Multiple Choice

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

When you connect an SSB automatic tuner to an insulated backstay, the backstay becomes a live RF conductor and must be insulated and able to withstand the RF voltage and outdoor conditions. A wire used here should provide good insulation, weather resistance, and adequate voltage rating so there’s no arcing to the mast or nearby metal parts. GTO-15 high-voltage cable is designed for outdoor, high-voltage RF applications and offers durable insulation suitable for use with an insulated backstay. It handles the RF power without breakdown and protects against arcing, making it the best choice for this connection. Coax types like RG8U or RG213 are shielded feedlines intended to carry RF signals to an antenna, not to serve as the primary insulated conductor from a tuner to a backstay. A simple 16-gauge two-conductor wire lacks shielding and outdoor insulation, making it unsuitable for this high-voltage, weather-exposed setup.
