Feature:

1.The antenna 55cm, LORA antenna outdoor omnidirectional fiberglass antenna LTE outdoor long-distance receiving antenna

The antenna has an N SMA connector cable, so it can be easily connected to the gateway and all other helium miners.

2.The antenna can be used in any environment that requires a long-distance LoRa connection, for agriculture, environmental monitoring, and urban monitoring

3. With two fixing clips, it can be more convenient to move the antenna installation

Low VSWR：

The VSWR of this antenna is 1.1, which is lower than other similar antennas (the closer the VWSR is to 1, the smaller the reflection and the better the match of the antenna )

How to choose dBi？

Lower dBI: Great performance on uneven terrains, or areas with a high hotspot density.

Higher dBI: Great performance on flat terrain and low hotspot density.

Middle dBI: Perfect for those eniorments that fall in between the other enviorments described above.

What is Rated gain and maximum gain?

Rated gain refers to the stable value that the antenna can achieve under normal circumstances, and the maximum gain refers to the maximum value that can be achieved under the lowest loss and the best environment, but this value is not a fixed value, and the gain is often fluctuating.
