Safety Information
Congratulations on purchasing the SuperHalo, the finest cellular booster available!
The SuperHalo adjustable cellular boosters and kits remove the frustration over
dropped calls, limited range, and slow data rates by amplifying incoming and outgoing
cellular signals in watercraft of all sizes. The SuperHalo is designed with leading-edge
technology to detect and amplify weak incoming signals your cellular device would
otherwise miss and to broadcast a significantly stronger signal back to the cell tower.
This guide contains all the information you need to get your SuperHalo booster system
up and running.
BEFORE USE, you MUST REGISTER THIS DEVICE with your wireless provider
and have your povider’s consent. Most wireless providers consent to the use of
signal boosters. Some providers may not sp. consent to the use of this device on
their network. If you are unsure, contact your provider.
Theory of Operation
The SuperHalo is a high-quality bi-directional booster that boosts cellular signals for
areas prone to weak cellular coverage.
The SuperHalo is a tri-band cell booster, increasing signal for 2G-3G voice and 4G
The SuperHalo works with two antennas:
An inside antenna that communicates with your cell phone.
An outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplified by the
booster and then sent to your phone via the inside antenna.
When your phone transmits, the signal is sent to the inside antenna and then sent to
the cell tower via the outside antenna.
Some cell signal is required for the SuperHalo to enhance cellular signal coverage. The
weakest cell signal for the SuperHalo to work is low -100dBm to high -90dBm. dBm is
an abbreviation for the power ratio in decibels of the radio power per one milliwatt.
To measure your existing cell signal on an Apple iPhone, dial *3001#12345#*and press
Call. In the top-left corner, a number appears instead of bars.
For Android devices, you can download several apps to measure exact signal
strength. In your phone's App Store, search for "check real signal strength" to find a
cell signal measurement app.

Configuring Gain Settings
1. Facing the front of your booster, find the following
dials starting from the top:
A. LTE-A (AT&T 4G)
B. LTE-U (Verizon 4G)
C. Cellular-800 (All Carriers 2G/3G)
D. PCS-1900 (All Carriers 2G/3G)
E. AWS (T-Mobile 4G)
2. Set these dials according to the coverage area
and the distance between the inside and outside
3. Inside panel antenna provides up to 1,500 square
feet of coverage, or a 25 ft. wide by 100 ft. deep
marine craft.
Adjust dB Gain according to table below if you cannot achieve maximum separation.
Required Between
Outside and Inside Antenna
• 50dB
• 47dB
• 44dB
• 40dB
8-10 ft. separation
5-7 ft. separation
3-4 ft. separation
1-2 ft. separation
Note: As you can see from the table above, acquiring the recommended inside and
outside antenna separation optimizes coverage significantly. Panel antenna can be
vertically installed 6 ft. under outside antenna with the booster at full dB gain.
Inside panel antenna should face away from outside antenna. If panel antenna faces
outside antenna, the booster will oscillate and go into Auto Shutdown.

The Galaxy 5239 is a full-band antenna, built specifically for marine use, it is weather
Antenna Galaxy 5239 - Installation Instruction
OPTION 1 ( Recommended )
1. Choose a mounting location that is as high as feasible, as free as possible from
obstructions, and as far as possible from other antennas and strong sources of RF
2. Before mounting base, drill a hole in the middle of the mounting location wide
enough in diameter to allow CM240-M cable with FME connector to go through.
3. Hand tighten the antenna base to the ferrule.
4. Feed cable, N connector end first, through bottom of base and through hollow
5. Hand tighten N connector to outside antenna and antenna to ferrule.
6. Feed cable, FME end first through the drilled hole.
7. Mount base (screws not provided) and hand tighten ferrule to mount base.

Step 3. Connect the interior Antenna
A : Standard Wireless Usage - ( Recommended ) - CM248W-M
This CM248W full band panel antenna is a compact directional antenna designed to
cover 2G/3G/4G and WLAN systems for Cellular, PCS, AWS and LTE frequencies. It’s a
high gain indoor antenna suited for places where the signal needs to be broadcast over
a wide area. This interior antenna transmits and receives signal to cell phones.
Antenna CM248W-M - Installation Instruction
1. Choose location for mounting antenna on vertical surface. Ideal height from the cabin
deck or floor should be the approximate height of cellphone use.
2. Using plate, mark position of desired placement with pencil or marker.
3. Screw ( not supplied) mounting plate into place with the slide panel protruding
towards you. Provided plastic anchors are only to be used in sheetrock installation.
4. Slide antenna securely onto mounting plate.
5. Use the other CM240-M cable to connect CM248W-M to “inside” of the booster.
Note: Be sure to provide enough separation from outside antenna. Panel antenna
should not face outside antenna.
B : Low Profile Usage - (Optional ) - CM110W-M
1. The patch antenna is intended for indoor
use only. Do not mount on a surface
within 4” of metal.
2. Screw the patch antenna cable to
the connector marked "inside."
Note: Laboratory tests show that patch antenna can work
as close as 2 ft. from outside antenna if the patch antenna
is facing away from outside antenna. If booster shows oscillation,
turn it down by 3 dBs on the dial of oscillating band.

Step 4. Booster Mount
If mounting booster, mount on vertical location using booster screw fittings.
Step 5. Connect to DC Power
1. The positive red and negative black wired end will connect to watercraft’s power
supply-either battery, ignition or fusebox – whichever is located most conveniently.
2. Connect the DC power cord to the booster.
Turn on switch on power cord.
The Power LED goes ON to show that the booster is ready for use.
The Alert LEDs flash up to 15 seconds on each band to show the band is
place parallel with text above.
If the Power light does not go ON, be sure the power supply is working.
If the Alert LEDs flash after the initial activation period, lower the dial above the blinking
LED by 3dB (for example, from 50 to 47) and monitor the bars on your cell phone to see
whether reception has improved.This process can take a few moments. Monitor the
LEDs to make sure they go off.
If the Alert LEDs continue to flash, the booster will shut down automatically to prevent
oscillation, then restarts after 60 seconds.Turn down the Cellular-800 or PCS-1900 or
LTE(AWS) dial to prevent the booster from shutting down again. Fail to do so, booster
will completely power off after 15 minutes. Manual power reset requires powering off
booster and powering back on. Failure to do so will cause the booster to power off.
Note: While the watercraft is in port, the alert light may light up red. This means
that the signal coming into the booster is too strong and it may cause the booster to
shut down. As you move out to sea this will no longer be a problem.
