Overview
The 160-meter amateur radio band spans approximately 1.8 to 2.0 MHz, making it the lowest-frequency HF band available to amateur operators. Known as the “Top Band,” it is prized for long-distance nighttime communication and challenging antenna design.
Common Frequency Uses (Region 2)
- 1.800 – 1.810 MHz — CW, digital modes
- 1.810 – 1.843 MHz — CW and narrowband modes
- 1.843 – 2.000 MHz — SSB phone and other voice modes
Propagation Characteristics
Signals on 160 meters primarily travel via ground wave during the day and skywave at night. Winter months provide the best DX conditions due to reduced atmospheric noise and longer hours of darkness.
Typical Antennas
- Quarter-wave verticals with ground radials
- Inverted-L antennas for limited space
- Large horizontal loops
- Beverage receiving antennas for weak signals
Operating Tips
- Operate during nighttime for best DX.
- Use low-noise receiving antennas when possible.
- Watch for regional band plans and contest activity.
- Be mindful of strong atmospheric noise levels.
