i've had a look at that, and do have horizontaly polarised antenna, so i'm assuming (not certain) my main signal is coming from bald knob. Allthough that said i'm also within range of picking up a signal from Noosa/Tewantin, though i have the wrong polarisation for it to pick up a signal from there. Now i'm no TV antenna specialist and i don't really want to have to get up on my roof, but i'm assuming from what it's saying that a normal horizontaly polarized antena should be good enough to pick most things up, and generally it is, as, as i said i can pick up most things except for wins normal digital coverage
