Evil Walrus

So I bought an atari 2600 online and got it in the mail today. Hopefully the system itself works. But right now I am having trouble connecting it. My tv has 3 vhf screws(not really screws idk what to call them), one says ANT input, another converter output, and the last AUX Input. It also has 2 UHF screws below that. I have a TV/game/computer switch but it does not have prongs like most, it is only a copper wire sticking out of it. I also have the power cable. So what do I do exactly? =p
