Skew Angle and Effective Aperture of an Airborne Antenna
Skew angle is a difficult concept to grasp, but the effect can be profound.
Low-profile antennas installed on the top of an airplane fuselage introduce special challenges.
Second generation antennas just entering the market sit flat, creating a change in gain and beamwidth as a function of the relative elevation of the target satellite.
Skew angle rotates the beam-pattern as shown above for various antenna types, at both zero and 90 degree skew.

| How can a UAV safely delivery packages? |
Are the FAA UAV (unmanned aerial vehicle) (or drone) rules taking too long and are they too restrictive?
It is not possible for an operator (remotely) to overcome all the risks of a UAV when overflying a community...
...since the failure we are concerned with most is loss of control.
