Applications
- Amateur (HAM) Radio
- High-power CB Radio setups
- Antenna feedlines
- RF signal transmission in commercial and military applications
Notes:
- RG-213 has lower attenuation than RG-58 and RG-8X but is thicker and heavier.
- The non-contaminating jacket makes Davis RF RG-213 suitable for outdoor installations where UV resistance and weatherproofing are critical.
