 AWE 120-24 Installation & Configuration Guide

There are several factors to consider when selecting the right antenna for a wireless application. The 
following are some initial questions you should ask before selecting an antenna.

•

What is the operating frequency range?

•

Will this be a point-to-point or point-to-multipoint application? Ensure that you consider if the 
application will change in the future?

•

What are the coverage requirements?

•

What is the gain requirement?

•

What is the elevation of the remote site(s) with respect to the base station and will additional 
downtilt/uptilt be necessary at either the base or remote site to compensate?

•

Will there be any obstructions in the path?

•

Will systems be co-located? What polarity will be used?

•

What are the regional environmental conditions? For example, is there windloading, salt air, excessive 
moisture, ice buildup etc.?

•

What is the antenna lifetime expectation?

•

What are the site and mounting options?

•

What are the restrictions in the locale regarding the effective radiated power permitted from the 
antenna?

•

Will antenna appearance be a factor?
