This Interim Standard covers the design and manufacture of antenna for reception of digital terrestrial TV transmitted in the high VHF and UHF bands. It also covers measurement procedures that may be used to determine the performance of the antenna. This part is aimed specifically at manufacturers to create products suitable to the Australian environment.

This Interim Standard specifies the minimum electrical performance, aspects of mechanical design and methods of measurement of antennas for reception of terrestrial digital television broadcasts.Requirements for analogue television transmissions are not considered in this Interim Standard. Analogue television transmissions in Australia are in the process of being switched off, with this process to be completed by 2013.NOTE: This Interim Standard only considers receiving antennas suitable for Australian digital terrestrial television services that operate in VHF Band III, and UHF Bands IV and V.Band I or Band II reception capabilities are not required for Australian digital television, and Band I low VHF reception capability for analogue channels 0 to 2 should not be included, because this may be detrimental to the required performance for digital television channels.To provide reliable uniformity to antenna performance specifications and as an indication of suitability of an antenna for reception of DVB-T signals, information on methods of measurement is given, including aspects of COFDM measurement such as bit error ratio (BER) and modulation error ratio (MER).NOTE: Appendix A gives details of infield measurements and some practical examples of expected results for a range of signal conditions and different antenna types.A possible future Part 2 of this Interim Standard will cover mechanical aspects of the installation of outdoor television receiving antennas. For details of how an antenna output should be distributed to multiple outlets such as required in multi-unit-dwellings, refer to AS/NZS 1367. NOTE: Additional ancillary requirements may include (integral) filters for rejection of interference from devices using adjacent spectrum such as LTE mobile telephony and ‘white space’ devices (for wireless computer connections).
