Do you work with wAP LR2 or similar sets? To get additional network coverage (up to 3-4 km in line of sight), we suggest adding an external 8dBi omnidirectional antenna - TOF-2400-8V-4. This antenna can be used with any 2.4 GHz device if needed. It not only works with 2.4 GHz LoRa® connectivity, but also supports regular 2.4 GHz WLAN.It comes with a 1m SMA cable and a mechanical bracket for quick and easy mast mounting - when you need extra network coverage. Compact size and increased strength without sacrificing power - this antenna will get the job done.
