Antenna near Alice Springs?

G’day,

In 2015, I did a tour from Alice Springs to Uluru. We drove by some sort of antenna installment, I think it was near Alice Springs. If I remember correctly, at the time our guide said that it was some sort of space-related antenna. But I can’t seem to find any information on it. Can you please help me?I have attached the picture in question.

Thank You,
Jamie Fehr

We think this is probably an HF (shortwave) antenna used for long-distance aircraft communications, possibly operated by Airservices Australia. Can anyone identify it for sure? If so, leave a comment on this post, or email Jamie directly.
