• CG Antenna CG-3000 Remote Automatic Antenna Tuner

• Remember: An antenna tuning unit (ATU) does not retune the antenna to a different band; it only protects the transmitter from damage. It does not magically grant resonance or efficiency to an inherently inefficient antenna structure.
• Exceeding operational limits (power, frequency ranges) can permanently damage the antenna system, measuring equipment, or dummy loads.
• Always operate in QRP mode (low power) during tests and experiments to minimize risks.
