½ λ Horizontal Di-Pole

½ λ Horizontal Di-Pole

Construction
  • 2 masts
  • 2 x ¼ λ antenna elements connected via a CJD
Use Static, HF skywave working
Range 0-3000Km dependent upon antenna height
Polarity Horizontal
Radiation Pattern Omnidirectional up to 300Km, broadside on after that
Propagation Skywave
Advantages An efficient skywave antenna that can be remoted from the set. Good receive antenna on skywave
Disadvantages Occupies a large area. Narrow bandwidth so requires changing for each frequency in use (antenna must be within 3% of required length for maximum efficiency
