 antenna mast problem
Hi, my old antenna mast would only go down 2/3 of the way and when i took it off i realized the bottom piece was rusted to the bottom of the antenna mast itself. after weeks of liquid wrench and anything else i could find around the house to make it come free, i ordered a new antenna. When it came i took the old one off and stuck the new one in. The motor took the antenna and to my dismay it again only went in 2/3 of the way. Theres is a small silver piece of metal that is larger than the rest of the shaft on the very bottom of the antenna mast and it will not go into the hole. I can no even screw it on. Please help. |
