Dave, Open it at the point 180 degrees (midway around) from the feedpoint. If your existing loop is a full wavelength on 80 meters, opening it will turn the loop into a folded back 1/2 wave dipole on 160 meters - not as good as straight out, but it should work since you are feeding the line with a tuner anyway. In fact, you may be able to make it automatic by using a trap tuned to 160 meters - that will electrically open the loop on 160 and only add some inductnce on the other bands.
