Paragraph 3

In paragraphs 1 and 2 above –

• “distance” means the distance from the relevant station or relevant apparatus; and

• “measured” means ascertained by making measurements of all components of the emission from such number of directions in –

  1. (a)

     in a horizontal plane; or

  2. (b)

     where the configuration of the site is such that it is not reasonably practicable to make measurements in an exactly horizontal plane, in a plane which is as near to horizontal as reasonably practicable, including at least four –

     1. (i)

        orthogonal directions; or

     2. (ii)

        where the configuration of the site is such that it is not reasonably practicable to make measurements from exactly orthogonal directions, directions which are as near to orthogonal as reasonably practicable,

     as is reasonably necessary to determine the maximum field strength of the emission at the distance specified, and the highest value obtained shall be taken to be the maximum field strength.
