[TowerTalk] Takeoff angle

That is a great question! I wish that there was an answer however it varies
which is why many of us have antennas at different heights. I believe that
there was a study showing the probability of different angles on the various
bands from different geographical locations.  Perhaps the ARRL has this or
maybe even it is included with the HFTA program (I never used HFTA).

I've been playing around with HFTA trying to figure out the best height/
configuration for my antennas and it dawned on me I wasn't sure what the
best take off angles are.  I know low is better than high for DX, I'm
assuming it's a range that I'm looking for.
 When looking at the plots what would be considered good take off angles
for DX contests from the  midwest.
What is considered too high of an angle for DX?
