21  Maximum field strength within the licence area
AM radio band
 (1) A transmitter operated to transmit an AM radio service must not be located at a site if operation from that site would result in more than 1 per cent of the total population of the transmitter's coverage area within the licence area receiving that AM radio service at field strengths greater than 120 dBµV/m (1 V/m).
Note: Subguideline (1) deals with potential interference and/or degradation in receiver performance due to excessive signal levels at the input terminals of the AM radio receiver.
FM radio band, digital radio, television and datacasting services
 (2) A transmitter operated to transmit a service other than an AM radio service must not be located at a site if operation from that site would result in more than 1 per cent of the total population of the transmitter's coverage area within the licence area receiving that service at field strengths greater than 110 dBµV/m (316 mV/m).
 (3) A transmitter operated to transmit a service other than an AM radio service must not be located at a site if operation from that site would result in the lesser of:
(a) 0.1 per cent of the population of; or
(b) 100 persons within;
the transmitter's coverage area within the licence area receiving that service at field strengths greater than 120 dBµV/m (1 V/m).
Note: Subguidelines (2) and (3) deal with potential interference and/or degradation in receiver performance due to excessive signal levels at the input terminals of the broadcasting or datacasting receiver.
 (4) In this guideline:
Census means a census taken under the Census and Statistics Act 1905.
coverage area, for a transmitter, means the area in which the median field strength is equal to, or greater than, the planned minimum field strength.
population, for an area, means:
 (a) in relation to a transmitter authorised to operate under a transmitter licence issued before the commencement of these guidelines, other than a transmitter mentioned in paragraph (b) – the population specified for the area at the most recent Census taken before the transmitter was first authorised to operate;
 (b) in relation to a transmitter authorised to operate under a transmitter licence issued before the commencement of these guidelines, if a nominal transmission parameter specified in the LAP or DRCP that relates to the transmitter licence was varied before the commencement of these guidelines – the population specified for the area at the most recent Census taken before the most recent variation of a nominal transmission parameter before the commencement of these guidelines;
 (c) in any other case – the population specified for the area at the 2011 Census.
