[QUOTE="condor22, post: 461418, member: 1932"] Re VAST dishes - The Optus C1 satellite is somewhere above E Timor on an equatorial geosynced orbit. So the transmission "beam" at say Cape York is narrow, so you need a larger dish to catch the signal. For most of Central and Southern Australia a good size is the 75 to 80cm dish. When you get down to the south of W.A. the signal divergence is greatest and the dish size can go as low as 35-40cm and collect the signal just as well. It also stands to reason that the nearer the satellite, the less obstruction is tolerated. I've had partial tree branches in the approximate line of sight and still got the signal in Mt Gambier as the signal was broad enough to receive. On the down side, I've also had pixilation when really cloudy and raining hard. My first tripod dish actually came with 2 dish brackets as once in QLD the usual one would not allow enough elevation.
