Icom AH-705

Icom AH-705

HF/50 MHz AUTOMATIC ANTENNA TUNER

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

Icom AH-705Covers the 1.8 MHz to 50 MHz bands

30 m, 98.4 ft or longer antenna: 1.8 – 54 MHz,

7 m, 23 ft or longer antenna: 3.5 – 54 MHz

* Depending on operating conditions or environments, the tuner may not be able to tune the antenna.

SO-239 antenna connector for 50Ω 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 x 105 x 40 mm; 7.5 x 4.1 x 1.6 in, 450 g; 15.8 oz* compact design

* Battery cells are not included.
