    Free internet antenna?  Nothing is free, someone is paying for it. Are you looking to pick up an existing free wi-fi hot spot? If this is the case you will still need an ID and password to use it and most of these change frequently.

    What is an "internet antenna" in your mind?

    Three types of antennae would be generally useful for "Internet" access -- cell, Wi-Fi and satellite. We can probably eliminate 'satellite' immediately if "free" is expected, though you can find junk equipment that someone with experience can modify. But simply having an antenna won't be much help -- you need to process the signals and send responses back.

    And that's also part of the problem with cell and Wi-Fi, too, processing signals and sending responses.

    For "cell", you would need a device that does processing similar to what a cell phone does. A most important part of the processing is establishing an authenticated connection. It's not clear how any of it would be done for 'free'. Taking the antenna out of an old cell phone seems easiest and possibly cheapest.

    But it doesn't get you "Internet" except as much as the cell service provider provides through their cell network (for authenticated users).

    Wi-Fi might be easiest and cheapest in a similar way. Find an old wireless adapter that someone's throwing away and use its antenna. Then you only need to build the rest of the adapter to use it.

    Now, that doesn't get you "Internet" either. You'd only catch signals from whatever Wi-Fi provider is in range. (Range could be a big problem. It won't be as good as range for a cell tower.) If it's an open connection AND the provider provides Internet access, you might get useful signals.

    By itself, an "antenna" simply isn't a significant part of all that goes into Internet access.
