FLG100LN
LOW NOISE REPLICA AMPLIFIERS: MAXIMUM PERFORMANCE FOR DX ANTENNAS!
FLG100LN
Boost your station with replicas of the legendary Wellbrook ALA100LN and FLG100LN amplifiers. These amplifiers are designed to extract the maximum clean, low-noise signal from your large and directional antennas.
Choose the specific amplifier to optimize your RX antenna:
1. VARIANT: ALA100LN (Low Noise)
Ideal for: Large magnetic receiving loops (up to 10 meters total diameter).
Specialization: Specifically designed for low bands (VLF/LF/MW/low shortwave). Extreme sensitivity and low noise.
Usage: Optimal for coupling with inductive loops.
2. VARIANT: FLG100LN (Low Noise)
Ideal for: Resistively terminated directional antennas, such as FLAG or KAZ (K9AY/short Beverage) antennas.
Specialization: Perfect for directional DX and noise rejection on medium wave (MW). Crucial for maximum directivity.
Usage: Designed for antennas that require specific input termination.
Fundamental Technical Details
Circuit Core: Both variants are based on the same High Intercept Point (High IP) scheme, ensuring clean reception free from intermodulation.
Professional Casing: The amplifiers are mounted in a robust 3D printed PETG box, a material known for its high resistance to heat, impact, and weather. Perfect for open-field installation.
Power Flexibility
Available in two options to suit your setup:
With T-Bias (Bias-T): To send power directly over the coaxial cable.
Without T-Bias: If you already own a Bias-T or prefer separate power.
Crucial Technical Note
The Structural Difference:
The ALA100LN amplifier is electrically identical to the FLG100LN, but lacks the TDK toroid (coupling/termination transformer) at the input.
This physical omission is what makes it specific for use with inductive loops, while the FLG100LN (with toroid) is specific for resistively terminated antennas (FLAG/KAZ).
Choose your model and transform your antenna into a DX excellence!
