Product Description
This is a high quality outdoor antenna designed to be deployed outdoor, for better range. The antenna connector is one with the antenna body, because this design increases the resistance of the antenna to external conditions further. It is IP67 rated, making it weather proof. It is designed to work in the sub-GHz bands like US915, AU915, AS923.
The coverage that this antenna provides makes it ideal for deployment outdoors in a high altitude spot within the outskirts of an urban area, where there is a relatively low number of other buildings and people in general. In such a scenario it is likely that the signal will be able to cover a longer distance until it reaches the intended recipient of the transmission. If you need the transmission signal to reach the center of the urban area or a nearby located village or town, it is likely that this antenna will provide you with the needed coverage.
As this is a mid range dBi antenna, it is designed to provide better, fuller and more stable coverage for devices that are situated nearby, but not too close to it, as opposed to an ever higher dBi antenna, which would be able to do the same for devices that are situated even further away from its location. The general logic related to the difference between a higher dBi antenna and a lower dBi antenna is best understood by viewing the picture below:
The exact shape of coverage for antennas in general resembles that of a doughnut, while the exact radiation pattern for the currently discussed 5 dBi antenna can be viewed on the picture below.
Overall the specs of this particular antenna are a great fit for use with a Helium hotspot, such as the RAK Hotspot V2, or MNTD Hotspot mostly because you will be able to reach a great number of witnesses in areas that are near, but not too close to where the deployment would be situated, especially if you manage to install it high and close to the top of a building, where it would have a direct line of sight towards the far placed, but still visible buildings.
An example for a good deployment of such an antenna in relation to other Helium hotspots nearby can be seen on the image below.
You should also keep in mind that it is always a good idea to use a combination of antennas with varying dBi in order to achieve better overall coverage and fewer blind spots.
To choose the appropriate antenna with regards to the LoRa frequency of your region, please refer to the TTN's guide, and/or the Regional Parameters Documentation provided by the LoRa Alliance.
Note: This antenna is designed to be directly mounted on the enclosure of the Gateway. It is suitable for RAK7240 and RAK7249. The antenna is compatible with Outdoor Enclosure for RAK Hotspot V2, Bobcat Outdoor Enclosure Kit, and Antenna Magnetic Base.
