For more detailed measurements,
you can take readings of your phone’s signal in decibels(dB). Decibels are measured in the
negatives and generally should fall between -40 and -130. A score closer to zero indicates a stronger signal. For example, a
signal of -120 dB indicates no service, while a score of about -50 dB means you have excellent signal.
For specific dB signal measurements, use the methods below.
•
iOS - First turn off your Wi-Fi, Next, open the Phone app an dial *3001#12345#* then press the call button. This will open
the Field Test app. Once open, menu navigation varies depending on iOS version, as well as, carrier and iPhone model;
however these instructions should get you to the right place.
•
iOS 14 and later: Navigate to LTE in the menu list then tap on Serving Cell Meas. The measurements that read
“rsrp0” and “rspr1” are your cellular signal strength in decibel-milliwatts.
•
If you’re using an earlier version of iOS, we have more information available here: https://blog.surecall.com/enter-

Android devices: Download the app “Network Signal Info” in the Google Play store.
Step 2. Install the Outside Yagi Antenna and Outside Amplifier
Once you have identified the area of strongest signal, choose where you will mount your outside antenna and outside amplifier
while considering the following factors:
1.
The mounting area must have at least a 3 ft radius clear of obstructions, other radiating elements and metal objects such
as pipes or metal siding.
2.
Both components should be mounted on a pole or pipe (not provided), at the highest possible location above the
roofline – at least 25 vertical feet above the planned location for the indoor antenna.
Note there are two main outside components -- a Yagi directional antenna and the outside amplifier.
Warning: Do not collocate antennas or operate the outdoor antenna with any other antenna or signal booster.
