📡 Preamplificatore d’antenna – Adattatore di impedenza MW/LW

📡 Antenna Preamplifier – Impedance Matching Adapter MW/LW (PO/GO)

📌 Overview

This antenna preamplifier module optimizes radio signal reception by matching the impedance of a long-wire antenna to the input of one or more receivers. It provides a high adjustable gain, ideal for improving weak or difficult receptions.

🧰 Features

• Antenna preamplifier with impedance matching
• Compatible with MW / LW / SW (PO / GO / OC)
• 📐 Dimensions: 60 × 35 × 25 mm (including potentiometer)
• 🔌 Power supply: 5 to 12 V DC
• ⚡ Current consumption: 8 to 10 mA

📶 Performance

• Maximum gain MW/LW: up to 45 dB (×200 input signal)
• Gain at 10 MHz: approx. 20 dB
• 🎚 Adjustable gain via potentiometer (voltage control)

🔧 Connections

• 1 antenna input
• 1 output to receiver
• 2 power supply terminals
• Simple and quick installation

⚠️ Input Specifications

• Maximum input voltage (antenna): 0.6 V DC

🧠 Applications

• Impedance matching for high-impedance long-wire antennas
• Improvement of weak signal reception
• Ideal for vintage or low-sensitivity receivers (crystal radios, diode sets, classic radios)
• Signal distribution to one or more receivers
• Assists in tuning and adjustment of radio circuits
