Seeing as you already have a vertical, try the dipole as horizontal. On DX, signal polarity tends to twist around. A signal may be launched horizontally yet when it comes back down on the other end, it may be more vertical and you'll see a bigger signal on your vertical. Or it may come back down stronger in the horizontal plane. And if you talk with the station for many minutes, it can switch around back and forth while you're talking. So it is a good thing to have both capabilities and you can switch back forth between the two (with a two-position coax switch) and simply see which antenna is hearing better at any given moment.

Dipoles will not require a balun unless you're experiencing RF feedback or spurious radiation from your feedline with a particular installation. In this event, add a 1:1 balun at the feedpoint. This changes nothing impedance wise, just isolates the coax so it cannot radiate any signal.

good luck
