feedhorn
Very LowTechnical
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.

Examples
By CEFR Level
- The satellite dish has a small feedhorn in the middle.
- The technician aligned the feedhorn precisely to maximise signal strength.
- 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.
