Select Main Unit Location
Use your phone to nd where coverage is needed. This is
where the Server Antenna should be installed on a wall.
Place the Main Unit near a window where there is a
strong signal. Ideally, the Main Unit should be placed with
at least one wall from the Server Antenna and as far as
the cable will allow. If the Server Antenna cable is too
short, it can be extended with a separate coaxial cable
having SMA(m) & SMA(f) connectors.
Attach the Donor Antenna and
Server Antenna to the Main Unit.
Make sure to mount the Server
Antenna horizontally.
Plug in the Main Unit to power with the included AC Adapter. The LED on
the front will blink during set up and turn green when the device is ready.
After powering on the device, connect the Power Cable Clamp.
Download the WAVE App to monitor your system status.
Connect the Main Unit using category cable to your ISP
modem LAN port or external LTE modem to manage via the
web interface WAVE Portal.

App is available for smart-

The Donor Antenna should be separated/isolated as far away as possible from
the Server Antenna, with greater separation providing best performance.

Advanced Installation
For best results, separate the Donor and Server Antenna(s) as much as possible.
Antenna separation (isolation) can be achieved with either physical distance or walls
and oors between the antennas.
Make sure any cables, splitters, and antennas used in the system are properly matched.
(CEL-FI GO G51 is rated for 50 Ω)

Before installing, ensure there are no wires, other objects, or metal plates above the drywall that may interfere
with the inserts, screws, or mounted units.
Mark the four mounting hole
locations with a pencil based
on where you’ll position the
Main Unit.
Determine where to install the Main Unit
based on the recommendations in the Quick
Installation section.
In each marked spot, use a 3/16”
drill bit to drill guide holes for the
Drywall Anchors, and then install
the anchors.
