The image you just posted answers your question, yes.
It was the Adelaide Hills translator IIRC.

Probably introduced around the same time as the one used by SAS-10.

Gosh this was bad, notice how the city skyline doesn’t change regardless of the angle.

The style of promos obviously has changed from straight movie images with basic graphics which developed over the decades. Adelaide still producing basic promos with little additions other than voiceover and single title/date/time/network graphic but using the network supplied ident from Nine. Obviously networking in the 80s and 90s really brought that standard up.
