Will it work the same as new?

Open box used Cel-Fi GOX by Nextivity should work perfectly well just like the brand new version cellular amplifier.

It is designed to work with one carrier network at a time. Therefore, it is switchable to whichever carrier network service you need to boost).

What exactly does "Open Box" mean?

Consumer Reports states, "Typically, open-box items are goods returned by customers, inspected by the retailer, found to be in working order, and re-sold at a discount, rather than returned to the manufacturer".

Questions & Answers

QUESTIONS & ANSWERS

Ask a Question
  • Looking to purchase the used Cel-Fi GO X that you have for sale on the Signalbooster.com website. I had a few of questions: 1. Would you be willing to offer selling the unit with a higher-gain outdoor antenna? Looking to use the RF Boost Long Range Antenna For Cellular & Wi-Fi (Grid Parabolic). 2. Is the RF Boost Grid Parabolic Antenna the same as The Long Ranger from Cel-Fi? 3. I will be putting up the antenna in an area where signal strength for Verizon service is between -110 and -120. I can hold calls, but data service is not good. The antennas in the area do serve LTE coverage. 4. The area is heavily wooded around the property. Would the Grid Parabolic have a significant advantage to using the high-gain Yagi included with this listing? 5. Is there a difference between the dome antenna and a panel antenna for usage within a 100 foot area? 6. Will I have any problems placing the Grid Parabolic and Panel/Dome antenna within 25 feet of each other?

    Thanks for your questions, here are answers:

    Question 1. Would you be willing to offer selling the unit with a higher-gain outdoor antenna? Looking to use the RF Boost Long Range Antenna For Cellular & Wi-Fi (Grid Parabolic). 

    Answer: Sorry, the Cel-Fi kit comes with Cel-Fi branded Yagi antenna but we can offer 10% off on RF Boost antenna purchase with discount coupon code 10BFCM for a limited time.

    Question 2. Is the RF Boost Grid Parabolic Antenna the same as The Long Ranger from Cel-Fi? 

    Answer: The RF Boost Parabolic Grid antenna offers higher gain up to 26dBi than Cel-Fi Long Ranger antenna which offers up to 14dBi Gain. See preceding link and please confirm is that the antenna you're referring to?

    Question 3. I will be putting up the antenna in an area where signal strength for Verizon service is between -110 and -120. I can hold calls, but data service is not good. The antennas in the area do serve LTE coverage.

    Answer: This solution should work for your needs.

    Question 4. The area is heavily wooded around the property. Would the Grid Parabolic have a significant advantage to using the high-gain Yagi included with this listing? 

    Answer: Yes it will have significant advantage, but know that it is ultra directional antenna and will need to be precisely pointed to nearest cell tower with no margin of error. Recommend using Signal Meter to help with directing antenna to Verizon cell tower.

    Question 5. Is there a difference between the dome antenna and a panel antenna for usage within a 100 foot area? 

    Answer: Not much, the omnidirectional Dome antenna mounted on ceiling should cover that conical diameter base. Directional Panel antenna does offer slightly higher Gain but it would only be helpful if coverage needed is in a rectangular space or hallway whereby you can mount Panel antenna on wall facing the longer length of space that needs covered. A panel antenna can also be mounted on ceiling if coverage is needed below the floor on lower level of the house right underneath.

    Question 6. Will I have any problems placing the Grid Parabolic and Panel/Dome antenna within 25 feet of each other? 

    Answer: No, because directional antenna pointed away from Panel/Dome antenna should not cause interference / oscillation / feedback with that much distance in between plus other standard building composite materials that will exist to dampen feedback.

  • Can a single unit be reconfigured for a different cellular carrier if I change cellular carriers? If not, can it be traded in for the correct unit? At what cost? What is a changeable multiple cellular carrier network booster kit? What does that kit cost?

    Yes, the carrier can now be changed on any Cel-Fi Go X kit simply and easily in a jiffy using the free Cel-Fi app you can download on your smartphone from Google's Play Store or Apple's App Store. Therefore, no costs applicable since no trade-in is ever needed:)

Warning

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
