2.2 Check for signal strength
Before installing the Item#18-850 in your home/office, make sure that you can place calls on
the outside of
your
home/office or in the attic or at roof level where you install the Outdoor
Antenna. The Item#18-850 can only
bring
cell phone signals into your home/office if cell
phone signals are reaching the outside of your home/office,
your
attic or at roof
level. T
he
best way to find the cellular 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. The Cell Phone “Signal
Strength”
meter takes up to 6~10 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.
If you can reliably make and receive calls outside your home/office, then Item#18-
850 can
bring
the signal into your home/office. If only one signal bar is displayed on your
cell phone, indoor coverage
will
be limited to one small room or
area.
Caution
:
Cell Phone Signal bars are approximate and vary for each model of
phone.
The number of bars can fluctuate widely, depending on the
exact location
of
the phone, position or angle of the phone, weather,
etc. Most cell
phone
signal meters update every 6 to 10 seconds. An
increase of only one
bar
typically indicates a 4x
to
10x signal
increase. The best indicator of coverage area is your ability
to
reliably place and receive
calls.
2.3 Determine the Needed Coverage Area
Identify the location in your home/office where you need signal coverage Item#18-850 can
cover approximately 2000 ft. the type of antennas used will dictate the exact coverage area.
Coverage varies based
on
outdoor signal level, building construction, and general installation.
Walls, ceilings or floors
will
reduce the coverage
area.
2.4 Location of Outdoor Antenna and Indoor Antenna
It is recommended that the Outdoor Antenna and Indoor Antenna have approximately 15
feet of vertical separation. If the antennas are too close together, the LED’s will turn RED
indicating Oscillations. Place the Outdoor Antenna as high as possible
to
capture the best
signal.
