A dish antenna must face the arriving waves.
A dish antenna must face the arriving waves.
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
Velocity is the derivative of position (in a specific direction) with respect to time.
Velocity is the derivate of position with respect to time (i.e., the rate of change of position). Velocity is a vector (the direction is relevant). If only the number is specified, not the direction, the word "speed" is used instead. Acceleration is the derivative of velocity with respect to time; or the second derivate of position with respect to time (i.e., the rate of change of velocity).
It depends on the usage. With respect to insects it would be "antennae". However, with respect to radio antenna and similar it would be "antennas"
Antenna gain of base station for a specific user depends on antenna pattern, antenna orientation (azimuth and tilt) and user's coordinates with respect to base station.
One Direction ==================== Your question is irrelevant as it describes a state of a substance. It is merely the term for a body's relative change in position with respect to its surroundings. Only physical quantities can have direction. Physical quantities being only the vector quantities.

Because the sun moves through the sky, or at least it appears to do that. Since the sun's position changes with respect to objects on the earth so do their shadows.
6.5 m at 67 degrees north of east
With respect to navigation, a bearing is the direction from one's vessel or aircraft to an object or position. It can also be used as a reference point, such as a line to remain clear (or north or south) of.
