parts for winegard power antenna

Thanks for all your replies. I called their tech line and they are mailing me -parts. About a year ago, when the motorized part failed. DRV (who we ordered our trailer from) wanted 550 bucks for a new antenna. I declined and sent the motor portion to winegard for repair. They could not repair it and sent me the entire new antenna for 260 dollars. DRV didn't make enough building our trailer and wanted even more.
