crossband
Very LowTechnical/Specialized
Definition
Meaning
To form, arrange, or mark with a band, stripe, or pattern that crosses or intersects.
A technical term used in electronics and radio (especially regarding antennas) to describe the capability of operating on two different frequency bands simultaneously, often for repeating or linking signals.
Linguistics
Semantic Notes
As a verb, it describes a physical act of marking or arranging in a crossing pattern. In electronics, it functions adjectivally (e.g., crossband operation) to describe a specific technical function.

Learning
Memory Aids
Mnemonic
Imagine a CROSS made of rubber BANDS. It links two different sides (like two different radio frequencies).
Conceptual Metaphor
BRIDGING/CONNECTING DIFFERENT WORLDS (linking separate frequency bands).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить дословно как "скрещенная лента". В техническом контексте: "междиапазонная связь", "ретрансляция между диапазонами".
- Не путать с "перекрестной полосой" в контексте графики или дизайна, где это может быть неверно.
Common Mistakes
- Writing as two separate words: 'cross band'.
- Confusing it with 'crossbite' or 'crossbar'.
- Using it as a common verb outside of technical contexts.

FAQ
Frequently Asked Questions
No, it is a very low-frequency, specialized term used almost exclusively in technical fields like radio communications.
Its primary use is as an adjective (e.g., crossband operation) or a verb (to crossband). It is rarely, if ever, used as a standalone noun in modern English.
While both relate to multiple frequencies, 'dual-band' typically means a device can operate on two bands separately. 'Crossband' specifically refers to the ability to receive on one band and simultaneously transmit on another, linking them.
In British English, it's /ˈkrɒsband/. In American English, it's /ˈkrɔːsˌbænd/. The stress is on the first syllable: CROSS-band.
