a cone-shaped tube, with the narrow end towards the LNB
an antenna system that handles the incoming waveform from the dish to the focal point
The feedhorn collects the reflected signal from the dish and sends it to the LNB. The feedhorn you need is determined by the types of satellites you want to watch: C-band, Ku-band, DBS, or all three. See Feedhorns.
The focal point assembly on a dish that collects the signal and changes the polarity, sends it to the LNB.
That part of a parabolic or grid reflector antenna which contains the driven element.
A section of waveguide into which signals from a parabolic dish reflector are aimed. In most parabolic antenna designs, the feedhorn is mounted at the reflector's focal point. The output from the feedhorn directly feeds the low noise block converter ( LNB).
A satellite TV receiving antenna component that collects the signal reflected from the main surface reflector and channels this signal into the low-noise amplifier (LNA)
A device resembling a horn that emits radio waves in a concentrated beam or collects and focuses radio waves that are incident on its aperture. In a receiving system it collects microwave signals reflected from the surface of the antenna. In a transmitting system it directs microwave signals onto the reflector surface for focussing into a narrow beam aimed at the satellite. The feed is mounted at the focus of the parabolic reflector. It is usually designed to match a particular antenna geometry (F/D ratio).
A piece of antenna hardware, located at the focal point of the parabolic reflector, that radiates RF energy toward the antenna reflector and collects (received) RF energy from the antenna reflector.
In satellite broadcasting, a part of a receiving antenna, usually a dish, that collects the signal reflected from the main surface reflector and channels it into a low-noise amplifier.
Typically the center-point or focal-point of a downlink dish. The dish (parabola) focus the energy on this location. The LNB is inside.
