Cel-Fi GO G41 Smart Signal Repeater – Home & Office Kit

(Premium RFI Equipment)

The Cel-Fi GO G41 is a fully ACMA-approved, carrier-endorsed smart signal repeater built specifically to improve mobile coverage inside homes, small buildings, and office environments. It is the ideal choice for properties that have good 4G outdoor signal but struggle with weak indoor coverage or poor 5G mid-band penetration; a common issue in suburban, semi-rural, and modern insulated buildings.

Supporting 4G and 5G capability across Telstra, Optus, and Vodafone, the G41 is designed to bring consistent voice and data performance to everyday spaces without the complexity or heavy infrastructure requirements of commercial systems.

Every G41 kit we supply includes premium RFI external antennas, internal distribution antennas, and ultra-low-loss RFI cabling. These Australian-engineered components ensure exceptional signal capture outdoors and cleaner, more efficient signal delivery indoors leading to noticeably stronger mobile coverage throughout your home or office.

With increased output power, the G41 is capable of being extended to support approx. 3,000 m² of indoor coverage with the correct architecture; double that of the previous GO 31/32 generation, and supports two simultaneous channel bands to improve call reliability and data speeds.

Best For: Homes, Offices & Smaller-Scale Spaces

The Cel-Fi G41 is the recommended model when:

  • You have strong or usable 4G outside, but poor indoor coverage
  • Your home or office struggles with 5G mid-band penetrating the building
  • You are boosting single dwellings, small offices, shops, studios or small-medium floorspace
  • You want a reliable, legal, ACMA-approved repeater for everyday use

This makes the G41 ideal for:

  • Houses & townhouses
  • Home offices & remote work setups
  • Small business offices & retail spaces
  • Granny flats, garages, sheds & outbuildings
  • Smaller commercial suites or single-storey buildings

If you have outdoor mobile signal—especially 4G—the G41 paired with RFI antennas can deliver strong, stable indoor coverage.
