dBi (decibels relative to isotropic) is a logarithmic unit of measure that expresses the gain of an antenna compared to a theoretical isotropic antenna that radiates energy uniformly in all directions.
Imagine a light bulb that shines in all directions equally. If you put a reflector on it so the light concentrates in a single spot, that light will be much more intense there. The dBi measures how much extra "strength" the signal gains by focusing it in a specific direction instead of wasting it everywhere.
| Attribute | Specification |

| Reference | Isotropic radiator (0 dBi) |
| Scale Type | Logarithmic |
Directivity and Energy Focus
A higher dBi value does not mean the antenna produces more energy, but rather that it redirects existing energy more precisely, narrowing the beam angle to reach greater distances.
Advantages
- Increased range for wireless links.
- Reduction of side and rear interference.
- Better signal-to-noise ratio in the main direction.
A higher dBi value indicates a more directional and longer-range signal.
