Precision over Dispersion: Your 8dBi LoRaWAN Directional Antenna
No more wasted signal! While an omnidirectional Antenna distributes its energy in all directions, the Interline PANEL 8 HELIUM SL concentrates its full 8 dBi gain precisely into one sector. This is ideal for stabilizing connections to distant sensors or maximizing coverage in a specific district or valley. If you know exactly where your IoT devices are, this panel Antenna with slant polarization for NLOS is the technically superior choice among LoRa / Helium Antennas to increase the range of your Helium Miner in one direction.
Superior NLOS Performance thanks to Slant Polarization
In cities or built-up areas, a direct line-of-sight is rare. Signals are reflected by buildings and change their polarization. This is exactly where slant polarization (±45°) shows its strength. It can receive these 'rotated' signals much better than a purely vertically polarized antenna. The result for you: a more stable connection, a better signal-to-noise ratio (SNR), and significantly fewer lost data packets. This makes it a top choice among specialized Antennas.
Built for Eternity: IP67 Protection for All Weather
This antenna is designed for uncompromising outdoor use. The UV-resistant housing with IP67 certification is absolutely dustproof and can even withstand temporary submersion unharmed. Whether it's biting cold at -40°C, extreme summer heat at +80°C, or storms with up to 160 km/h – the Interline PANEL 8 HELIUM SL operates reliably and ensures the operation of your Network under the harshest conditions. Consider our Antenna Mounting Accessories for secure installation.

Frequently Asked Questions (FAQ)
What is the main advantage of 'Slant' polarization in this antenna?
Slant polarization improves reception in Non-Line-of-Sight (NLOS) environments, such as cities. It can more effectively receive radio signals that bounce off buildings and change their polarization, leading to more stable connections and less data loss. This is particularly useful for LoRa / Helium Antennas.
Is the Interline PANEL 8 HELIUM SL suitable for every Helium Miner?
Yes, thanks to its standardized N-female connector and 50-ohm impedance, it is compatible with virtually all Helium Miners and LoRaWAN gateways that have an external antenna connection of this type. Only a suitable, short, and low-loss Antenna Cable is required.
Do I need to ground this antenna?
Yes, grounding is strongly recommended for safe operation. The antenna features DC grounding, which dissipates electrostatic charges. The mast on which the antenna is mounted should be professionally integrated into the building's Lightning Protection system to protect connected devices.
Can I also use this antenna indoors?
Although it is designed and certified for outdoor use (IP67), indoor use (e.g., in an attic) is technically possible. However, walls and ceilings severely restrict signal propagation, which is why free outdoor mounting is always recommended for optimal performance with this LoRa / Helium Antenna.
What does the beamwidth of 70° x 60° mean in practice?
This describes the main cone of signal radiation. At a distance of 1 km, the antenna would primarily 'illuminate' an area of approximately 1225 meters in width (70°) and approximately 1050 meters in height (60°). Devices outside this cone will receive a significantly weaker signal from the LoRa / Helium Antennas.
How does this Panel Antenna differ from a Yagi Antenna with the same gain?
A Panel Antenna like this typically has a wider beamwidth (here 70°x60°) and is more compact and discreet. A Yagi Antenna focuses the signal even more strongly (narrower beamwidth) and is therefore better suited for extremely long point-to-point connections, while the Panel Antenna is ideal for covering an entire sector or a district.
