I just thought of something you may have seen before. Right up the street at the power substation is this huge telephone pole with a four element folded dipole vertical colinear aray on top. HUH? OK, that's four vertical folded dipoles each mounted 1/2 wave above the other evenly spaced around the mast for 360 degree coverage. It gives about 5 or 6dB gain over a single dipole and the impedance is matched as described above.
