📐 Installation is Key (For Crystal-Clear Signal)
To replicate the clean signal you hear on the Twente SDR, you need to pay attention to placement:
| Positioning Requirement | Objective |
| Distance: Away from metallic objects or walls. | Minimize capacitive coupling and household noise. |
| Minimum Height: At least 4 meters from the ground / support surface. | Eliminate most local RFI noise. |
| Maximum Efficiency: Recommended height of 15 meters. | Capture the pure electric field for the best DX performance. |
IMPORTANT WARNING: Electric Field Antenna
ATTENTION HAM! The Mini-Whip, as an electric field antenna, is incredibly sensitive. If installed near strong local RFI sources (e.g., broadcast transmitters or industrial interference), the internal amplifier can saturate (overload), introducing intermodulation.
High installation and distance from noise are crucial to make the most of its low-noise design and enjoy world-class SDR reception!
Don't wait! Add the world's most famous SDR antenna to your station now!
