Installation Suggestion The antenna is recommended to installed in a relatively open and high position, such as the roof, near the window or out of the window. If the antenna is placed indoors, the signal transmission distance will be reduced. | Higer dBi is not always better - l Choose a lower dBi antenna if you’re in the city or surrounded by the tall buildings(A high hotspot density).
- l Choose a higher dBi antenna if you living in the suburbs or wide open spaces(A low hotspot density).
| Low VSWR The VSWR of this antenna is 1.12. Specifically tuned for the US 915MHz frequencies. Because anything below an SWR of 1.5 has a minimal (4% at 1.5) impact on range,the closer the VWSR is to 1, the smaller the reflection. |
