ICOM AH-705 HF/50 MHz Automatic Antenna Tuner

Compact Antenna Tuner for the IC-705, Tunable 50 Ω Antenna and Long Wire Antenna

• Covers the 1.8 MHz to 50 MHz bands: 30 m or longer antenna: 1.8 – 54 MHz. 7m or longer antenna: 3.5 – 54 MHz
• SO-239 antenna connector for 50 Ω antenna such as dipole or Yagi
• 2-way power sources using alkaline batteries or external 13.8 V DC (* 13.8 V DC should be taken directly from an external power supply, not through the IC-705.)
• IP54 dust-protection and water resistance construction (* The connectors should be covered with an adhesive tape or a jack cover to prevent water seeping into the connection)
• Full automatic tuning, just push the [TUNER] button on the IC-705
