Definitions

  • the cover 20 is placed over the opening and suitably fastened, thereby completing the construction of the antenna.
  • the finished omnidirectional receiving antenna 10 is now completely self-enclosed and it is impervious to metallically corrosive elements such as salt water spray, rain, wind and other corrosive elements.
  • metallically corrosive elements such as salt water spray, rain, wind and other corrosive elements.
  • the antenna is both horizontally and vertically polarized and is, therefore, not adversely affected by the rolling and tossing of a ship or boat on the high seas.
  • the antenna 10 should be mounted on a plane as near to vertical as possible, although minor deviations from this orientation will not deter the antennas operation.
