A client has a Cisco Aironet 1300 with a AIR-ANT2506 antenna. I have no experience with this other than maybe 1 hour of poking through the GUI interface but it seems as if the coverage for this device is pretty low. I get reception to the AP up to about 100 yards at which point it drop. The antenna is mounted on the ceiling of a building and I'm testing out in the parking lot. It's a small business so there's only 1 wall between the antenna and the parking lot.
I noticed an option for Antenna Gain. The values are -128 - 128., I suspect this setting could benefit the reception if configured properly. Can someone help please?
