Question

Quizplus · Accepted Answer

dBm is a way to express power level in decibels relative to 1 milliwatt.

Answer: B
 dB isotropic is a way to express gain or power level relative to an isotropic radiator (hypothetical antenna that radiates power uniformly in all directions).

Answer: G
 Isotropic radiator is a theoretical point source of electromagnetic waves that radiates power uniformly in all directions, used as a reference for antenna gain or power levels.

Note: The other choices are various types of antenna or propagation characteristics that might affect the power level or radiation pattern, but they do not directly provide a relative or absolute measure of power level like dBm or dB isotropic.
