I am erecting a ½ wave dipole. I am curious as to what height off the ground will offer optimum performance? I have a 140ft long dipole for 70cm - 160 meters amateur radio and the optimal height was over 100 feet up in the air between two trees on opposite sides of my property. What would the optimal height be for an 11 meter ½ wave dipole? Thanks!

A dipole can be installed at any height, the higher the better for distant, I ran one (inverted V) about 12ft off the ground with good results. The ham antenna uses a balun to compensate for irregularities, never seen one go up to the 70 cm band. Are you going to use a balun ?
