I have some questions for the group. How would one decide whether the ends should be left open, versus connected together to make a loop? (I never could figure out how to model antennas using EZNEC. It should be called HARDNEC.) Does it make a lot of difference? Using a tuner near the feedpoint, which way would give a better match on more bands (160-10m), open or closed ends? Which way would yield stronger signals in the most directions? Is it the case that, below a certain total wire length, the ends should be left open, but above that length, they should be connected together? I guess the only way an indoor antenna of typical length would match on 160m, even with a tuner, would be if the ends were connected together and the whole thing was treated as a very bent end-fed wire working against ground and a counterpoise.
