Introducing the CEL-FI GO ROAM R41: A plug-and-play cellular coverage solution, tailor-made for nomadic applications. Helping keep you connected while on the move, it's the ultimate companion for your travels. 

Network Selection: Telstra, Optus, Vodafone 

R41 CEL-FI GO Features:

  • Versatile in its application, the CEL-FI GO R41 is ideal for enhancing mobile signal reception in a diverse array of vehicles, including cars, vans, 4WDs, trucks, motorhomes, caravans, and boats.
  • Supporting 5G NR Low Band, 4G, and 3G technologies, the device ensures compatibility across Telstra, Optus, and Vodafone Networks.
  • Positioned as a viable successor to the GO G31/G32 Mobile systems, the R41 boasts extensive frequency support, spanning from 700L/850/900/1800/2100/2600 to Band 20 & 26.
  • Offering comprehensive coverage, the R41 caters to a large frequency spectrum pertinent to the Australian market, ranging from 698 MHz to 2700 MHz. Notably, the RFI CD/CDR/CDQ819x series stands out as one of the few antennas capable of supporting this broad frequency range.
  • The incorporation of the latest 4th generation Nextivity proprietary IntelliBoost chip ensures precise coverage tailored to the specific signals of mobile network operators.
  • Streamlined installation is facilitated by the plug-and-play operation, enabling swift deployment without intricate setup procedures.

Automatic Band Selection 

The intuitive design of the R41 CEL-FI GO streamlines operation, eliminating the need for manual band selection. Employing advanced techniques, it dynamically selects the optimal signal band, ensuring seamless voice and data transmission tailored to the prevailing network conditions.

Our Recommendation on External Antennas is the RFI Variants with the CDQ8195B being the most popular. Using cheaper & lower quality antennas will have dramatic effect on performance of the ROAM R41. Please note: Input Voltage: 12VDC.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
