RFI Next-G+4GX 15dBi Yagi Antenna - 700-890MHz


Key Features


  • Covers both Telstra Next-G and 4GX

  • Fully welded construction for maximum performance and reliability

  • Narrow beamwidth & high front to back ratios effective in reducing interference

  • Can be configured in stacks or bays for higher gain applications

  • Short low loss cable tail with N-female connector

  • Australian manufactured and warrantied.




  • 15dBi Yagi are ideal antennas for a diverse range of environments

  • The 700-850MHz RFI 15dBi Yagi is suitable for rural customers seeking a low cost method of connecting to the new Telstra 4GX 700MHz network at a long range, without going to the cost of installing a large panel antenna

  • This antenna also has fantastic performance on the Telstra Next-G network, and is a good choice for pairing with the Telstra Smart Repeater Pro

  • It's important to note that 4G speeds will be slower through this antenna than using a MIMO antenna (approximately half the speed of a MIMO connection)


This antenna will not permit Carrier Aggregation - if this is important to you, we would encourage you to look at the following two antennas:



Additional Information


  • Yagi covers both Telstra Next-G (850MHz), and Telstra 4GX (700MHz)

  • We set RFI the challenge of designing us a high gain antenna to cover both Telstra Next-G (850MHz), and Telstra 4GX (700MHz)

  • Naturally, Yagi antennas can only be tuned for one particular band (i.e. either 700 or 850MHz), however by compromising on VSWR and accepting a lower electrical efficiency, the antenna bandwidth is widened to the full 698-890MHz required to operate on both bands

  • This clever design is a credit to RFI's brilliant engineers.
