Everything is in very good condition. Unfortunately I was not able to thoroughly test it as I don't have an older TV with the right hookups. The instructions specify the two-pronged UHF-VHF connectors. I tried using an adapter between the RF plug and the coaxial cable input on my TV but was not able to get it to work. It may require a TV set with the older connector. Sold as-is, no guarantees. Free insured shipping anywhere within the U.S. International shipping will vary by destination; please ask if interested.
