Putting your phone in Field Test mode will also indicate what level of decibels (dB) your phone is currently
receiving. Decibels are measured in the negatives, and a score closer to zero indicates you have a better
signal. A signal of -120 dB indicates you have no service, while a score of about -50 dB means you have
excellent signal strength
For specific dB signal measurements, use the methods below.
• Apple iPhones: Dial *3001#12345#* and press Call. In the top-left corner, a dB number appears instead of
bars.
• Android devices: download the app “Network Signal Info” in the Google Play store.
Step 2. Install the Outside Antenna
After identifying the area of strongest signal, choose the surface where
you will mount your outside antenna.
The location should allow for sufficient separation between the outside
antenna and inside antenna. Vertical separation is preferred as it is
more effective than horizontal separation.
The minimum separating distance recommended is 25 vertical feet;
however, increased separation, up to 40 - 50 ft, may be needed,
especially where vertical separation cannot be achieved.
Outside Yagi Antenna
Before installing a Yagi, or directional antenna, note that the antenna should be mounted on a pole or pipe
(not provided), at the highest possible location above the roofline – at least 25 ft above the indoor antenna –
aimed in the direction of your nearest cell tower. To find the location of your carrier’s closest cell tower, go to
www.antennasearch.com.
Ensure that the mounting area has at least a 3 ft radius clear of
obstructions, other radiating elements and metal objects such as pipes
or metal siding and orient the antenna with the drip hole at the bottom.
Once you have identified your install location, assemble the u-bolt,
bracket, nuts and washers onto a pole (available separately) as shown
in the illustration. Keep the connections loose enough to allow the
antenna to rotate until the optimum direction is found.
Once the outside antenna is secured to a pipe or pole, connect antenna
to one end of the provided SC-400 cable and tighten the connection.
Run the cable along route to planned location of your booster.
