122 AWE 120-24 Installation & Configuration Guide
Selecting Antennas
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?
