Is this the right antenna for me?

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 these are important to you we would encourage you to look at the following two antennas:
How does this Yagi cover both bands?
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 was able to be widened to the full 698-890MHz required to operate on both bands. This clever design is a credit to RFI's brilliant engineers.

What connection does this antenna have?

This antenna has an N Female connector for attaching your required length of cable. You can use the dropdown box below to select how much cable you would like to purchase. You'll notice all cables in the dropdown box end with a FME connector - this is the connector used to attach your patch lead or mobile phone cradle. If you need something else or a different length, please use the Cables menu.
