9dBi Magnetic Base Omnidirectional Antenna


Key Features


  • Supplied with 3m of LMR-195 cable

  • Good performance on all cellular networks

  • Comes in three easily assembled sections - perfect for FIFO.




  • This type of antenna is popular for those struggling to receive signal indoors despite ample signal outside the house, or low signal in remote and rural areas

  • This high performance magnetic-mount antenna demonstrates exceptional wideband performance on the lower band 3G networks such as Telstra Next-G and Optus 3G, but provides 6dBi gain on the 4G networks

  • Widely used across many of the Queensland and WA mine sites, this Telstra Next-G antenna is a popular choice - used to solve weak phone reception inside temporary site buildings and portable accommodation dongas.

  • Ask us about our mining packages - if you've got a phone or Internet issue when travelling or while onsite, there's a good chance we've already got the solution you'll need

  • Ideal for increasing the strength, speed, and reliability of your mobile phone or wireless broadband device. This impressive antenna stands at 81cm tall making it small enough to use indoors but big enough to pack a punch. The magnetic base easily mounts onto any flat metal surface for maximum performance

  • If your mobile phone reception or wireless broadband internet speed is very low, and a small antenna just won't cut it, this antenna can be an effective way to give your signal a big kick in the right direction

  • The true beauty of this antenna lies in its versatility; it performs well indoors, on the car, mounted on machinery or on the roof -  for these reasons the 9dBi magnetic base antenna is one of our top sellers!


Why does it need a metal surface?


  • A metal surface such as a filing cabinet, car roof or gutter acts as a 'ground plane' for the antenna, which acts as the 'second half' of the antenna, vastly increasing performance

  • The larger the metal surface, the better the performance

  • If you don't have a metal surface to mount the antenna, you can use the antenna on any surface at a decreased level of performance (we generally find it to be twice as powerful when mounted on metal).
