What type of wire would connect an SSB automatic tuner to an insulated backstay?

When an SSB tuner is connected to a long, exposed element like an insulated backstay, you need a lead that stays well insulated from conducting surfaces and can handle the RF voltage present on the antenna without arcing. The backstay acts as a large, unshielded conductor in the antenna system, and RF can appear as high voltage along it. Using a high-voltage, well-insulated lead keeps the RF on the wire and prevents arcing to the mast or rigging, which is essential for safe, reliable operation. GTO-15 high-voltage cable is designed for exactly this kind of application: a rugged, flexible, heavily insulated lead suitable for outdoor marine environments and for carrying RF without leaking or arcing. That makes it the best choice for tying the tuner to the backstay. Coaxial cables (like RG8U or RG213) are designed to carry RF with a shield, but they are not the right fit for attaching directly to a backstay that becomes the radiator, and they can complicate the impedance and mounting. A small 16-gauge two-conductor wire would be far too light for the power and would not provide the robust insulation needed to prevent arcing in a marine setting.
