What is coverage area for 1 dbi antenna?

The coverage area of a 1 dBi antenna is influenced by several factors, including its gain, the environment, and the frequency of operation. Generally, a 1 dBi antenna provides a modest gain over a theoretical isotropic radiator, resulting in a relatively limited range, typically a few hundred meters in open space. However, in urban or obstructed environments, this range can be significantly reduced due to obstacles and interference. For precise coverage estimations, it's important to consider specific use cases and conditions.
