond (is this heat sink) were the wire mated to the antenna. Should more be added here?
