SLOPING WIRE ANTENNA

The Corps Colours

Construction
  • 1 x 12m mast or (suitable support)
  • Single ¼ λ antenna element as vertical as possible
UseTactical, HF net working. Also useful for short range mixed net working where a mixture of surface wave and skywave is required
Range0-100Km
PolarityVertical
Radiation PatternOmnidirectional with slight gain in the direction of the set
PropagationPredominately surface wave. Skywave radiation increases as slope on the wire decreases
AdvantagesQuickly erected. More efficient than a vertical radiator of the same height because a full ¼ λ wavelength can be achieved
DisadvantagesNot suitable for frequencies below 4Mhz as antenna becomes more horizontally polarised than vertical
RemarksA compromise antenna that radiates both surface wave and skywave and therefore inherently inefficient for either
