A factor to be taken into account when deciding whether to have shorted turns or an open coil is the possible corona discharge from an open end. This will also introduce losses. For a fixed station (portable is different as the antenna characteristics are difficult to predict) I would suggest a coil that is just too short, followed by a variometer. Of course this needs some experimentation, but during the experimental period it doesn't really matter whether the turns are shorted or open.
