Hello, I’m trying to find a good antenna to extend the range of my wireless network. I don’t know how to choose one. What im trying to figure out is the maximum distance that a particular antenna can radiate signals according to its transmitting power, antenna gain, and frequency. For example im looking at an antenna with a power input of 200mW and a 7dBi gain at 2.4GHz. That is all the information that the manufacture gives.
