Covering an extensive frequency range from 1.8 MHz to 50 MHz, this tuner is capable of handling various antennas, including a 50Ω dipole or Yagi. Whether you have a 30-meter or longer antenna (1.8 – 54 MHz) or a 7-meter or longer antenna (3.5 – 54 MHz), the AH-705 has got you covered.
Equipped with a SO-239 antenna connector, this tuner ensures a seamless connection between your antenna and radio. Plus, it offers two power source options – you can use alkaline batteries or an external 13.8V DC power supply, providing flexibility in different scenarios. Just remember, it’s recommended to connect the 13.8V DC power directly to the tuner, not through the IC-705.
Designed with IP54 dust protection and water-resistant construction, the AH-705 guarantees durability and reliability. However, to prevent water from seeping into the connection, make sure to cover the connectors with adhesive tape or a jack cover.
In conclusion, the Icom AH-705 HF/50 MHz Automatic Antenna Tuner is a powerful and versatile tool for optimizing your radio performance. With its wide frequency range, multiple power source options, and user-friendly operation, this tuner is a must-have for any IC-705 user. Experience enhanced communication and maximize your radio’s potential with the AH-705.
