Beverage antennas provide one of the least expensive and most reliable ways to improve DX capabilities on the low frequencies.
The RX small preamp is very simply low noise preamplifier module with 2SC5551 transistor based on W7IUV design. Use it as high IP preamplifier for RX antennas, buffer amplifier or small driver.
A bias tee is used to insert AC or DC power into an HF signal to power remote antenna preamplifiers (DC), Bi-directional beverages (AC) or other devices.
