# What do hams mean when they refer to “higher bands”

For example, the Ultimate3S kit info page says:

Produces 250mW RF output on 30m (lower output on higher bands)

Would bands "higher" than 30m mean:

• bands with higher frequency e.g. 20m/17m/15m?
• bands with higher wavelength e.g. 40m/80m/160m?

It seems like an ambiguous way to refer to the "height" of a band rather than either its frequency or wavelength directly, so whenever I see this usage I am uncertain.

• In the olde days the 160meter band was called "Top Band" – Autistic Jan 31 '16 at 4:33
