MA 2-1 MR

Marine VHF Antenna with Low Wind Load

DESCRIPTION

  • This marine VHF antenna is developed especially for sailboats where low weight and wind load for a masthead-mounted antenna is essential.
  • The tapered 1/2 λ stainless steel radiator together with glass fibre matching unit housing, chrome plated brass parts and stainless steel corner bracket make this antenna tough and ready to cope with the corrosive environment at the masthead.
  • The end-fed dipole principle makes the antenna independent of ground-plane, radials or other auxiliary arrangements.
  • The antenna whip should not be mounted parallel or near to other metal parts such as windex, supporting wires etc. Free mounting and as high as possible is preferable, otherwise the SWR and the radiation diagram will be influenced.
