Then why do it if it does not work better?

Pointing an antenna skyward, IF it did in fact change the take-off angle, would simply shorten the skip length your signal would travel. That's the part I was talking about with incident and reflective angles. The ionosphere is like a mirror basically. The signal will leave it at about the same angle it arrives.....basically. The other part about what I said is that at HF an antenna's take-off angle is derived mainly from the height above ground and the quality of the ground under it. Changing the boom angle from horizontal by 5 or 10 degrees will not amount to a hill of beans difference.

You are not really mobile when you set up a base type antenna especially a yagi of any type. Most refer to that type of operation as static-mobile meaning a mobile station set up at a temporary location usually with a base antenna of some sort.
