PART 1—PRELIMINARY
Citation
1. This Determination may be cited as Radiocommunications Licence Conditions (MDS Licence) Determination No. 1 of 1998.
[Note: This Determination commences on gazettal: see Acts Interpretation Act 1901, ss. 46A and 48.]
Scope
2. (1) This Determination sets out conditions to which a MDS licence is subject in the following manner:
(a) every MDS licence is subject to the conditions in Part 2;
(b) every MDS licence issued for a MDS area is also subject to the conditions in Part 3.
(2) However, if a condition in this Determination is inconsistent with a condition specified in the licence, the condition specified in the licence applies.
Interpretation
3. In this Determination:
“licence” means a MDS licence;
“licensee” means:
(a) the holder of a licence; or
(b) a person authorised by the holder of a licence to operate a station under the licence;
“MDS area” means an area mentioned in:
(a) an item in Schedule 1 to the Radiocommunications (Allocation of Multipoint Distribution Station Licences) Determination No. 1 of 1994; or
(b) section 1.4 of the Radiocommunications (Allocation of Multipoint Distribution Station Licences) Determination No. 1 of 1997;
“station” means a MDS station.
[Note: For the definitions of other expressions used in this Determination, see the Radiocommunications Act 1992, the Radiocommunications (Definitions) Determination No. 2 of 1993 and the Radiocommunications Regulations.]
PART 2—CONDITIONS FOR EVERY MDS LICENCE
Spurious emission of the station
4. The level of spurious emission, including the station’s intermodulation products, from a station must be at least 60 dB less than the station’s maximum EIRP.
Transmission power from the antenna
5. The transmission power of a station must not exceed:
(a) 100 watts at an angle of elevation of 5 decreasing linearly to 31.6 watts at an angle of elevation of 10; and
(b) 31.6 watts at an angle of elevation between 10 and 15; and
(c) 31.6 watts at an angle of elevation of 15 decreasing linearly to 10 watts at an angle of elevation of 20; and
(d) 10 watts at an angle of elevation between 20 and 90.
Transmissions using a PAL-B emission format with 1 vision carrier and 1 sound carrier
6. The transmission power of a station using a PAL-B emission format with
1 vision carrier and 1 sound carrier must not exceed the levels shown for the frequencies in Diagram 1.

USING 1 VISION CARRIER AND 1 SOUND CARRIER
[Note: This condition must be read with the technical conditions specified in the licence.]
Transmissions using a PAL-B emission format with 1 vision carrier and 2 sound carriers
7. The transmission power of a station using a PAL-B emission format with
1 vision carrier and 2 sound carriers must not exceed the levels shown for the frequencies shown in Diagram 2.
DIAGRAM 2—EMISSION LIMITS FOR A TRANSMISSION
USING 1 VISION CARRIER AND 2 SOUND CARRIERS
[Note: This condition must be read with the technical conditions specified in the licence.]
Tolerance for transmission of vision signals
8. A station transmitting a vision signal must be operated within +/- 0.0005% of the carrier frequency specified in the licence for the vision signal.
Tolerance for transmission of sound signals
9. A station transmitting a sound signal must be operated within +/- 500 Hz of the carrier frequency specified in the licence for the sound signal.
PART 3—CONDITIONS FOR MDS LICENCE ISSUED FOR A MDS AREA
Notice to the ACA about antenna characteristics
10. (1) Before operating a station, the licensee must give the ACA written notice about the following characteristics of the station’s antenna:
(a) the type;
(b) the number of elements;
(c) the height above ground level;
(d) the front to back ratio;
(e) the azimuth.
(2) The licensee must give the ACA written notice of any change to a characteristic mentioned in subsection (1) not later than 14 days after the change occurs.
