The longer antenna has more lobes and improves the DX capabilities of theantenna. The horizontal, fields are very similar with the longer antenna having an additional central lobe.HorizontalFar Field3/2 λ Asymmetric AntennaTotal V=H FieldsOver head viewVerticalFar Field3/2 λ Asymmetric Antenna Total V=HFieldsEnd viewDrawn by G8ODE May 09 iss a
