2.4 Ghz Antennas It Does Work!!! Will A 14Dbi, 2.4 Ghz Antenna (for Wireless Internet) Transmit A Distance Of 5000' (no Obstructions Between)

Will a 14Dbi, 2.4 Ghz antenna (for wireless internet) transmit a distance of 5000' (no obstructions between) - 2.4 ghz antennas it does work!!!

Is there a standard way, the distance from a transmitting antenna that gives you about the status of the antenna (where calculate no obstructions between the antenna and power supply)?
Thank you,
