4 Additional device boundary of a radiocommunications transmitter

(1) The additional device boundary of a single radiocommunications transmitter is established as follows: Step 1: Calculate the additional device boundary criterion at each m×500 metre increment along each of the n-degree radials, where: m is each of the integers from 1 through 400; and n is each of the integer degrees from 0 (true north) through 359. Step 2: For each radial, find the latitude and longitude of the first point on the radial, moving away from the location of the radiocommunications transmitter (that is, with the lowest value of m) where either: (a) the additional device boundary criterion, HRP – Lb – CR, is less than or equal to 0; or (b) m is equal to 400. This point is the end point of the radial. Step 3: The end point of each radial is the additional device boundary of the radiocommunications transmitter connected to that radial.

Note: HRP – Lb – CR (the additional device boundary criterion) is calculated under item 5.

(2) For a group of radiocommunications transmitters the additional device boundary is calculated as if for a single radiocommunications transmitter.
