Antenna Radiation Pattern Concern

darkmagex · ‎07-20-2010

We currently have a 1200 series with a AIR-ANT2506 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 but the 7 degree vertical plane is concerning.

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.

If you get a bad signal, find a way to tilt the antenna.
