High Gain 8dBi Waterproof Fiberglass Antenna for LoRa IoT Gateway - 915MHz Long Range with 3M/10FT Cable - Compatible with Helium Hotspot, RAK, Nebra, Bobcat 300, SenseCAP M1, SyncroB.it, Finestra HNT Miner - Perfect for Outdoor Mining & Remote IoT Connectivity

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 1.04,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. Read more How to Choose the Best Outdoor Antenna ● Take a look at the images and notice the different coverage for antennas. ● A dBi higher antenna doesn't necessarily mean wider coverage or more HNT earnings. ● The higher dBi antenna is, more narrow and further its signal coverage gets. ● Please select an appropriate gain antenna according to the display distribution of the helium detector. ● Choose a lower dBi antenna if you’re in the city or surrounded by the tall buildings(A high hotspot density). ● Choose a higher dBi antenna if you living in the suburbs or wide open spaces(A low hotspot density). Antenna Installation Tips Don't connect and disconnect antennas without powering down the miner. Avoid putting the Antenna in locations where signal strength can be heavily degraded; Position away from:Lighting fixtures & motors、Low-E or coated windows、Large vertical metal or concrete objects. 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. For outdoor use, recommend to install the lightning arrestor (Package do not include lightning arrestor) Signal transmission is affected by many factors, including distance, the density of high-rise buildings, view openness; Please try more antenna installation locations to find a better spot. Choose a low-loss extension cable (50 ohms), and it is not recommended to use too long extention cable. Read more

Installation reminder: If it is used outdoors, we recommend that you install it in an open place, please keep it as vertical as possible, install the antenna at the highest place outdoors to get a better signal. if it is used indoors, we recommend placing this inside near a window.

Note: the longer the cable, the greater the gain loss for the antenna, If you need a longer cable, We recommend buying MORE THICKER LOW LOSS cable and suitable length of cable (must be 50ohm) , If want to get more witnesses.
