1 x DC Cigarette Lighter CLA power lead. Can be Hard Wired. (290N035-003)

Important Info:

Our standard Cel-Fi Mobile Booster kits all come with the following 3 components:

  • Cel-Fi GO G31 Repeater which can be ordered as a Telstra, Optus or Vodafone repeater booster.
  • 12V power cable with Cigarette Lighter Adaptor (CLA). The cigarette lighter adaptor can be cut off and the unit can be hard wired by an auto electrician.
  • RFI T7 In-Car flat rectangular black server antenna.

Then you need to select the external donor antenna that will suit your requirements and there are 3 important factors to consider when selecting the CORRECT antenna which are in order of importance:

  1. Gain
  2. Strength and Durability
  3. Removeable Whip

Options for Donor Antenna Gain:

GainSuitable for
5dBiAround and close-ish to town or where the cellular towers are located in built up or hilly areas. Perfect for in the bush not that far out of town where signal is scratchy. Shorter distance but better in hilly/bushy terrain.
6.5dBiThis is an all round antenna suitable for a fair bit further out of town but slightly flatter terrain. This is the antenna gain that we (Tin Can Solutions Owners) use and recommend which we have been able to achieve an extra 50km useable Telstra service compared to another phone on Telstra not connected to the Cel-Fi. We have been able to run our business remotely by taking phone calls and process orders in places that we normally would't be able to without this setup.
7.5dBiSuitable for very flat/undulating terrain where longer distances are required but there's no mountains around blocking the signal. Perfect for people who live and work in these locations or for people who are going to travel in these areas.


The donor whip antennas that we supply come in 3 versions of strength and durability.

  • Standard Duty - RFI CD Series Antennas - Perfect for highway use and mild dirt roads, comes with a standard duty spring base. These are a fixed whip antenna and cannot be removed.
  • Medium Duty - RFI CDR Series Antennas - Better suited to highway use with dirt roads thrown in and come with a medium duty spring base and removeable whip which unscrews off the base.
  • Heavy Duty - RFI CDQ Series Antennas - Perfect for severly corrugated dirt roads and 4WDing/Off-roading. These are really tough antennas which look the part and come with a heavy duty spring base and a RFI Quickfit removeable whip which unscrews off the base.

We also stock a magnetic base antenna for applications where you want to take the unit between vehicles. The magnetic base cellular LTE antenna is only recommended for highway/sealed roads use where the signal is scratchy such as 1 bar of service that you need to get that little bit of extra service but don't want to mount an antenna to your vehicle. The antenna gain is only 2.5dBi to 4dBi so it is suited to shorter distances where service intermittently breaks up between mobile phone towers.

So which Antenna do you get?

There is a very informative and totally independent review/article on testing of some well known brands of Cel-Fi Go compatible antennas and which ones performed the best. This link is to an external website called "CHOICE" and we have absolutely no affilliation with the author or the website. click here for the article which we think is a worthy read.

This article clearly shows that the RFI antennas outperform other brands by over 10km and this is the exact reason why we believe in RFI Antennas and we are an authorised RFI dealer in Capalaba Brisbane and a Capalaba QLD stockist of RFI antennas.

RFI antennas are simply the best available on the market.

Ease of installation:

Our CelFi kits are all plug and play which means you can just plug it all together without the need to order more parts and adaptors to join things together.
