Features:
  1. High Impedance Matching: This amplifier transforms high input impedance to a standard 50-ohm output impedance, ideal for impedance matching and isolation in various passive antenna reception setups, such as loop, whip, and magnetic rod antennas.
  2. Versatile Compatibility: Suitable for a wide range of radio receivers and devices, including SDRs, walkie-talkies, and HackRF One. Compatible with multiple antenna types, such as Donut antennas, Mini Loops, and tuned loop antennas.
  3. Enhanced Reception Performance: The high input impedance maximizes energy extraction from the input antenna, minimizing signal loss due to unstable input antenna impedances, thereby significantly improving reception performance.
  4. Wide Bandwidth: With a 300 MHz bandwidth, this amplifier can handle signals across a broad frequency range, making it versatile for various applications.
  5. Long-lasting Operation: The 800mAh built-in battery provides extended operating time, exceeding 24 hours on a single charge, ensuring uninterrupted use during prolonged field operations.
Package Includes:
  • 1x High Impedance Amplifier
