5 Interpretation

(1) In this instrument, unless the contrary intention appears:

ARPANSA standard means:

(a) the Radiation Protection Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz (2021) published by the Australian Radiation Protection and Nuclear Safety Agency; or
(b) if a later document is published by the Australian Radiation Protection and Nuclear Safety Agency to replace that standard – the later document.

Note: The ARPANSA standard is available, free of charge, from the Australian Radiation Protection and Nuclear Safety Agency’s website: www.arpansa.gov.au.

dummy load: see subsection (2).

group of stations means two or more stations transmitting simultaneously on the same or multiple frequencies.

screened room means a room that prevents, or is designed to prevent, the entry or escape of radio emissions from that room.

shielded enclosure means a container or other thing that encloses a space, which prevents, or is designed to prevent, the entry or escape of radio emissions from that space.

Note 1: A number of other expressions used in this instrument are defined in the Act, including the following:

(a) equipment;
(b) frequency band;
(c) frequency band plan;
(d) operate;
(e) radiocommunication;
(f) radiocommunications receiver;
(g) radiocommunications transmitter;
(h) radio emission;
(i) transmitter.

Note 2: Other expressions used in this instrument may be defined in a determination made under subsection 64(1) of the Australian Communications and Media Authority Act 2005, including:

(a) Act;
(b) EIRP;
(c) FM;
(d) harmful interference;
(e) land station;
(f) mobile station;
(g) necessary bandwidth;
(h) pY;
(i) station;
(j) ultra wideband station.

(2) A dummy load is a thing that: (a) is used, or designed to be used, as a substitute for another thing that is capable of radiating radio signals that are fed to it from a transmitter (the original thing); and (b) has impedance characteristics that are the same as the impedance characteristics of the original thing; and (c) is both: (i) incapable of radio emission; and (ii) designed to prevent radio emission occurring.

Note: Example: A circuit that is connected to the antenna feed point of a radiocommunications transmitter to simulate the effects of a real antenna without allowing radio emissions caused by operation of the radiocommunications transmitter to travel further than the dummy antenna.
