How it Works
RF Signal
Wilson Electronics 12.5 dB, 1800/1900 MHz, Yagi Antenna will collect the cell tower
signal and send it through the cable to a Signal Booster or directly to the cell phone
or cellular data card. When the cell phone or cellular data card transmits, the signal is
transferred to a Signal Booster or directly to the antenna and transmitted back to the
cell tower.

Cell Tower
Antenna Adapter
An 18-inch external adapter is required to connect the cell phone or cellular data card
to the Yagi Antenna. The external adapter is cell phone/data card specific and may be
purchased through a local retailer. Refer to Wilson Electronics Adapter Guide to identify
the right adapter for your cell phone or cellular data card. The Adapter Guide is available
through a local retailer. It is also available on our website,, or
you may call Technical Support at 866-294-1660.
Adjusting the Antenna for Maximum Performance
To adjust the Yagi Antenna for best performance, connect it to your cell phone with an
external adapter and a length of cable. External antenna adapters and cables are sold
separately. Put the cell phone in test mode and turn the Yagi in 10-degree increments while
checking the cell phone’s signal level. At each point you may need to wait a 10-30 seconds
as your cell phone updates. To find your phone’s test mode, visit
Signal readings usually appear as a negative number (for example, -86). The larger the
number, the more powerful the signal (-75 is stronger than -84). See graph below.

Antenna Installation
The Yagi Antenna should be mounted horizontally with the elements vertical. The
included mounting bracket is adjustable and will accommodate pipe diameters from
1.25” to 2” (pipe sold separately part#901117). Mount the Yagi so that there is 3 feet of
clearance in all directions around it. Position the Yagi so that it has the most unobstructed
line of sight to the cellular service provider’s strongest signal. If you are using a wireless
Signal Booster, make sure the Yagi is not pointing across your own roof.
Warning: Lightning protection is recommended for all installations, sold
separately (Wilson Electronics Part #859902). Take extreme care to ensure that
neither you nor the antenna comes near any electric power lines.
Important: If you are using a wireless Signal Booster, be sure the Yagi is not
pointing across the building in which you are trying to get coverage. The antenna
should point away from the building to help prevent oscillation (feedback).
Once you have obtained the strongest signal fully, tighten the mounting hardware. After
the Signal Booster and the rest of the system is installed and performing correctly,
weatherproof all connections.
Ultra low loss cable is recommended for lengths 20’ or greater to prevent significant signal
loss. Wilson Electronics offers Wilson 400 ultra low loss cable in several lengths from
20-100 feet. Wilson Electronics also offers a wide range of phone adapters to connect
your cell phone to a Signal Booster or directly to the antenna. To find the adapter for your
phone, visit or call toll free 866-294-1660.
