The so-called end feed is an old myth that has been around forever. My
very first antenna was just that, and I always wondered what that second
feedline wire would do when it just abruptly ended, unterminated, at the antenna
wire.

If you are talking about the "end-fed zepp" the unterminated feeder, sometimes called the "dead" feeder somewhat balances out the "live" feeder that connects to the end of the antenna. While the balance is not perfect and cancellation is not complete, the feedline radiation is significantly less than with a simple one-wire vertical feeder ( which would qualify the antenna as an "inverted-L").
