AOutdoor ANT Installation
Installation Procedures:
● Procedure locating Best Reception of the Outdoor ANT
a. Best Way:
The users may use a smart cell phone in the test mode and read the dBm (it will be always
negative value and closer to 0dBm is stronger) to find the best reception:
1. One person turn the Outdoor ANT (roof ANT) outside in any direction, stand behind the
outdoor ANT (avoid blocking the reception), wait 30secs (for the smart phone to update its
reception status), the person inside the house (stand in a fixed position and hold the cell
phone in the same direction during the procedure of finding the best reception). Record the
reception power level in dBm
2. The person outside must tune the outdoor ANT 15° away from the original direction per step
and await 30 secs per tuning, let the person inside the house record the dBm value.
3. Repeat step 2 per tuning direction in 15° separated from the left to the right direction and
record the dBm value of each tuning direction.
4. Find the direction of the highest dBm reading and fasten the outdoor ANT. Use a tape to seal
the coaxial cable, RF Adaptor and the outdoor ANT’s connector for waterproof. (see P.6)
※Reference dBm reading versus communication quality:
2G MODE

b. Additional Way:
The users may use the bar indicators of the cell phone to find the best reception:
It is entirely the same procedure as the step 1,2,3,4 of “Best way” to find the direction of best
reception as represented above . Choose the indicator with the most amount of bars for the best
reception and fasten the outdoor ANT with sealing tape for water proofing. (see P.5)
※Bar Reception versus communication quality:
Excellent reception
Good reception
Usable, fluctuation, smaller indoor service area
Usable, fluctuation, very small indoor service area
Poor, hard to make a phone call or reception
BCoaxial Cable Installation
The connection of the outdoor ANT with RF adaptor AD-N1F0-06 and the F(M)
connector of the RG-6/U coaxial cable must be sealed by the sealant tape to prevent
corrosion by rain water or melting snow.
Wind back over the second layer of the
sealant tape.
WINDING BACK
The users may use the long coaxial cable 33ft (10m) for installation, the 17ft (5m)
coaxial cable is an extension cable for longer cable path application (optional).
Stop here, wind in the reverse
over the first layer of the
sealant tape.
START HERE
WINDING DIRECTION
※Make a Ushape path when the coaxial cable enters into the house to prevent the
rain water from dropping along with the coaxial cable.
※Do not allow the coaxial cable to curl upon entry, it may cause instability and the
booster loop oscillation.

CIndoor Antenna
DMinimum Separation Distance Limitation
● Allow more than 20ft (6m) direct separation distance between the outdoor ANT and
cell booster to avoid the loop oscillation to cause the booster to shut down with any
1 or 2 blinking LED.
● The users must remove the DC plug from the DC jack of the cell booster
immediately and tune/adjust the outdoor ANT direction/location. You may need to
lengthen the direct distance between the outdoor ANT and cell booster. Re-plug the
DC plug to the DC Jack of the booster as reset , verify these 2 LED lit solid red
and/or green.
● Verify that the 2 LED lights are lit (red or green), not blinking (LED solid lit is a must
requirement for this booster in normal operation).
● If it is still blinking in any 1 or 2 LED , the users must remove the DC plug from the
DC jack of the cell booster, repeat tuning/adjusting the ODANT for each cycle, then,
reset the DC power of the cell booster until the 2 LED lights indicate solid red
and/or green.
● The users may further tune/adjust the direction/location to find the best reception.
(see P.4)
RECOMMENDED NOT RECOMMENDED
※ Remain 135° from the cell booster for better service coverage and system stability.
※Leave the mainunit away from the window and remain more than 20ft (6m) direct
seperation distance from the outdoor antenna to avoid the cell booster’s loop
oscillation.
ELED Indication
● At any condition, the 2 LED lit remains solid Red or Green which represents the
cell booster in normal operation.
Solid R LED: The outdoor ANT captures insufficient outdoor cell tower signal level,
smaller indoor service area. If far away for cell tower, it could be solid red only.
Solid G LED: Sufficient outdoor cell tower signal level was captured by the outdoor ANT,
larger indoor service area improving the service quality both voice and mobile internet.
● If any 1 or 2 LED lights are still blinking , either red or green must be avoided:
R LED blinking: Loop oscillation shuts down the cell booster and no longer enhance the
reception, the troubleshooting procedure see P.9.
G LED blinking: The outdoor ANT captures excessive signal level, and shuts down the
cell booster. Generally, indicates the house is near the cell tower. The users must
tune/adjust the outdoor antenna direction/location away from the cell tower to prevent the
excessive reception. (See Abnormal operation of troubleshooting, P.10)
and 3rd Q&A of frequently asked questions, P.11)
※To tune / adjust the outdoor ANT direction / location to allow the 2 green lights to
become solid which allows the best reception both voice and mobile Internet and larger
indoor coverage. (Detailed tuning procedure see P.5)
※In fringe area, the cell booster may still be 1 or 2 solid RED LED even after after
carefully tuning/adjusting the outdoor ANT, that is the users allocation is far away from the
cell tower for the RED LED band.
Anyway, operationl status in solid RED LED, the users must still tune/adjust the
outdoor ANT direction/location to get a better reception. (Better service quality
and larger indoor service coverage in the fringe area.) (see P.5)
Q: How will the weather affect to the cell phone indoor reception?
A: Sunny or cloudy day will not affect the indoor reception. Rainy, snowy, foggy day
will reduce the indoor reception coverage, especially heavy rain, snow, fog may affect
more. Also, the rain, snow, fog has more influence on PCS Band for its higher
propagation loss than cellular band.
Q: Why the loop oscillation is the most important issue for a cell booster
installation? How can I verify and prevent from it?
A: The loop oscillation not only causes the cell booster to no longer serves the user’s
link and not enough distance separation between the outdoor ANT and booster.
The users may check the 2 LED on the booster as the status indication of loop
oscillation. Any 1 or 2 of the RED lit is blinking indicates loop oscillation of the cell
booster. Remove the DC-plug from the DC jack of booster immediately, and follow the
improvement procedure shown in P.5 or 6 until these 2 LED lit either solid Red or Green.
Q: If my house is nearby the other operator’s cell tower and my cell operator’s tower
is far from my house. How can I install and prevent the excessive signal level coming
from the nearby cell tower?
A: First, you should turn away the outdoor ANT direction from the nearby cell tower
and choose another direction/location, also, by using the house wall as the blockage of
the nearby cell tower.
Q: Can the cell booster serve multiple users simultaneously?
A: Yes. The booster is designed for the multi-users operation for it is linear
amplification and controls the overall power as well as blocking the interference of the
cell tower.
Q: Can the cell booster help Wi-Fi reception?
A: No. It cannot help the home Wi-Fi reception for they are different frequency band
between the cell band and Wi-Fi band.
Q: Does this cell booster help 4G700 and AWS band?
A: No, the cell booster only helps 800 (cellular) and 1900 (PCS) band.
All the mobile operators in 800 and 1900 band may be increased the reception inside the
house by this booster.
Q: Is the cell booster helpful or harmful for human health?
A: It is helpful for human health by installing the cell booster.
The cell booster makes the cell phone radiates lower RF power to cell tower than not
using a cell booster inside the house. The lower RF power radiated from the cell phone
is not only helpful for human health also extend the battery life span.
Q: Why do we use a panel ANT instead of an omni-directional ANT?
A: The panel ANT is a directional ANT which captures more cell signals from tower
than the omni-directional ANT. That makes the panel ANT offers better service quality
and larger indoor service area.

link and not enough distance separation between the outdoor ANT and booster.
The users may check the 2 LED on the booster as the status indication of loop
oscillation. Any 1 or 2 of the RED lit is blinking indicates loop oscillation of the cell
booster. Remove the DC-plug from the DC jack of booster immediately, and follow the
improvement procedure shown in P.5 or 6 until these 2 LED lit either solid Red or Green.
Q: If my house is nearby the other operator’s cell tower and my cell operator’s tower
is far from my house. How can I install and prevent the excessive signal level coming
from the nearby cell tower?
A: First, you should turn away the outdoor ANT direction from the nearby cell tower
and choose another direction/location, also, by using the house wall as the blockage of
the nearby cell tower.
Q: Can the cell booster serve multiple users simultaneously?
A: Yes. The booster is designed for the multi-users operation for it is linear
amplification and controls the overall power as well as blocking the interference of the
cell tower.
Q: Can the cell booster help Wi-Fi reception?
A: No. It cannot help the home Wi-Fi reception for they are different frequency band
between the cell band and Wi-Fi band.
Q: Does this cell booster help 4G700 and AWS band?
A: No, the cell booster only helps 800 (cellular) and 1900 (PCS) band.
All the mobile operators in 800 and 1900 band may be increased the reception inside the
house by this booster.
Q: Is the cell booster helpful or harmful for human health?
A: It is helpful for human health by installing the cell booster.
The cell booster makes the cell phone radiates lower RF power to cell tower than not
using a cell booster inside the house. The lower RF power radiated from the cell phone
is not only helpful for human health also extend the battery life span.
Q: Why do we use a panel ANT instead of an omni-directional ANT?
A: The panel ANT is a directional ANT which captures more cell signals from tower
than the omni-directional ANT. That makes the panel ANT offers better service quality
and larger indoor service area.

Q: How will the weather affect to the cell phone indoor reception?
A: Sunny or cloudy day will not affect the indoor reception. Rainy, snowy, foggy day
will reduce the indoor reception coverage, especially heavy rain, snow, fog may affect
more. Also, the rain, snow, fog has more influence on PCS Band for its higher
propagation loss than cellular band.

Safeguard Features
Anti – oscillation:
If the Outdoor ANT and Indoor ANT of the cell booster installation is not enough
distance separation which may cause loop oscillation.
The cell booster will generate an unwanted interfered oscillation signal , the circuit will
detect this signal and soon to shut down.
The shut down not only protect the cell booster away from damage , also, eliminate
the interference to the tower.
AGC and power control / power down
To prevent from both the excessive UL and / or DL cell signal which may cause the
interference and damage, The AGC circuit of both UL and DL CKT will control the
excessive incoming signal level.
Note that the UL AGC circuit will power down (mute) the UL C.K.T instantaneously
which caused from the short distance separation from the Indoor Antenna, it gets
normally operation while the users remain a certain distance away from the Indoor
ANT immediately.
And the DL AGC circuit shuts down the DC power caused from nearby/toward tower
signal permanently until the users adjust / tune the outdoors’s allocation / direction
and re-set the DC power again for normally operation.
Noise – power limiting
The cell booster will shut down the UL and/or DL power output to avoid the
interference of the cell tower which the cell booster is in condition:
● Loop oscillation
● The Outdoor ANT is toward/nearby the cell tower
● The users is very close to the Indoor ANT of the cell booster
● The ULCKT is in inactictivated mode (power down and awaiting next incoming call
activted)
Variable Gain
The cell booster will reduce the both UL and DLCKT Gain and power output while
nearby the cell tower automatically or nearby the indoor ANT for preventing from the
interference to the cell tower.
