Icom AH-705 AUTOMATIC ANTENNA TUNER

Description

• Covers the 1.8 MHz to 50 MHz bands

• SO-239 antenna connector for 50 Ω antenna such as dipole or Yagi
• “Terminal connector”, binding post socket adapter supplied for a long wire antenna
• 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
• Latching relays used for saving power consumption
• 190 × 105 × 40 mm; 7.5 × 4.1 × 1.6 in, 450 g; 15.8 oz* compact design
