Definition

Meaning

A flared, horn-shaped antenna component that channels microwave signals between a waveguide and a parabolic dish.

A specific waveguide assembly used in satellite communications and radio astronomy to efficiently collect or transmit signals to a dish antenna.

Linguistics

Semantic Notes

Always a noun; a compound of 'feed' (supplying signal) + 'horn' (describing its flared shape). It's a piece of hardware.

British vs American Usage

Differences

No significant lexical differences. Spelling is consistent.

Connotations

Purely technical in both varieties.

Examples

By CEFR Level

B1
  • The satellite dish has a small feedhorn in the middle.
B2
  • The technician aligned the feedhorn precisely to maximise signal strength.
C1
  • Modern multiband feedhorns incorporate complex waveguide transitions to separate Ka and Ku band signals efficiently.

Learning

Memory Aids

Mnemonic

Think: It 'feeds' the signal to the dish, and it's shaped like a 'horn'.

Conceptual Metaphor

A Funnel (directing energy into a specific path).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as 'рожок для кормления' (feeding horn for animals). It is 'облучатель' or 'фидерный рупор' in technical Russian.

Common Mistakes

  • Spelling as two words: 'feed horn'.
  • Using it as a verb.
  • Confusing it with the entire satellite dish.

FAQ

Frequently Asked Questions

No, it is a highly specialised technical term used only in telecommunications and radio engineering.

No, that is incorrect. In audio engineering, a speaker horn is just a 'horn'. 'Feedhorn' is specific to antenna systems.

The feedhorn is the flared front-end that collects the signal. The LNB (Low-Noise Block downconverter) is often attached behind it to amplify and convert the signal.

No, it is not a term used in general computing. It belongs to RF (Radio Frequency) engineering and physics.
