I just got a box for mmds digital tv. but it's missing the connector that screws onto the aerial and connects the aerial to the box. I have been in touch with the supplier and although he says it was there mistake for not putting one in, has asked me if i can buy one here to spped things up, as it would take at least a week to post one out. Problem is I don't know what to ask for in the electrical shop. So anyone have a clue what its called. I have tried several times to contact the supplier again but they are not answering emails
