My power antenna mast was broke, I purchased a new mast from this site, had it installed at the local car radio store, Mobile One in new orleans. Worked fine for a week, went back to M-1 to let them know it wasn't going all way down, they guy pulled it out, and attempted to reload it. He was unable to, they sold me a new antenna for $45.00, so I have this one for sale. Make offer.
