NTi MegaDipol DX HF Active Dipol
The MegaDipol 300DX is a broadband active dipole with a maximum upper working frequency of 300 MHz. The dipole reacts to the electrical component (E-Field) of the electromagnetic field and will deliver best results regarding signal strength and SNR (signal -to-noise-ratio) at locations with little or no locally generated interference.
In contrast to simple E-field antennas with only one radiating element, the symmetrical construction of the MegaDipol 300DX, will result in almost no negative resonance effects or reflections caused by the coaxial cable.
Particularly in electrically quiet environments, it can really play to its strength in efficiently amplifying weak signals. In practical operations, a maximum signal-to-noise ratio of 110dB was achieved!
Key Facts
- Ultra-wideband design from 9kHz - 300 MHz
- Compact and lightweight design
- Horizontal or vertical installation
- Low noise E-field antenna as symmetrical
- Can be powered either by a conventional plug power supply (5,5 / 2,1mm round plug) or via USB with an optional cable
