Do I need an Antenna, or a Booster, or a Modem / Router?

If you are looking to improve your cellular 3G or 4G signal strength for Voice Calls, SMS and Data this can be achieved in two ways:

  • Connect an external antenna to your 3G or 4G device. Your device MUST have a facility to connect a cable to it. Our antenna cables are terminated with an SMA plug, so if your device has a different type of connector you will need a cable adapter.
  • Use a “Booster”, keeping in mind that the ONLY legal boosters able to be used in Australia are the Cel-Fi brand by Nextivity. Your Cel-Fi Booster is connected via the supplied cable to an external antenna, plugged in to a convenient 240v mains power point / or 12V / 24V DC source. The Cel-Fi is then connected to the supplied internal antenna inside your premises which broadcasts the 3G or 4G signal throughout your premises.

This means that any device within range of the internal antenna will see a MUCH stronger signal, very often 5 bars throughout, depending on the size of the building and construction. Your devices, ie. phones, tablets, modems or routers will benefit from this increased signal, no cabling required.

If you are looking to improve your 3G / 4G cellular data connection only:

  • You can use the Booster scenario described above if you have a 3G  /4G cellular modem / router with its own attached, or built in 3G / 4G Cellular antenna.
  • Use a 3G / 4G cellular modem / router and attach an externally mounted antenna connected by cable. Please note our antennas come with a cable terminated with an SMA connector. If your device uses a different type of connector you will need an adapter.

Often a dedicated 3G / 4G modem / router with externally mounted antenna(s) will provide better data throughput than the Booster scenario, if provisioned with 2 antenna sockets, and fed with a MIMO antenna. The router will then supply wifi, or cabled network connection for your data only devices.

Please Note: Purchasing only an external antenna to improve mobile phone signals will NOT improve your reception unless your phone has the capability to accept a cabled connection.
