No, it had nothing to do with the motor. I'm under the impression that the 'mast' is the telescoping piece? However, I suppose it could be the piece that rides up inside the telescoping piece? Anyone have an exploded diagram? This was done under warantee, so no charge. I'll keep getting it fixed until my warantee runs out, then I'll probably go with the S2K 'fix'. Integra antennae problems are very, very common. Suprised there hasn't been a recall.
