: I know that an inverted V is for the most part omni directional, but what about an inverted v that is only somewhat inverted? Would that not give you a pattern more shaped like an egg? The directivity of a half wave dipole over real ground varies with height, and elevation angle. At the zenith it is omni directional, and at lower elevations it has some directivity, but nothing like a dipole in free space. Inclining the legs as in an inverted V dilutes the nulls further and so reduces directivity, less so for large included angle. So, the combination of an inverted V and mounting low to real ground reduces directivity. If you raise your dipole centre height, and decrease the included angle, I expect that one will offset the other's effect on the pattern to some extent. Owen |
