Introduction to 10 dBi Antennas
A 10 dBi antenna is a type of antenna that has a gain of 10 decibels relative to an isotropic radiator. The gain of an antenna is a measure of its ability to concentrate the signal in a specific direction, resulting in a stronger signal and improved coverage. The higher the gain, the more focused the signal, and the farther it can travel. A 10 dBi antenna is considered a medium-gain antenna, offering a good balance between range and coverage.
Understanding Antenna Gain and Range
The range of a 10 dBi antenna is influenced by several factors, including the frequency of operation, the environment, and the presence of obstacles. In ideal conditions, with no obstacles or interference, a 10 dBi antenna can provide a range of up to several miles. However, in real-world scenarios, the range is often limited by the presence of buildings, trees, and other obstacles that can absorb or scatter the signal.
