I will check with neighbours about their reception and see what they say.
not sure what vhf and uhf antennas look like but I have had a look around and of the other houses on my side of the road 4 are a flat square shape that point west (probably tamborine) and three including mine which point (roughly) the same direction. the two others are like a ladder (equall length rungs) with a vee at the mounting end and mine has uneven length 'rungs' no vee at the base. these three are horizontal
If yours is the only one with wide "rungs" around 600-700mm across then you might be the only one looking at Brisbane. As for the other two antennas with a vee it sounds like they are UHF if their "rungs" are only around 200mm across.
The flat square one's you think are looking at Tamborine are most likely an antenna called a phased array and they'll have two or four squat looking X's on the front side stacked one above the other if looking at Tamborine.
The one's you describe as being like a ladder, if the "rungs" are horizontal the antenna is installed horizontal.
For the two antennas above to make them used as vertical:
the flat one would be rotated 90 degrees so that the X's are now tall and skinny and side by side.
the one like a ladder would be turned 90 degrees so the rungs are straight up and down.
The "rungs", which is a nice way to describe them are generally called directors and reflectors depending on the design, a term that just about covers everything is to call them elements.
Hope you have good luck with the neighbours.
