PRO 10K SL ZBC745SL Manual
7
The zBoost PRO 10K SL ZBC745SL includes 2 coax
cables, 50 ft. for External Antenna and 15 ft. for Indoor
Antenna.
Connect one end of the cable to the base of the External
Antenna. Run the coaxial cable along a descending pipe or
through a wall that leads closest to the location of the Base
Unit. Connect the remaining end of the cable to the Base
Unit.
Use the 15 ft. coax cable, along with the TNC-F adaptor,
to connect the Indoor Antenna to the Base Unit. See Base
Unit Assembly picture above.
Should you need additional cable length, 15 foot
extensions (Part #: YX030-15w) are available at www.
zBoost.com. Please note: Cable longer than 65 feet is not
recommended.
FOURTH: Connect zBoost Base Unit to Power
Connect the zBoost Base Unit to the power supply and plug into a power outlet. When your zBoost
system is in place and fully connected, walk throughout your home and verify that you are able to
reliably place calls. If the signal strength has improved, your zBoost is working.
Upon initial power up, the LED will cycle RED, GREEN and ORANGE for 30 seconds. After 30
seconds, a series of GREEN ashes will indicate the quality of your setup. Following this, a solid
GREEN light indicates normal conditions. If it is not solid GREEN, follow the instructions in the
Base Unit LED Indicators section. Adjustments may be needed to optimize performance. If you nd
the increased signal coverage is acceptable, however, no additional adjustments are needed. See
“Base Unit Light Indicators” on page 11 for more information.
Antenna Aiming
To get the maximum benet, you will want to take special care to make sure you point the antenna
in the direction of the best signal for your wireless service provider. You may wish to use a YX699
RF signal meter to help during this process or try our zBoost Signal Finder Android App. The
majority of the time a cell tower will hold more than 1 frequency band and/or service provider.
To aim the antenna for maximum signal, you will need a phone operating on the same wireless
network(s) in use at the install location.
Note: A 1 dBm increase is 25% gain in signal strength.
If you do not know which direction the best signal is coming from, once the unit is installed, rotate
the External Antenna in 90 degree increments while measuring the results inside the desired
coverage area.
1. Place the cell phone(s) on a non-metal surface about 6-8 feet from the Base Unit.
2. Turn the signal booster on and wait 30 seconds. Note the number of signal bars displayed
on your cell phone. For best results, you want to place your phone where the phone’s signal
meter displays in the middle of the signal meter range or less so that it can indicate as you
rotate the External Antenna to the optimum direction. If it is reading too high, move the phone
farther from the Indoor Antenna. (Note: if you’re using signal bars to measure signal strength,
turn off your LTE during this process)
3. Record the number of signal bars or dBm________(A) on your cell phone. You can use our
YX699 RF Signal Meter or an application on a smart phone to get the dBm. Leave the phone
in exactly the same place and pointing in the same direction for the following steps. Note the
direction External Antenna starting position ________________.
