Working with the wAP LR2 kit or similar setups? For extra network coverage (up to 3-4km in the line of sight), we suggest adding an external 8 dBi Omni antenna - the TOF-2400-8V-4.If necessary, this antenna can be used for any 2.4 GHz device. Not only it works with the 2.4 GHz LoRa® connectivity, it also supports the regular 2.4 GHz WLAN. It comes with a 1m long SMA cable and a mechanical holder for quick and easy mast attachment – when you need that extra network coverage. Compact size and increased durability without sacrificing the power – this antenna will get the job done.
