Aerial cable confusion

Could somebody do me a favour? Could you possibly check the aerial cable that goes from the wall socket to the television, and tell me whether the ends are male/female/both? I bought an double-shielded male->female aerial cable to try to fix some signal interruptions I’ve been getting with the new Freeview box, but I apparently need a male connector at both ends. The only adapter I have converts male -> female, so is no use at all. I don’t know whether the problem is that I bought a weird cable by mistake, the wall socket here is of the wrong gender, or something else, but I’m terribly confused…

Update: I’m told that normal cables are male->male, so it looks like it was just me buying the wrong type. Bit mean of it to say ‘aerial cable’ on the packet, mind.
