In Australia, we have 2 ways that TV reception is transmitted – in a horizontal pattern and in a vertical pattern. No, they don’t do that just to watch the travellers stand outside their vehicles getting frustrated turning their antennas up and down, this way and that (although, sometimes it seems like that). There are a couple of reasons for the way the TV reception is broadcast.
Let me explain. I am NOT going to use technical jargon so all you ‘techos’ out there, don’t call me to tell me I’m not completely correct; I am just going to explain the TV reception in simple, layman’s terms.
For the transmitters that need to cover a large area, the VHF frequency transmitted on the vertical plane travels longer distances with less loss of picture quality. So the transmitters at Orange, Canberra, Coonabarabran, Bundaberg, Shepparton and many more have vertical transmission as well as horizontal transmission.
The second reason that the vertical plane is used for TV transmission is to avoid interference with transmission from another close tower; for example, the transmitter for Noosa/Tewantin in Queensland sends its reception on the vertical so that it would not clash with the transmission from the Sunshine Coast transmitter.
And THAT’S why the Saturn Antenna has 2 aerials – one on the horizontal and one on the vertical. It is set up for ALL transmitters. Whether the reception is sent vertically or horizontally, with a Saturn Antenna YOU DON’T NEED TO KNOW – just put the antenna up, plug in your cable, press auto tune on your TV AND IT’S DONE!
