Further, all installations of the Model I WLL Trailblazer System will require

topographic analysis, site survey and link budget calculation. Therefore,

the system will require a CWT trained professional to do the installation.

Marketing and sales channels

CWT DOES NOT sell the Trailblazer PRO direct to end users. I WLL Trail-

blazer PRO System will be sold only to CWT's Authorized Resellers.

Those authorized resellers are technically trained by CWT's Engineers

periodically and must follow the rules set by CWT. The Trailblazer PRO

system is designed for Long Range (15-35 miles) applications and it in-

volves a complicated mandatory site survey, roof top mast installation,

high gain antennas, accurate antenna alignment, etc. Those activities can

be done ONLY by professional installers that are familiar with the FCC

regulations. CWT does not sell the Trailblazer PRO in the consumer busi-

ness at all. We have no resellers in this market and we do not advertise in

consumers based publications or attend consumer oriented trade shows.

The system will be advertised in technical trade shows and magazines.

Conclusion

CWT requires professional installation for the Model I WLL Trailblazer

System in-order to provide the highest reliable system possible. We

therefore fully support the mandate for professional installation of our

complete system.

Rough alignment. This is usually easier then it would seem. Since it is a

prerequisite that you have line of sight between the two points, here are

several ideas that have worked for installers:

(1) If you can see the other unit, simply aim the units towards each other.

(2) During midday, use a mirror or compact disk to create a reflection ap-

proximately towards the other site while someone watches for the flash.

(3) Plot out the path on a topography map and set the antennas using a

compass.

How close in alignment do they need to be? +/- 10 degrees will be

adequate for most paths using the 14 dB gain antenna. Certain paths that

have a low fade margin may require a more accurate setting.

Final alignment. This is usually done by connecting a standard cordless

phone to the FXS or FXO end, and then give a best guess to the direc-

tion, establish a connection and rotating the antennas both right and left

noting the points where the signal disappears, (assuming that it does) and

then centering them between those cutoff points.
