Antenna Radiation Pattern Concern

[darkmagex]

We currently have a Cisco 1200 series with a AIR-ANT2506 (~6dbi) covering a mid size area outdoors. We are looking to be able to connect to a new 1300 bridge that is slightly too far for the current antenna, we were considering replacing with a AIR-ANT24120 (12db) but the 7 degree vertical plane is concerning. The 2506 is a 36 degree vertical.

The antenna is mounted on rooftop and the concern is the signal may be weak on the ground do to the low vertical plane. Is this a valid concern, I'm still working through my understanding of radiation patterns.

Don't worry about the vertical throw too much. As long as you have the antennas far enough away, you should be fine. On the other hand, you could always choose to add a Wi-Fi amp, but that would probably be overkill in your situation.

...and illegal to boot. The equipment as distributed through retail channels is tested and certified to meet the Federal standards for. Users are permitted to replace original components with substantially similar third-party components, keeping the overall system within the designed operational envelope that was certified.

Changing or adding components to "improve" performance by increasing the radiated power are required to be re-certified as operating within the collective applicable laws, regulations, and rules.
