The GO G41 is manufactured by Cel-Fi, but supported by
Waveform and our team of Signal Specialists.
We’ve helped over 50,000 customers boost their signal since our
company was founded in 2007. We’ve installed and congured
thousands of devices in buildings across the country, and we’re
here to help. If you have any issues at all, please don’t hesitate to
reach out.
About Waveform
We know, reading manuals isn’t fun. But we promise it’s worth it.
We’ve helped hundreds of customers install the Cel-Fi GO G41 and boost their
signal. We’ve compiled everything we’ve learned in this manual.
Give it a read before you start: it’ll save you time and help you get the best
performance out of your GO G41.
The GO G41 is set-up via the Cel-Fi Wave App, please skip the installation
instructions provided within the app and follow this manual instead.

Your kit includes the GO G41 Amplier, the UltraPole Base Kit, a Log Periodic outdoor antenna,
a set of indoor antenna(s), and additional installation components. Depending on which kit
you purchased, your kit may also include contain a Grid Parabolic antenna.
Indoor Antennas, Cables, and Splitters (Depends on Kit Selections)
You will either have 1x, 2x, 3x or 4x dome and panel indoor antennas.
This bit is a little confusing: We include both types of
indoor antennas with each kit. This is so you can use
whichever type of antenna works best in your space.
Once you’re done with your install, you’ll have extra
antennas you can discard.
For example - if you purchased a 3 antenna kit, you'll
receive a total of 3x dome antennas and 3x panel
antennas, but you'll only install three antennas in
total.
You'll also have multiple 30 ft RS400 coax cables. If
you picked a kit with multiple indoor antennas you'll
additionally get a 1 ft jumper and a signal splitter.

Signal boosters can be nicky to set up. The Cel-Fi GO G41 is no exception. It will take a bit of
work to get your GO G41 system installed optimally.
But there’s a reason that most people are willing to take the time to perform an installation,
even if it takes 4 to 5 hours. The GO G41 is the only device on the market that provides an
industry-leading 100 dB of gain. Once you get it set up and running properly, you should see a
signicant improvement in signal, right away.
This manual is based on feedback from hundreds of customers like you. We’ve revised it
dozens of times to make it as helpful as possible. We promise you’ll be glad if you read it
from start to nish before you get started. It’ll help you save time, avoid common pitfalls, and
ensure your system works as well as possible.

Before you start

It’s critical that you have at least 1 bar of usable signal outside or on the roof of the building
you’re installing the GO G41 in. If you don’t have 1 bar, or if you’re not sure, give us a call.
What do we mean by usable?
Well, you need to be able to place a call and use data reliably. A good way to check is to turn
your phone's Wi-Fi off, go outside, visit speedtest.net, and run a test. If your test is able to
complete, you've got usable signal!
Cell boosters bring signal inside from outdoors. If you don’t have 1 bar of usable signal
outside your building, we’re sorry, but the GO G41 likely won't work at your location. Visit
waveform.com/returns to set up a return. We’re happy to take your Cel-Fi GO G41 back and
try to help you nd a booster that might work.
Compatibility
A quick note on compatibility. The Cel-Fi GO G41 is compatible with:
AT&T 3G, 4G LTE and 5G DSS signal on Bands 2, 4, 5, and 12
Verizon 3G, 4G LTE and 5G DSS signal on Bands 2, 4, 5, and 13
T-Mobile 3G and 4G LTE signal on Bands 2, 4, 5, and 12
Worried about 5G? The Cel-Fi GO G41 is the only consumer grade signal booster capable
of relaying 5G-DSS at 100 dB of gain. Additional 5G NR support will be added in 2024 via a
rmware update.
Dynamic Spectrum Sharing (DSS) is used by some carriers to transmit 4G LTE and 5G in a
single “hybrid” channel. 5G DSS Support on the GO G41 is enabled by default on the same
bands listed above.
Unfortunately, the GO G41 cannot boost T-Mobile 5G. T-Mobile's 5G bands are deployed on
bands n71 and n41, which the FCC has not yet approved for boosting in the US.
What do the LAN and USB-C ports do?
The LAN and USB-C ports on the side of the GO G41 are diagnostic ports that can only be
accessed by Cel-Fi Certied System Integrators. The small light is associated with these
ports. No need to worry! Access to these ports is not necessary to setup your system.

Install Process Overview
01
This is the process that we suggest using for installing your Cel-Fi GO G41, each of these
steps is explained in greater detail within the following pages of this manual:
1 Read this manual – Ideally from start to nish so that you understand the whole process
before you begin.
2 Download the Wave app (Page 8) – Visit waveform.com/waveapp on your phone to
download the Wave App, which lets you congure your GO G41.
3 Congure the settings of your GO G41 within the Wave App (Page 8) – Run through
the initial setup in the Wave App to congure your booster. Skip the install instructions
suggested in the app; we're condent that following our manual will lead to a much
smoother installation experience and better performance from your GO G41.
4 Find the best outdoor antenna location and direction (Pages 10-12) – This step is the
most time consuming, but it’s worth the effort. Getting it right has a huge impact on
your system’s performance.
5 ”Temporary install”and indoor antenna positioning (Pages 12-16) – Without making
any holes in your roof or walls, temporarily run the cable indoors to your GO G41, and
nd indoor antenna locations with enough separation from the outdoor antenna.
6 Verify performance and hard-wire everything (Page 17) – Run speed tests and check
your bars – if everything's looking good, it’s time to nalize all your cable runs and
mount antennas.
7 Tell us how your system is doing (Page 22) – We really love hearing how our customer’s
systems are performing. Send us an email and let us know how things look.
If anything’s unclear, or you’re unsure about something, just call us at (800) 761-3041,

One of the most common questions we get asked is: how do I get better data rates?
To understand how to get the highest data rates we need to dig into the details a little. In this
section we'll give you a quick primer on how cell signal works.
a. Signal Bars
Your phone’s signal bars attempt to give you an idea of how
“good” your signal is.
How does your phone decide how many bars to show? Well,
it measures both the signal strength and signal quality, and
converts those measurements into a simple indicator.
Having either low signal strength or low signal quality can limit the number of bars your phone
displays.
For example, you can have a strong signal, but if the signal quality is low, you won’t have many
bars. Or your signal quality might be perfect, but if it's very weak, you still won’t see many bars.
However, the real secret is this: signal bars aren’t all that important.
You can have full bars and very slow data rates. Or you can have 1 bar and super high data
rates. We regularly see both!
That’s why we don’t recommend judging your signal by the number of bars your device is
showing. Instead, use a speed test app to measure your data rates indoors before and after
you install your GO G41.
You can download our favorite speed test app ("Speedtest by Ookla") by visiting this URL:
waveform.com/speedtest
Go ahead and download that speed test app now, and run a couple of speed tests indoors.
You’ll notice that your results will uctuate a little between tests – that’s normal.
If your phone's connected to Wi-Fi, the speed test will measure the speed of your Wi-Fi instead
of your cellular connection. Disable your phone’s Wi-Fi and run the test again.

b. Signal Quality (SINR)
Signal quality is probably the most important measure of your cell signal. In 4G LTE networks,
signal quality is called “SINR,” which stands for “Signal to Interference Plus Noise Ratio.”
In general, the better the signal quality, the faster your download speeds will be. Improving
this measure can have a big impact on your system’s performance.
Why does signal quality drop? It's actually because cell towers interfere with each other.
Every cell tower transmits signal
on the same set of bands.
If you’re located between multiple
cell towers, your phone has a
hard time clearly “hearing” the
cell signal from the tower you’re
connected to. This is called
“intracell interference.”
A signal booster like the GO G41
won’t increase your signal quality
directly. However, by shielding and aiming the directional outdoor antenna that’s included
in your kit you can nd higher quality signal, and the GO G41 will amplify that signal and
rebroadcast it indoors.
We’ll explain exactly how to position and aim your outdoor antenna later in this manual.
c. Signal Strength (RSRP)
The main measure of signal strength for LTE networks is called
“RSRP.” Signal strength is measured in dBm and is always a
negative number.
Signal boosters like the GO G41 amplify your signal so you
have higher signal strength. The GO G41 has 100 decibels of
gain (a measure of amplication). That means that it’ll cover a
larger area with stronger signal than most boosters.
Stronger signal can help you get better data rates and a more
reliable connection. But signal quality is critical as well.

d. Bands
Your cell phone connects to towers on certain ‘frequency bands.” These bands are licensed to
each carrier by the Federal Communications Commission (FCC) in the US.
Each frequency band has a certain “bandwidth” which determines it’s total data capacity. That
capacity is split amongst the users who are connected to it.
In general, higher frequency bands (like 1900 MHz and 2100 MHz) travel less far and penetrate
building materials less well than lower frequency bands (like 700 MHz and 800 MHz). As a
result, higher frequency bands tend to be less “congested” - they have fewer users connected
to them, and data rates are often faster. This isn't always the case though, sometimes a lower
frequency band may have better data rates, depending on your location.
Newer phones have a feature called “carrier aggregation,” which means that they can connect
on multiple bands simultaneously to increase data rates.
The Cel-Fi GO G41 can boost up to 2 bands simultaneously. Depending on the signal
conditions in your area, there may be just 1 cellular band available, or up to 5. After you’ve
completed a provisional install, you can experiment with enabling specic frequency bands to
see if a particular combination gets you the best speed test results.
Unfortunately, FCC regulations don’t yet allow consumer signal boosters in the US to amplify
LTE band 30 (2300 MHz), band 41 (2500 MHz), or band 71 (600 MHz).
Okay, thanks for reading that!
We know that's a lot of information, but we promise it'll be helpful as you start your install. Our
goal is to get you strong, amplied signal and the best possible signal quality on the bands
that get you the best data rates. Let's get started!
Low Frequency Bands
More congested, lower data rates
Travel further, penetrate buildings
700 MHz (Bands 12, 13, 17)
850 MHz (Band 5)
1900 MHz (Band 2)
2100 MHz (Band 4, 66)
High Frequency Bands
Less congested, faster data rates
Travel less far, don’t penetrate buildings

First, connect your GO G41 to power, and download the Wave app to congure and monitor
your GO G41. You won't need any antennas during this step.
1Plug your GO G41 into a power outlet to power it on, don't connect any antennas just yet.
2Download the Wave app at waveform.com/waveapp
3Ensure bluetooth is enabled for your phone (or tablet). The
Wave App requires a bluetooth connection to your GO G41 for
it's conguration and monitoring.
4Open the app with your phone near the GO G41 and select
"I don't need help" to start pairing. Don't worry! We'll walk you
through every step of the installation in this manual.
It may take a few minutes for the GO G41 to connect.
5Once connected, select your operator (i.e. carrier) and press
continue. You can leave all other options unchanged.
For AT&T customers, choose “AT&T LTE Preferred” to ensure that
your GO G41 boosts as many LTE bands as possible.
If you need to boost a different carrier at a later date, go to “Settings” then “Operator”.
Changing carriers takes a few minutes - don’t turn off your booster or move your phone away
during the process.

Troubleshooting Wave App Pairing:
• Only one device (e.g. your phone or tablet) can connect to the GO G41 via Bluetooth at a time to
congure and monitor your GO G41.
• If the Wave app is unable to connect to your device, rst try force-closing the app.
• In Android, this is done by going to your phone’s Settings, choosing the “Apps” option, nding
the Wave app, and then choosing the “Force Stop” option.
• For iOS, you can read here about how to force-close apps:
waveform.com/fcios
• If force-closing the app doesn’t help, restart your phone and power cycle the GO G41 by unplugging
the power adapter.

Understand How The GO G41 Works
04
The GO G41 “Searches” For Signal
Unlike other boosters, the GO G41 doesn’t blindly amplify every frequency. Instead, it searches
for, and then amplies, the best signal available for your carrier.
At any given time, the GO G41 can amplify up to two frequency bands.
Once you've connected antennas to the GO G41, you can watch in the “Activity” tab of the
Wave app as it scans the frequencies on different bands to nd the best signal to amplify.
Anytime you power-cycle the GO G41, change the band settings, or change the operator, it
will restart scanning to nd the best signal. The GO G41 starts scanning as soon as you unplug
the outdoor antenna cable. To make sure it scans all frequencies, restart the GO G41 anytime
you disconnect and then reconnect the outdoor antenna.
Status Lights
The small light on the GO G41 ashes to indicate its current status.
Blinking Red & Green:
The GO G41 is performing its start-up sequence.
Blinking Green:
The GO G41 is scanning for networks to boost.
Solid Green:
The GO G41 has found the best band and is now amplifying service.
Blinking or Solid Red:
The unit is in an error condition. Use the Wave App to check for the Error
Condition Code. Call us for assistance.
Boot-up Sequence
After being plugged in, the GO G41 status light will start blinking red and green, then move
on to blinking green as it starts scanning the cellular frequency bands. Make sure the outdoor
antenna is connected to the port before powering on so the GO G41 can nd signal.
Finally, once the GO G41 has found a signal to boost, the status light will switch to solid green.
