Icom Compact Antenna Tuners AH-705

The transceiver described appears to be the Icom IC-705, a versatile and compact radio designed to cover the frequency range from 1.8 MHz to 50 MHz. It features an extensive tuning capability, accommodating antennas ranging from 30 meters (98.4 ft) or longer for the 1.8 – 54 MHz bands, to 7 meters (23 ft) or longer for the 3.5 – 54 MHz range. It's important to note that the tuner may face limitations in specific operating conditions or environments.

Connectivity options include an SO-239 antenna connector for 50 Ω antennas like dipoles or Yagis, and a "Terminal connector" with a binding post socket adapter for long wire antennas. The transceiver supports two power sources, allowing the use of alkaline batteries or an external 13.8 V DC power supply. However, it's emphasized that the external DC power should be directly sourced, bypassing the IC-705.

Constructed with IP54 dust protection and water resistance, the transceiver is designed to withstand challenging conditions. To prevent water seepage into connectors, it's recommended to cover them with adhesive tape or jack covers.

The IC-705 is equipped with a full automatic tuning feature, activated by pushing the [TUNER] button, simplifying the tuning process. Latching relays are utilized to conserve power consumption. The transceiver boasts a compact design, measuring 190 × 105 × 40 mm (7.5 × 4.1 × 1.6 in) and weighing 450 g (15.8 oz), making it suitable for portable and field operations.
