Radiates and receives radio waves in ALL directions. - (ANSWER)Omni-directional
Radiates and receives radio waves in ONLY ONE direction. - (ANSWER)Uni-
directional
Radiates and receives radio waves in TWO directions. - (ANSWER)Bi-directional
The process by which electromagnetic waves are bent so that they appear behind
an obstruction. - (ANSWER)Diffraction
The property of radiating more energy in some directions than in others. -
(ANSWER)Directivity
The increase in signal strength that is produced by an amplifier. - (ANSWER)Gain
The measure of how difficult it is for current to flow through a conductor. -
(ANSWER)Impedance
Random pulses of electromagnetic energy generated by lightning or electrical
equipment. - (ANSWER)Noise
, The turning back of a radio wave from an object or the surface of the earth. -
(ANSWER)Reflection
The bending, or changing direction, of a radio wave passing into or through layers
of the atmosphere or the ionosphere that have different density (dielectric
constant). - (ANSWER)Refraction
The property of material or substance to oppose the passage of current through
it, thus causing electrical energy to be converted into heat energy. -
(ANSWER)Resistance
The state or frequency of vibration, electrical or mechanical, in which forces that
impede the motion are minimum. - (ANSWER)Resonance
Is the area that starts when the ground wave ends and continues until the sky
wave hits the earths surface. - (ANSWER)Skip zone
The angle measured from the earths surface or horizontal up to the direction of
propagation towards the ionosphere. - (ANSWER)Take off angle
Near Vertical Incidence Sky wave allows for decreased skip zones and is extremely
beneficial when operating in complex compartmentalized terrain. NVIS in theory
allows for successful communications in distances ranging from 10-300 miles. -
(ANSWER)NVIS
