Mounting of External Antenna(s)
When you have determined the location of the strongest signal, install the antennas to a mast or j-pole
(Outdoor J-pole Antenna Mounting Bracket, YX014 available at www.zBoost.com). Loosely connect the
antenna(s) to the mast to allow the antennas to be reoriented for strongest signal.
Follow the speci c antenna installation instructions included with the External Antenna.
Omni-directional External Antennas should be placed as high as possible in the area of strongest signal.
Directional External Antennas should be aimed at the cellular tower of the appropriate carrier.
e location of the tower can be determined by using any of the following methods:
1. Using a YX699 Signal Meter (available at www.zBoost.com), connect the signal meter to the antenna
using the cable provided with the signal meter. Rotate the antenna until the optimum signal reading is
determined and secure the antenna at that position.
2. Download the zBoost Signal Finder Android app on a phone using a cell phone operating on the
primary carrier network of the location’s occupants.
3. Go to www.OpenSignal.com. Enter the zip code of the installation site. Note the location of the
appropriate tower.
4. See the Antenna Aiming section of this manual. Once a soft system install is complete, follow the
instructions for aiming the antenna(s)
NOTE: e zBoost YX741 requires at least 15 feet of vertical separation between the Indoor Antenna and
the External Antennas. Generally, increasing this distance (up to 40 feet) will increase the performance and
decreasing the distance will limit zBoost performance.
Antenna Aiming
To get the maximum bene t, you will want to take special care to make sure you point the antenna in the
direction of the best signal for your carrier
To aim the antenna for maximum signal, you will need a phone operating on the same wireless network(s) in
used 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.
e majority of the time, a cell tower will hold more than 1 frequency band and/or carrier. If you are using
two external antennas - one operating on PCS band and one operating on the cellular band, both antennas
will generally point in the same direction.
1. Place the cell phone(s) (in eld test mode) 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 signal reading displayed on the cell phone.
________dBm (A)
3. 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 ________________.
4. Rotate the External Antenna 90 degrees and then record the signal strength. ______dBm (B)
5. Continue to rotate the antenna another 90 degrees in the same direction and record the phone signal
strength. _______dBm (C)
6. Again, rotate the antenna another 90 degrees in the same direction and again record the phone signal
strength. ________dBm (D)
7. If you desire to optimize further, then look for the two highest signal readings above and move the
antenna between these two points to nd the highest signal reading.
8. Look for the highest reading above. Set the antenna to that position and tighten the antenna to
the mast of your choosing. We suggest PVC pipe that is at least 1.5” or J-Pole (part # YX014, not
included).
Installing the Indoor Antenna
zBoost has several indoor antenna options. e dome and panel antennas are the most popular for in-
building applications.
Follow the speci c antenna installation instructions included with the indoor antenna.
e indoor antenna is connected to the base unit using coax cable (see illustration on page 8). A directional
antenna should be mounted on a wall facing the direction where increased coverage is desired. A ceiling
mounted antenna should be placed in the center of the desired coverage area.
Note
Avoid placing the External Antennas near metal such as
wiring, A/C ducts, metal siding, truss plates, etc.
When connecting the cable to the antenna, run the cable
straight down from the antenna. Avoid draping the coax
near the antenna.
