Itasca Sunova TV antenna Coax problem

Thanks Tommy. Yes I did that. I even clipped the coax back a few inches just in case there was water wicking up the wire. I also used dielectric grease to displace any water that may have gotten in. Since the antenna itself was so old I upgraded to a new antenna as well. Everything works fine if I bypass the coax. I suspect that flexing of the exposed part over the years has done it in. Coax doesn't last forever. In my younger days as a fire control (gunfire) technician on Coast Guard ships I replaced a lot of coax.
