what antenna can I use with this?

I mean for example https://www.ebay.com/itm/163765405254

I haven't done this type of thing in years, I live in hades where we don't have any OTA antenna for TV or Radio, car radio does work though.

I know that will or should work for FM but I think if you want AM you need the loop antenna? not sure.
Looks like a circle.

Edit: just did a quick search and you will need a different antenna if you use AM, that will work for FM or you may find another type but
make sure it says FM.

I do have both types, the flat one like you attached the link and know that worked for FM in the past, the AM is different.

If this can help, these are the extracts from the User/Service manuals.




Service Manual mentions ATB7004 and ADH1017 but ATB7009 and ADH7004 are a substitutes.

You need to find models that have naked wires connection to fit in the Spring Clips FM/AM.
