How should I choose the dbi of the Antenna?
How should I choose the dbi of the Antenna? Customers often ask before buying an antenna: Do you have a high-gain antenna here? The higher the better! In fact, the gain effect of the antenna is not higher the more suitable for everyone, or you need to choose according to your own situation. Here is a little tip. 1. Antenna gain Refers to the ratio of the radiated power flux density of the antenna in a specified direction to the maximum radiated power flux density of the reference antenna (usually using an ideal point source) at the same input power. 2. Relationship between antenna gain, pattern, and antenna size Antenna gain is used to measure the ability of the antenna to send and receive signals in a specific direction, and it is one of the important parameters for selecting a base station antenna. The higher the antenna gain, the better the directivity, the more concentrated the energy, and the narrower the lobes. The higher the gain, the longer the antenna length. 3. Several ...
