Whats the difference between 0db (unity), 3db, 5db gain?
Boster Kit 0-dB gain antennas radiate more energy higher in the vertical plane to reach radio communication sites that are located in higher places. Therefore they are more useful in mountainous and metropolitan areas with tall buildings. A 2dB or 3dB gain antenna is the compromise in suburban and general settings. A 5dB gain antenna radiates more energy toward the horizon compared to the 0, 2 and 3dB antennas to reach radio communication sites that are further apart and less obstructed. Therefore they are best used in deserts, flatlands, and open farm areas.
0 dBd gain antenna radiates more energy higher in the vertical plane to reach radio communication sites that are located in higher places. Therefore they are more useful in mountainous and metropolitan areas with tall buildings. A 3 dBd gain antenna is the compromise in suburban and general settings. A 5 dBd gain antenna radiates more energy toward the horizon compared to the 0 and 3 dBd antennas to reach radio communication sites that are further apart and less obstructed. Therefore they are best used in deserts, plains, flatlands, and open farm areas.
