Terrestrial transmitter data

The example RFI simulations focus on digital television (DTV) transmitters and specifically a single antenna located in Perth, AU. However, there are a significant number of DTV as well as other terrestrial transmitters operating in Western Australia. Information has been gathered on the current broadcasting transmitters in Western Australia from several sources including the Australian Communications and Media Authority (ACMA) license register, Oz Digital TV and TX Australia. The ACMA is extensive and, if desired, a full list of transmitters is available from the link above (note the full file size will be several GBs). A CSV copy of the simplified ACMA information for only the Western Australia DTV antennas is included in the data/transmitters directory (Filtered_DTV_list_plain.csv) which is usable with theses simulations. Other example CSV files are also present in the directory, containing only a handful of transmitters, which can be used for testing. Alternatively, filtering the larger csv file for specific areas or frequencies can provide larger sub-groups to simulate.

The main characteristics of the DTV transmitters have been taken primarily from a copy of the current license register from ACMA, which provides power output, direction of polarisation (H, horizontal or V, vertical) as well as antenna type (e.g. omnidirectional or directional). A number of the transmitter types have beam pattern information available alongside the license information, which contains antenna gains for a number of azimuthal directions. Where no further information is available, the transmitter is assumed to be represented by a fixed-link antenna as described in F.699-7. The map below shows the locations of the SKA-Low stations and the DTV transmitters in Western Australia that transmit in the 50 - 350 MHz range. The map below shows the locations of the SKA-Low stations and the relevant transmitters in Western Australia that transmit in the 50 - 350 MHz range. DTV and DR (digital radio) transmitters are shown by default. FM transmitters can also be shown by opening the map. The colour range displays groups of transmitters based on their emitting power.
