Key Takeaways
- 50 ohms is an industry compromise — not a law of physics.
- Most common amateur wire antennas are closer to 75Ω than to 50Ω.
- 75Ω coax has lower loss than 50Ω coax of comparable diameter.
- Lower loss can outweigh the mismatch penalty — delivering more power to the antenna.
- It's not right for every situation — but for many, it's not just adequate, it's superior.
