CM2500W Amplifier - Installation Manual

• Splitter loss (SL): This is the signal loss caused

by a splitter (used if you are installing multiple

antennas).

• Amplifier gain (AG): Number of decibels of

amplification provided by the amplifier (rated

gain less any attenuation, as described in

Chapter 5 of this manual). This is always a pos-

itive number.

The signal strength S at an interior antenna equals

OSL+OAG+IAG+CL+SL+AG. To calculate the

approximate coverage distance of each antenna:

1. Calculate the signal strength S for the first

interior antenna using the preceding formula.

SL 2500MHz WiMAX

2-way -3

3-way -5

4-way -6

2. Find the signal strength S for the antenna

along the bottom of the graph on the follow-

ing page.

3. Move straight up the signal strength line to

the PCS and cellular curves.

4. Read the approximate coverage radius on the

left.

3.6 - Amplifier Location

Select an indoor location for the amplifier that

meets the following criteria:

• Wall or ceiling mounts are acceptable.

• Near a properly grounded 110VAC outlet.

• Not in a tightly enclosed or overly hot space.

• All power and warning lights easily visible.

• Least amount of cable to connect all antennas.
