I own a 76 Airstream Land Yatch by myself and am trying to figure out how to hook up my TV to the roof antenna. I have jack outlets on the inside walls that are round and have a vent looking piece protecting them. I am trying to find out where I can buy a jack that goes into this round outlet on one side and hooks up to the back of my TV on the other. I am definitely low tech here, just an old TV, no VCRs etc. Can anyone tell me what this part is called and where I can buy it. ( Speaking of antennas, I have found the crank on the roof for the antenna, but if i find that isnt working, there appears to be a great deal of info in the forum already) Thanks for not laughing (too hard) at me and for any help you can give me.
