Just a thought, as you are in southern hemisphere, wouldn't you see more birds facing North?

Instead of fixing something on the house, I've attached a couple of antenna to the top of one of my washing line poles in the garden as this faces South (I'm in the Southern Hemisphere) and I get an average of 7-8 sats every day and up to 12 at night. It makes any maintenance easy, if you get any snow it is easy to clear at that height, there is much less windage if your subject to strong winds and, if you don't use your washing line, the size of the poles make them quite rigid so you don't suffer a lot of noise that you would high up on a thin pole. Just a thought. Steve On 3 September 2010 12:46, Charles P.
