CopperWeld® 12 AWG Antenna Wire – Copper-Clad Steel for Long-Lasting HF Performance
CopperWeld® 12 AWG antenna wire features a steel core with a copper-clad exterior, offering both high tensile strength and reliable RF conductivity. Ideal for amateur radio, military, and commercial HF antenna systems, this wire is designed to withstand long-term exposure and tensioned installations.
Benefits of 12 AWG CopperWeld® Wire
- ✅ Steel Core Strength – Provides excellent resistance to sag and stretch in long spans
- ✅ Copper Conductivity – Cladding ensures solid signal performance and corrosion resistance
- ✅ Balanced Gauge – Strong enough for permanent installations, lighter than 10 AWG
- ✅ Low Maintenance – Withstands UV, moisture, and wind stress over time
Common Applications
- ✅ Dipoles, long wire, and curtain array antennas
- ✅ Tower-to-ground RF bonding systems
- ✅ Field-deployed or semi-permanent HF antennas
- ✅ Counterpoise and radial systems for verticals
Specifications
- ✅ Gauge: 12 AWG
- ✅ Material: Copper-clad steel
- ✅ Diameter: ~0.0808" (2.05 mm)
