  1. Copper braid removed from coaxial cable
  2. Copper-clad steel wire
  3. Flat copper strap ✔

Why: RF current flows mostly along a conductor's surface. A wide, flat copper strap has lots of surface, so it bonds equipment well at radio frequencies.

Huh, didn't know that: Bonding ties station equipment together electrically, which helps cut down RF problems.
