NOTE

  • This subclass covers:
    • in addition to the primary active radiating elements,
      • secondary devices for absorbing or for modifying the direction or polarisation of waves radiated from aerials, and
      • combinations with auxiliary devices such as earthing switches, lead-in devices, and lightning protectors;
    • both transmitting and receiving aerials
  • This subclass does not cover devices of the waveguide type, such as resonators or lines, not designed as radiating elements, which are covered by subclass H01P.
  • In this subclass, the following expression is used with the meaning indicated:
    • "active radiating element" covers corresponding parts of a receiving aerial.
