There's no easy answer to this. I went through the same exercise before I
bought
this QTH.
Just some more questions:
- What direction is the hill ? Is it an important contest direction that you
would expect low-angle signals to come from, such as Europe or Japan ? Or is it
toward VP6 ? Or is it towards the USA, where signals would (probably) come in
at
an angle above 5 degrees ?
- Is your antenna at a height that it will have any significant radiation below
5 degrees ?
Personally, I set the bar at 3 degrees. I think that 5.8 degrees is too high in
a critical direction (EU, JA). There will be some (but not all) openings where
signals may arrive below that angle.
