Portable / SOTA Operation

The FT-857D is the main portable workhorse, and is used both portable when operating in SOTA and Backpackers, and as a mobile station coupled to a Yaesu ATAS-120A motorised antenna. This combination when configured correctly is excellent with the first contact after install being Brazil on 20m.

The following antenna's are used for portable operation;

  • 2m - Tonna 9-ele Portable Yagi Array
  • 2m - SOTA Beam 3-ele Portable
  • 6m - Moonraker 3-ele Yagi Array (modified for portable operation)
  • 4m - As 6m, but modified elements  and spacings.
  • 20m - Home-made SOTA Dipole (Pre-cut Inverted V configuration)
  • 20m - 40m - Home-made Dipole (Ladder-fed Inverted V configuration, tuned with SGC-211 Autotuner)
  • Yaesu ATAS-120A - mobile HF Screwdriver Antenna

Portable connectivity is via SSB Comms Aircell 7 or RG58U.
