The first system I had was Direct TV too. The first time I mounted it, (on the 19th floor of my building) I had the dish too high up on the balcony wall...an installer friend came to offer me advice and had me move it down to the bottom of the wall, almost on the floor of the balcony. I thought that the railing would get in the way of the signal but as Tony desribes above, the angle is so high that it clears even though it may look like it will not. Turned out that it was the roof of the balcony that was blocking the signal. Maybe it was moved or bumped since you last tried to adjust it? My Expressvu dish is mounted really solid however I have to occasionally re-aim it anyways...

How about the weather there the last few days? Has high-level precipitation been blocking the signal while you attempt to aim?

Third, is she using a unlooped/pirate card by chance? It seems that here in Canada that our (illegal) Direct TV systems are being zapped on a daily basis now...

I understand that my suggestions may be no-brainers but these are all things I have experienced. I think it saves major frustration when someone says..."gee I never thought of that"...
