CEL-FI GO G41 Complete Set – Cellular Booster with TELEVES Directional Antenna, 10 m H155 & Pro-1000-5G Indoor Antenna
This complete set based on the Nextivity CEL-FI GO G41 is a professional solution for improving cellular reception inside buildings. The system selectively amplifies LTE – and therefore automatically also 5G DSS (Dynamic Spectrum Sharing), if 5G is operated within the respective LTE band. In addition, the G41 continues to support 2G (GSM).
By combining a directional outdoor antenna, a high-quality indoor antenna and a coaxial cable extension, the cellular signal is precisely received, amplified and distributed inside the building – ideal for private homes, small commercial units and locations with weak outdoor coverage.
Set Highlights
-
CEL-FI GO G41 – LTE / 5G DSS cellular booster with 2G support
- TELEVES wideband directional antenna
-
Indoor antenna: TELEVES Pro-1000-5G (indoor/outdoor, compact design)
-
2 m low-loss cable permanently attached to the indoor antenna (SMA male)
-
+ 10 m H155 coaxial cable as extension (for flexible positioning)
- Band- & operator-selective – not a wideband repeater
- Monitoring & control via the Nextivity WAVE App
Outdoor antenna – targeted signal reception
The included TELEVES wideband directional antenna supports 2G/3G/4G/5G and allows precise alignment towards the nearest cellular base station. This provides a stable donor signal for the CEL-FI GO G41 – the essential basis for strong indoor performance.
Pro-1000-5G indoor antenna – stable indoor signal distribution
The TELEVES Pro-1000-5G is a compact wideband antenna for 4G/5G (frequency ranges up to 3800 MHz), suitable for both indoor and outdoor installation. It is used as the indoor antenna to evenly distribute the amplified signal within the coverage area. Despite its compact design, antenna gain reaches up to <8 dBi.
Cable concept – 2 m fixed + 10 m extension
The Pro-1000-5G is supplied with a 2 m low-loss cable and a pre-mounted SMA connector. For flexible placement inside the building, an additional 10 m H155 coaxial cable is included as an extension. This allows optimal positioning of the indoor antenna (e.g. centrally in a hallway or main usage area).
Coverage & Applications
Typical indoor coverage with the CEL-FI GO G41: approx. 1,000–1,250 m² (depending on building structure, frequency band, outdoor antenna and indoor antenna placement).
- Single-family and multi-family homes
- Offices & small commercial units
- Medical practices, law firms & workshops
- Buildings with GSM telephony or emergency / legacy requirements
Notes
- Supports LTE, 5G DSS and 2G, but no native 5G (SA/NSA).
- For true 5G NR (e.g. n78), we recommend the CEL-FI GO G51.
- Operation of cellular boosters generally requires approval from the respective frequency holder.
Optional remote monitoring & maintenance by Haider Telekom GmbH available (project-dependent, additional costs apply).
Haider Telekom – Why we deliberately rely on CEL-FI
As a specialist for professional cellular coverage solutions, Haider Telekom GmbH deliberately relies on channelized, band- and operator-selective systems such as CEL-FI – and consciously not on simple wideband repeaters.
| Technical aspect |
CEL-FI (Nextivity) |
Wideband repeater |
| Amplification principle |
Selective & channelized |
Unselective across entire bandwidth |
| Operator separation |
Clean, controlled processing |
Uncontrolled signal mixing |
| Network compatibility |
Very high (network-friendly) |
Dependent on environment & tuning |
| Signal quality |
Carrier-grade level |
Inconsistent |
| Long-term stability |
Very high |
Often unstable after network changes |
Our approach:
Stable networks, clean signal processing and solutions that technically come as close as possible to professional carrier systems – even if this investment is higher than with simple wideband solutions.
