CopperWeld® 18 AWG Antenna Wire – Lightweight Copper-Clad Steel for Portable HF Antennas

CopperWeld® 18 AWG antenna wire is a lightweight copper-clad steel conductor designed for compact HF antenna systems where weight and cost savings are priorities. While thinner than heavier gauges, it still offers reliable strength and conductivity for shorter runs, field operations, and temporary setups.

Why Choose 18 AWG CopperWeld® Wire?

• ✅ Steel Core Durability – Resists stretch and breakage better than soft copper wire
• ✅ Lightweight & Easy to Deploy – Ideal for quick setups and portable systems
• ✅ Reliable Signal Performance – Copper cladding provides efficient RF conduction
• ✅ Affordable – Cost-effective option for compact or low-power HF antennas

Recommended Applications

• ✅ QRP and portable HF antenna systems
• ✅ Shorter dipoles, EFHWs, and long-wire configurations
• ✅ Emergency and temporary communication setups
• ✅ Educational or experimental wire antenna projects
