Antennas : 160M- Antennas for 160m
- The best results work when you have an antenna with a large vertical component. It is difficult to get a horizontal antenna (dipole) high enough to be an effective antenna on 160. However, there are several easy things you can do with your present antenna to initially get on the best amateur radio band
