  • Two carriers boosted simultaneously, not one
  • Redundancy if a single carrier drops out at your site
  • Two internal service antennas for coverage across two zones
  • Up to 100 dB gain per unit, the highest legally available in Australia
  • Ask us about adding Vodafone for a three network system

Description

Two carriers, one system

Every other kit in this range boosts a single carrier at a time. The Deluxe combines two G41 repeaters into one installation so Telstra and Optus are both boosted simultaneously, feeding two internal service antennas.

Choose it when:

  • Your staff, contractors and visitors are on different networks and one carrier is not enough
  • Losing a single carrier at your site is not acceptable, and you need redundancy
  • You are covering a workplace where communications are business critical

Need Vodafone as well, or a three network system? Talk to us about a combined solution or a full distributed antenna system. Call 0439 439 611.

Why the Cel-Fi GO G41?

Highest legal gain in Australia. Up to 100 dB of system gain per unit with +20 dBm output per channel, driven by Nextivity's fourth generation IntelliBoost chipset. Significantly more headroom than the previous GO 31 and GO 32 generation.

Two bands at once, per repeater. Each G41 relays two frequency bands simultaneously, so a low band can carry voice and reach further through walls while a higher band carries data. Across two units that is four bands working for you.

Network safe by design. Cel-Fi units are self-optimising. They continuously measure the donor signal and adjust their own gain to avoid interfering with the network. That is why carriers approve them and why they carry a no-noise guarantee.

Matched antennas and low-loss cable. Every kit we supply pairs the repeaters with high quality antennas and low-loss cabling selected for Australian network bands. Poorly matched antennas and cheap cable are the most common reason a booster underperforms, and the easiest place for a supplier to cut cost. We do not.

Professional installation recommended. A dual repeater system needs careful donor antenna placement to keep the two units from interfering with each other. Our team designs and installs cellular coverage systems across Sydney and NSW.

Will this work at my address?

A booster amplifies existing signal. It does not create it. The G41 needs a usable mobile signal somewhere on the outside of your building, most often at roof height, to capture and rebroadcast indoors.

This is very likely the right solution if

  • You get one or two bars outside but nothing usable inside
  • Calls drop when you walk indoors, or you have to stand near a window to hold one
  • Your building has foil-backed insulation, double glazing, concrete or Colorbond, all of which block mobile signal effectively
  • You are in a suburban, semi-rural or fringe area where outdoor coverage is workable but indoor coverage is not
  • You are covering a home, home office, shop, shed or small commercial suite

A booster is not the answer if

  • You have no usable signal anywhere on the property, including at roof height. A booster cannot help and we will tell you so.
  • You need coverage across a large or multi-storey commercial site. Look at the G51 or ask us about a designed system.
  • You want to boost signal in a moving vehicle. You need the R41 ROAM instead.

The platform can be architected to cover up to 3,000 m² with multiple internal antennas and a designed distribution system. A kit with one internal antenna will not achieve that. Real coverage depends on donor signal, building materials and antenna placement. Call 1300 398 221 if you're unsure.

Compliance

Legal to own and use in Australia

Most mobile phone boosters sold online cannot legally be operated here. This is the part buyers most often get wrong, and it carries real consequences.

Generic boosters sold online

  • Illegal to operate, own or supply in Australia
  • Not type approved by ACMA
  • Interfere with carrier networks and degrade service for others
  • Carriers can and do locate them
  • Substantial penalties apply to the operator

Cel-Fi by Nextivity

  • Holds an ACMA exemption for legal use in Australia
  • Authorised by Telstra, Optus and Vodafone
  • Self-optimising, with a no-noise guarantee to the network
  • The only repeater range legally available here
  • Supplied and supported by an accredited Australian dealer

Indoor coverage with one, two and four internal antennas

How do I install it?

Coverage scales with the number of internal antennas and how well the donor antenna is aimed. Both matter more than the repeater itself.

Easy Self Installation

Mount the donor antenna high and clear, ideally on a roof mast aimed at the tower, run the supplied low-loss cable, and place the internal antenna with enough separation from the donor to prevent feedback. Many of our customers do this themselves and get a good result.

G41 vs G51: Which coverage solution is right for you?

Choose the G41 for broader compatibility and dependable everyday performance. Choose the G51 if you specifically want true 5G on 3500MHz (n78) and you are in an area where that signal is available.

5G Focused

Cel-Fi GO G51

Best for customers who specifically want mid-band 5G performance.

  • Supports true 5G NR on 3500MHz / n78
  • Designed to bring mid-band 5G indoors
  • Dual-band relay support
  • Typically pairs 5G 3500MHz with a 3G/4G band for broader connectivity
  • !Best results depend on having usable 3500MHz 5G in your area
  • !Usually better suited to metro and stronger 5G locations

Best for

Customers in strong 3500MHz 5G areas who want the highest possible 5G-focused performance.

Choose G41 if:

  • You want the safer all-round option
  • You need dependable everyday coverage
  • You are not specifically targeting 3500MHz 5G

Choose G51 if:

  • You want true 5G on 3500MHz
  • You are in a strong metro 5G area
  • You want a more 5G-focused solution
