General Repeater Information
Introduction
Almost all of us have experienced a dropped call or “Service Not Available” messages on our cell phones.
This phenomenon occurs because there is inadequate signal strength from the cellular/PCS towers that
provide network coverage. You see the base station cellular/PCS towers along roadsides, on top of
communications towers, and installed on some buildings in urban areas.
Often transmission to and reception from a cellular/PCS tower is weak because the tower is such a long
way away from the mobile unit.

Other times, buildings block the Cellular/PCS signal or make it patchy. Full coverage is quite rare, and due
to “poor reception” we experience interruption of conversations, voice distortion and dropped calls.
The Best Call Cellular/PCS Repeater is the solution to this problem. Repeaters not only amplify the weak
received signal, but they also reduce the need for high level of RF transmission from your cell-phone,
reducing undesirable radiation exposure and battery drainage. The Best Call Cellular/PCS Repeater is ideal
for areas such as offices, apartment blocks and homes where your phone is ordinarily unable to get
adequate reception. By boosting the signal, this device enhances the signal from your handset, ensuring a
reduction in noise and call drops, and so better quality of service.
So how does it work?
Look at the image on the next page to understand the setup of the Best Call Cellular/PCS Repeater kit.
The repeater is made up of two main parts: the directional panel antenna and the Best Call amplifier unit.
The directional panel antenna is aligned with the closest cell phone tower, and collects the Cellular/PCS
signal. This signal is then sent via a 30-foot cable to the Best Call amplifier unit. The amplifier unit boosts
the signal, and then retransmits it about your home or office using a monopole broadcast antenna.

Installing your Best Call Repeater
Site Selection
The first thing you need to do before installing your Best Call Repeater is to find out where you want
to install the repeater. Look at the diagram below for
an idea of how the Cellular/PCS Repeater works:
1. The Cellular/PCS signal is broadcast to/from the Cellular/PCS tower.
2. The directional panel antenna collects the signal from the Cellular/PCS tower.
3. The Best Call Repeater amplifies the signal and re-broadcasts it about your home/office.
4. Ideally, the Best Call Amplifier Unit and the monopole broadcast

Step 1 – Locating the Cellular/PCS Signal
The best way to find the best Cellular/PCS signal around your home/office is simply to walk around
with your cell phone on. You should use a cell phone on the network/band whose signal you are
trying to improve. The “Signal Strength” meter on your cell phone will tell you where the signal is
strongest. Note: The Cell Phone “Signal Strength” meter takes up to 30 seconds to update as you move
from location to location, so make sure to take a nice long pause in every location you test. The place
you choose should either be outside, or in the very least by a window. It should also be within 30 feet
of where you want to rebroadcast the Cellular/PCS signal (this is the length of the provided cable).
Step 2 – Set up the Cellular/PCS Repeater
Once you have established what part of your home has the best signal, you will need to set up the Best
Call Cellular/PCS Repeater.
1. Place the panel antenna in the place with the best signal and connect it to the 30 foot cable.
2. Connect the other end of the cable to the connector on the bottom side of the Best Call
Amplifier Unit (marked “BTS”).
3. Finally, connect the monopole broadcast antenna to the connector on top of the Best Call
repeater (marked “SERVICE”).
4. Move the Best Call amplifier unit inside to where you want the signal to be rebroadcast.
Try to make sure that the directional panel antenna and Best Call amplifier unit are as far away
from each other as possible, and separated by a wall if at all possible. Point 4 above is very
important because it provides isolation between the directional panel antenna and the monopole
broadcast antenna. The two antennas need to be isolated from one another in order to prevent
feedback/oscillation (this occurs when the directional input antenna picks up the signal broadcast
by the broadcast antenna). In order to prevent feedback/oscillation, the directional panel antenna
and the monopole antenna should be distanced from each other, and the directional panel
antenna should always be facing away from the monopole broadcast antenna. It is not vital to
have a wall between the panel antenna and the amplifier unit, but if possible, it can help reduce
the changes of oscillation/feedback occurring.
5. Make sure that the panel antenna is facing in a direction AWAY from the Best Call amplifier
unit.
6. Plug the DC adapter provided with the Best Call package into an electrical socket, and connect
the other end to the “DC in” plug on the bottom of the amplifier unit.
7. The unit’s power “on” light should turn green, signaling that the unit is operating.
STEP 3 - Aligning the Directional Antenna
Now go back to the directional panel antenna. As you turn the panel antenna, the indicator lights will
show the strength of the signal from the direction it is facing. Have someone else stand by the
indicator lights, and tell you which direction provides the strongest signal (highest light level). Make
sure never to turn the directional antenna so that it is facing the direction of the Best Call amplifier unit
(see image below). Depending on the signal quality in your area, you will be able to get a low, medium,

or high strength signal. In order for the Best Call repeater to work properly, you will need to find at
least a medium (5-6 lights on) signal – the “low” signal level is just background signal noise and will not
improve your Cellular/PCS signal.
IF THE “FAIL” LIGHT IS CONSTANTLY LIGHTED:
This means that the input signal strength is too strong, causing what is known as “signal saturation” – this
reduces to effectiveness of the repeater unit. You should change the direction of the antenna to a
direction from which the signal is weaker, such that the “FAIL” light is not constantly on.
IF THE “ALM” LIGHT TURNS ON:
This “alarm” light signals oscillation due to signal feedback. When the alarm Directional Panel Antenna
Positioning light is on, the unit is no longer operation – it will automatically reset after one
minute or you can reset the unit manually by disconnecting and reconnecting the power cable. In order to
prevent the alarm light from turning on, you need to insure the isolation of the directional antenna from
the monopole broadcast antenna. To do this, make sure that the directional antenna is facing away from
the repeater unit and is sufficiently far away. Also, you can improve isolation by installing the repeater
with a wall between the directional antenna and the repeater unit. See the “Step 2” of the installation
procedure above for more information.
STEP 4 - Finalizing the Cellular/PCS Repeater Installation
Once you have found the direction with the best signal, you will need to fix the panel antenna in that
direction. The panel antenna comes with fixtures that allow you to fix the antenna in any direction. Find a
suitable place and install the fixture to a wall or window frame with the four provided screws. The
fixture’s direction is adjustable both horizontally and vertically. Once you have chosen the direction for the
fixture, it can be fixed in that direction by tightening the screw that runs horizontally through the fixture.
Once the directional and position of the fixture have been fixed, the directional panel antenna can be
connected by sliding the directional panel antenna from above onto the fixture. You will hear a click once
the directional panel antenna has locked into place.
Directional Panel Antenna
Finalize the position of the Best Call amplifier unit by making sure that it is in an unobstructed place (to
allow maximum cell phone signal about your home/office). You can also hang the Best Call repeater from
a wall if you wish (a fixture is provided for this on the back of the unit). In general the unit should be
placed approximately at head-height (i.e. 6 feet from the floor). The monopole antenna should always be
fixed vertically. Now you’re ready to enjoy improved cell phone reception. Simply pick up your phone and
make a call!
