30 meters band
“WARC band”
30 meters is a narrow, contest-free WARC band reserved for CW and digital modes — quiet, efficient, and open through much of the day and night.
Propagation & character
It bridges 40 and 20 meters: frequently open to DX in daylight and holding up into the evening, with low noise and reliable paths.
What 30 meters is used for
CW and digital only — FT8 is especially popular here. No phone operation, and no contesting by long-standing agreement.
Operating tips
- US power is limited to 200 W PEP.
- With no contests and no phone, it is a relaxed band for DX and digital ragchewing.
- A 30 m dipole is about 46 ft.
Antennas for 30 meters
A half-wave dipole for 30 meters is about 46.2 ft (14.1 m) end to end. Work out an exact starting length with the antenna calculator, then trim for lowest SWR.
