Nextivity Cel-Fi GO-X Home & Office cell phone signal booster for US Cellular network is a single carrier signal amplifier kit with industry-leading 100 dB gain. CelFi GOX US Cellular signal booster does not require broadband home Internet service for it to work.

Cel-Fi GO X is a signal booster system that covers US Cellular's frequency bands 2, 4, 5, 12 and 13. It uses Nextivity’s Cel-Fi Smart Signal Booster technology to increase data and voice coverage significantly using already existing signals outside building or house. Signal Amplifier Model # G32-2/4/5/12/13X, G32-2451213X, G322451213X. Band 2/4/5/12/13 - US Cellular. SKU: 590NG32GWUS5UCUS1TF1. UPC: 697691004518.

This Nextfi version of the Go X is programmed to work only with US Cellular phones but it provides an amazing amount of gain at 100dB. The cellphone service provider can be switched to select other using the Cel-Fi switching app, but it will amplify signals of only that one service provider at a time. As it is not a broadband (multi-carrier) device, the FCC does not restrict its gain to 70 dB. The Go X is NEMA 4 certified, making it weather resistant and suitable for installation outdoors.

Nextivity Cel-Fi GO-X US Cellular Band 2/4/5/12/13 provides additional 30 dB gain compared to broadband models makes the Cel-Fi Go X ideal for buildings where outdoor coverage is weak (-80 dBm RSRP or less than 3 bars).

It is ideal for boosting 3G, 4G, LTE signals within urban residential and business structures like small buildings, apartment complexes, and skyscrapers with poor signals inside. It is also ideal for housings in rural and remote places such as cottages and cabins with weak signals inside.

Benefits:

• Works for all US Cellular phones & cell devices.
• No monthly fees and no broadband Wi-Fi service required.
• Industry-leading design and performance by Nextivity Cel-Fi.
• Complete signal booster kit with chosen antenna combination: All parts included and easy installation instructions included.
• Boosts 3G and 4G LTE signals in any type structure - Home, Office, Apartment, Building, Cabin, or Warehouse.

CelFi GoX can be used in numerous applications, including:

• Businesses.
• Homes.
• Hospitals.
• Retail outlets.
• Industrial facilities.
• Warehouses.
• Outdoor facilities.

Cel-Fi GO X warranty period is two years from the date of purchase. Note that this model Cel-Fi GO X is programmed to boost signal for U.S. Cellular networks but you can change to any carrier in seconds by using its app. If users in the building use multiple networks simultaneously, you will need multiple GO X devices or a multi-carrier booster such as these: Small Space Signal Boosters for up to 4000 sq. ft., Medium Space Signal Boosters for up to 7000 sq. ft., Large Space Signal Boosters for up to 20,000 sq. ft., or Very Large Area Signal Boosters for up to 100,000 sq. ft.

Cel-Fi WAVE Mobile App.

The Cel-Fi WAVE app for Android and iOS devices makes it easy to optimize and monitor the GO X by allowing users to connect to the device via Bluetooth to view detailed diagnostic information, including signal quality (SINR), gain, and measures of signal strength (RSRP).

*Coverage.

The coverage area of the Cel-Fi signal amplifier kit depends on the signal strength at the location where the outdoor antenna is positioned and the number of indoor antennas it is paired with.

Outdoor Signal	Estimated coverage area
Strong (5 bars)	up to 15,000 square feet
Medium signal (3-4 bars)	up to 10,000 square feet
Weak signal (1-2 bars)	up to 5,000 square feet

 

How many antennas are required?

In general, the coverage area of a system increases with the number of antennas used. Signal does not pass through walls and air that easily, so adding antennas helps expand the coverage of a signal amplifying kit.

As a general rule, one antenna should be installed for every 750 to 1000 square feet of space in a typical office or home that is split into smaller spaces. For more open environments, including warehouses or open office floors, one antenna is needed for every 1,500 to 2,000 square feet.

Which type of exterior antennas should be used?

Yagi or the more correct term, Log Periodic Antennas are suggested for outdoor use because they are most powerful in acquiring weak signals from outside to feed to the signal amplifier indoors that boosts and then broadcasts that amplified signal through indoor antenna(e).

Outside antenna used with the Go X most often is a SureCall SC-230W Wide-band Yagi Antenna. This powerful antenna can reach cell towers at a distance of up to 30 miles and it has a gain of about 10 dB across all wireless frequencies. As it is it is directional, it needs to be installed pointing in the direction of the cell tower. Mounting equipment to attach to a 1 to 2 inch diameter pole is included. The white fiber-glass portion of the antenna should be installed above the roof line and must not be obstructed in the direction of the tower for best results.

Which type of interior antenna(s) should be used?

2 different types of internal antennae can be used with the Cel-Fi Go X: A Panel Antenna, and a Dome Antenna.

Panel Antennas.

A panel antenna has a narrow beam-width and directs signal in a specific direction.

Panel antennas can be installed on walls, which is easier in certain environments. Antenna's cable comes out at the bottom, making it possible to install without needing access to the wall's interior. A panel antenna is often the easiest to install in the first floor of a 2-story building, as putting a dome in the ceiling would be difficult. Being unidirectional, Panel antennas can also be mounted on ceiling in instances when multi-level coverage is required because it would then improve signal in the floor level below.

Dome Antennas.

Dome antennas are installed in ceilings. It is used in office buildings with ceiling tiles, or in single story buildings with access to the crawl space. The cable comes out of the back of the antenna, so access to other side of the ceiling is needed in order to install it correctly.

Dome antennas spread signal in all directions. They should be installed throughout the building to provide adequate coverage because they do not support multi-level coverage.

Cable length customization.

For most practical purposes, included cable lengths will suffice for installation. However, in rare situations longer cable(s) may be needed due to very long distance between antenna, and signal amplifier unit. Secondly, in some cases where signal that exterior antenna can capture happens to be very weak to provide enough interior improved coverage space, a customized shorter cable will be best to minimize signal loss. The reason for this is that cables incur signal loss so longer the cable, more the loss of signal incurred. Therefore, see below for optional longer or shorter custom cable purchase suggestion to facilitate installation and/or better performance.

Optional cable purchase (not required):

Kits include 30 ft. LMR400 cables to connect antennas to booster. For peak performance, always use shortest cables possible for least signal loss. Therefore, if different size cable(s) needed, buy different size LMR-400 cable(s) separately.
