Yagi Antennas
I do not see any noticeable
increase in the bars on my cell phone when I connect it to the Yagi antenna.
There are several reason why
there is no change in signal strength:
-
You do not
have all of the cables hookup and attached properly. Check
all connectors. Make sure the external antenna adapter is
connected to the right port on your cell phone
-
The Yagi
antenna is not pointed at the Cellular Tower. Many people
think that they are pointing at the tower because they can
see it from their home or building. However, you may be
looking at another companies tower instead of the one your
cell phone is hooked up to! Make sure you rotate the Yagi
antenna on the pole slowly pausing every 5 degrees at least
20 or more seconds. This allows the field strength meter
(the Bars on your cell phone) to catch up with the signal
strength.
-
My cell
phone does not increase any bars: The Bars on your cell
phone aren't sensitive enough: Most cell phone signal meters
are not calibrated properly. Each bar m seen on the meter
represent as much as a 15 dB change in signal strength. A 7
dB gain may not even be enough to increase 1 bar! It
is important to note that a 3dB increase in signal strength
translates into double the signal strength and a 6 dB to 4
times. You can essentially be getting 4 times the signal
with no bar increase. The best test is if you can make a
call and if you have fewer dropped calls as well.
-
When I
hookup my cell phone the signal strength shows a drop in
bars: This is most likely caused by a shorted adapter, cable
or if you chose the wrong frequency antenna. It can also be
caused by the cell phone external adapter port
malfunctioning. Disconnect all cables from the external
antenna adapter and unplug the external antenna adapter from
the cell phone. Does the signal level increase? If so, plug
in the adapter. It should decrease if the port disconnects
the internal antenna.
I connected the Yagi Antenna and now I experience
fluctuating Signal levels, it goes to no bars then bounces
to 3 or more bars. When I do make a call, It drops: This is
most prevalent with CDMA type of services such as Version.,
Alltel and Sprint. This can be caused by
-
the
tower being too far away (greater than 25 miles) The
distance problem is as a result of the timing delay of
the signal coming form the tower to your cell phone.
-
a
software problem within the cell phone itself. There are
upgrades available for most cell phones. These upgrades
can installed most of the time by your cellular provider
or dealer.

Tree
Fade: You have trees in the way. You need to place the
Yagi at a different location or on a higher pole to
clear the tree line or other obstructions.
I followed all
of the instructions. I rotated the antenna very slowly pausing
at 5 degree increments for at least 20 seconds. There is not a
tree around me, no buildings to contend with, I have flat land.
All of my connectors are on properly. My cell phone works well
without the adapter plugged in. I upgraded my software on the
cell phone. I am less than 5 miles from the center of a town.
