What is the range of 7dBi antenna?
902-930MHz
The antenna has an average gain of 7dBi, a length of 92cm, and a frequency range from 902-930MHz and it comes with hardware for pole and wall mounting.
What does antenna dBi mean?
decibels relative to isotropic
The expression dBi is used to define the gain of an antenna system relative to an isotropic radiator at radio frequencies . The symbol is an abbreviation for “decibels relative to isotropic.” The dBi specification is based on the decibel , a logarithm ic measure of relative power .
What is dBi antenna gain?
The gain of an antenna is simply the measure of an antenna’s ability to direct or concentrate radio frequency energy in a particular direction or pattern, with dBi being the unit of measure. …
How does dBi gain work?
The gain of an antenna is simply the measure of an antenna’s ability to direct or concentrate radio frequency energy in a particular direction or pattern, with dBi being the unit of measure. High gain antennas (8.1 dBi) take the signal and radiate it along a straight plane in a tight, narrow pattern.
