It will reduce fading due to polarity shift as well as allow you to receive either H or V polarity equally well at the same time. Many years ago I ran a Wilson Shooting Star and had it set up to run V or H or both at the same time. In theory there is a 3 dB loss on transmission when running both polarities at the same time due to the power being split between the two antennas. In practice this is overcome by the reduction of losses due to to the receiving station using the “wrong” polarity.The other disadvantage is that you have to pay attention to the lengths of cable feeding each antenna as well as the feedpoint impedance of each antenna.
