Questions & Answers


Ask a Question
  • I'm looking at purchasing your Cel-Fi Go+ product for my houseboat, but I would like to extend the server antenna coverage to cover a few boats. Can I purchase a 3 Way Splitter (Wide Full Band 50 Ohm Part SC-WS-3 By SureCall) to add a couple more dome antennas? And if so, what is the max cable length for each run?

    Your request can possibly work, but it depends on amount of area you're trying to cover along with the strength of incoming signal.

    Cable lengths are typically around 30 to 50 feet. Please contact us as we can provide kits and design systems for your application.

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 of your home / building. Please check outside signal level in decibels before ordering. 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.

If it is too weak, 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.
