So given their suggested Marine Solution kit, cell towers donate connectivity to the Cel-Fi Marine antenna, which is then boosted and served to the boat’s phone(s) with Cel-Fi’s patch antenna. What I call outside and inside cell booster system antennas, Cel-Fi calls donor and server, which makes sense when you consider situations beyond boats and RVs. The same device can be easily switched to mobile mode with built-in software switching to deliver 65 dB gain - which is up to 100 times greater than other solutions on the market - for vehicles and boats on the move. Consider the signal gain claims:Ĭel-Fi GO+ offers industry-leading 100 dB gain in stationary mode - 1000 times greater than other offerings - to provide the highest carrier grade performance available. The Cel-Fi developers have apparently been meeting the FCC’s special single-carrier high-power standard for years - primarily for high-performance fixed-location boosters - but they only launched the more flexible dual-mode GO+ last summer. More specifically, the Cel-Fi GO is a carrier-specific booster able to add 65 dB of gain in mobile mode or 100 dB in stationary mode, regulatory modes which might also be described as boat underway or at anchor. So, although this first testing was only done in my shop with an already usable Verizon signal, I’m quite hopeful that the GO will get the job done in even the more challenging cell holes found cruising the coast of Maine (and elsewhere).

The well-made hardware also supports a Bluetooth app that delivers significantly more information about what the booster is doing, as well as several control options. The Cel-Fi GO is different from every other cell booster I’ve tried over the years, starting with significantly greater signal amplification (when needed).
