I tried searching for this on Google but without any luck. On my multi-switch, the terrestrial input has the same thread? (I hope that's the right word in English) as a normal Sat cable, however the inside is different and there's a small screw that goes through.

I'm bad at explaining but I'm sure some people know what I mean. What I wonder is what cable to use here? The "normal" terrestrial coaxial or the sat one (with F-stecker) or another cable? Also, what do I do with the screw?

Ps. yes I'm new to this and with the lack of Google results I guess all this I ask is common sense >_<

Normal 75 ohm tv coax should be fine, the little screw is for the inner solid cable. The outer braid is connected normally to a clamp. I am assuming that this cable is connected to a tv aerial.

As you could read by my post I don't know the names of the cables but thanks for teaching me that :P However I don't understand why they would make that one different when all the inputs and outputs are the same. I will attach a small aerial with this, yes.

Thanks for the help again. I'll test it out once I get back to my house.
