Industry&com 12dbi 868mhz915mhz optimised tuned for helium for omni fiberglass aerial antenna

Features: * brand new and high quality * made of high quality materials, solid and practical * the antenna has an n sma connection line, so it can be easily connected to the for gateway and all other for helium miners.

* this antenna can be used in any environment where long-distance for lora connection is required, for agriculture, environmental monitoring and urban * low standing wave ratio: * 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 antenna matching) * how to choose dbi? * lower dbi: excellent performance on uneven terrain or areas with high hotspot density.

* higher dbi: excellent performance on flat terrain and low hotspot density.

* medium dbi: very suitable for environments between the other environments mentioned above.

* what is the rated gain and maximum gain? * the rated gain refers to the stable value that the antenna can achieve under normal conditions, and the maximum gain refers to the maximum value that can be achieved under minimum loss and optimal environment.

but this value is not a fixed value, and the gain often fluctuates.
