PL-259 or Type-N Connectors | LMR-400 Equivalent | HAM & GMRS Ready
Upgrade your radio setup with KMR400 low loss coaxial cable, designed for serious HAM radio and GMRS operators who demand maximum performance. If you’re still using RG8X or lower-grade coax, you’re losing valuable signal before it even reaches your antenna.
📡 Why Choose KMR400 Coax?
At VHF and UHF frequencies, coaxial cable loss has a direct impact on:
- Transmit range
- Signal strength & clarity
