4.1.4 Installation Site Survey
Prior to installing the Extended Range Amplified WLAN System, the site platform targeted for
installation must be surveyed for engineering design and installation. Adherence to Maximum
Permissible Exposure (MPE) RF Radiation Hazard distances must be reviewed and antenna locations
planned for minimizing potential RF energy human exposure levels to personnel working in the vicinity
of the amplified antenna location, as well as minimizing any potential co-site radio interference issues.
During fixed site WLAN surveys and analysis, emphasis should also be placed on locating the antenna in
a position that is free of obstructions near the antenna location. Such obstructions include large trees, air
conditioning units, other antenna masts, chimneys, retaining walls, and so forth, as they can significantly
affect the LOS range of the WLAN system. The site survey and resulting plan should take all these
elements into consideration. The fixed site antenna should be mounted as high as possible. The antenna
mast should place the antenna at least 10 to 15 feet above the rooftop or above any obstruction obstructing
the antenna’s line of sight (LOS) signal path. A note should be made of the antennas position, required
mast height, and the type of mounting hardware needed. Antenna-to-Antenna Mast U-bolt mounting
hardware is shipped with the Extended Range Amplified WLAN System and should meet the
requirements for most types of mast installation. The means for communicating with helpers at the
antenna site while conducting link testing should also be planned in advance. For instance, walkie-talkies
or cellular phones would be very helpful during this procedure.
Any necessary routing for the feed line antenna cable must be determined. If the cable extends through
the roof or wall, appropriate waterproof fittings and/or conduit paths must be used. A licensed antenna
specialist or roofing contractor should be consulted to assist with proper cable routing and antenna
installation specifics, as necessary. Electrical power considerations for fixed site installations must be
made in advance for properly installing the extended range antenna system.

4.1.5 Installation Safety and Equipment Warnings
NOTE: Only experienced antenna installers who are familiar with local building and safety codes, and
have been licensed by the appropriate government regulatory bodies wherever necessary, shall install the
antenna system. Failure to do so may void the product warranty, as well as expose the end-user to legal
and/or financial liabilities. Teletronics International Inc., its agents, resellers, or distributors, are not
liable for injury, damage, or violation of government regulations that may arise from failing to comply
with the guidelines described in this document.
