Don’t be fooled by inflated power numbers dbi and dbd. Cyfre & Maximum Signal cellular amplifiers produce the maximum power allowed by Federal Law. Imitators use false test results from within their own company! Our cellular amplifiers, antennas and cables use test results provided by 100% independent testing facilities.

Maximum Signal & Cyfre amplifiers are State of the Art in every way:

  1. They require the least amount of antenna separation of any brand
  2. draw the lowest power
  3. have the most anti-oscillation features
  4. come with only professional quality components
  5. are the most powerful in their respective categories

  7. handle the most amount of devices with all devices receiving maximum power!
  8. The list goes on and on. Just check around the Internet yourself.

All of our Maximum Signal cellular amplifiers are carrier network friendly. This very important. You may think you are getting good signal with one of the other brands, but what is it doing to the signal of your friends and neighbors?
