Precision over Scatter: Your High-Range Helium Antenna
Why waste your transmission power in all directions when your target is clearly defined? The Interline PANEL 8 HELIUM SL is a highly specialized LoRaWAN Panel Antenna that operates on the spotlight principle. Instead of a wide 360° scatter, it bundles the 8 dBi power into a precise 70° horizontal and 60° vertical sector. The result: a drastically increased signal strength and range exactly where you need it. Ideal for connecting distant sensors, covering a specific neighborhood, or maximizing performance over open areas. This type of directional Antenna is the key to efficient Network construction.
Built for Tough Outdoor Use
Once mounted, an antenna should perform its duty reliably for years. The PANEL 8 HELIUM SL was developed for exactly this purpose. The housing is not only UV-resistant but also offers reliable protection against splashing water from all directions with its IP64 protection class. It withstands wind speeds of up to 160 km/h and operates in an extreme temperature range from -40°C to +80°C. The integrated DC grounding also safely dissipates static charges, protecting the sensitive input of your Helium Miner or gateway.
Flexible Mounting and Easy Alignment
The best directional antenna is useless if it cannot be precisely aligned. That's why the Interline antenna comes with a robust and flexible mast mount. This allows you to both tilt and swivel the antenna to perfectly hit the signal sweet spot. The mount is designed for masts with a diameter of 38 to 51 mm. Thanks to the N-female connector, you can use high-quality, low-loss coaxial cables for an optimal connection.

Frequently Asked Questions (FAQ)
For which applications is this antenna ideal?
This antenna is perfect for LoRaWAN and Helium applications where targeted coverage is required. Typical scenarios include connecting sensors in a specific sector, supplying urban fringe areas from an elevated point, or installations on coasts and in front of hills where back radiation is undesirable.
What does 'directional antenna' mean compared to an 'omni-directional antenna'?
An omni-directional antenna sends and receives signals evenly in all horizontal directions (360°), similar to a light bulb. A directional antenna like this one focuses the energy in a specific direction, similar to a spotlight. This increases the range and signal quality in that direction but does not cover other areas.
Is the antenna suitable for operation with a Helium miner?
Yes, the antenna is specially optimized for the EU868 frequency band and is excellently suited for use with Helium miners in Europe to improve coverage in a specific direction and potentially increase HNT earnings.
What does DC grounding mean and why is it important?
DC grounding (Direct Current grounding) means there is a direct electrical path from the antenna element to the mounting bracket. This allows static charges, which can be generated by wind or friction, to be safely discharged to the grounded mast system. This protects the sensitive input of the connected miner or gateway from damage.
Does the antenna need to be mounted exactly vertically or horizontally?
Yes, for classic H/V polarization, the antenna must be precisely aligned either horizontally or vertically, depending on which polarization plane is optimal for the target Network. The included bracket supports this precise adjustment.
What cable do I need to connect the antenna?
The antenna has an N-female connector. You will need a high-quality, low-loss coaxial cable (e.g., LMR-400 or equivalent) with an N-male connector on one end and the appropriate connector for your gateway or miner (often RP-SMA or SMA) on the other. The cable length should be kept as short as possible to minimize signal loss.
