Look at it this way. Take a telescope. To see something you have to aim the telescope in the right directiion AND the right angle to see something . Same for antennas.
Um... I'm no expert at telescope/antenna aiming... but isn't the direction and angle the same thing?
I' m not an expert on telescopes terminology.
But in radio usage, direction is the horizontal or compass direction of the antenna. Usually 360 degrees.
Angle is the vertical or up and down tilt of the antenna.. Usually 90 degrees.
For example an antenna might be pointed north in a direction of 0 degrees and tilted upward at an angle of 45 degrees.
I remember something from some old navy history books. Old manually operated anti-aircraft guns.
A gunner who did the actual firing of the gun.
An operator who turned the gun in a horizontal motion (Direction)
An operator who turned the gun in a vertical motion-up and down (Angle)
I'm a little rusty on this but I think they where called gunner, poiinter and trainer. Have to some research on this.
