LNB stands for "Low-Noise Block converter" and is a satellite dish head that converts the microwave signals from the satellites into a signal that is understandable for the satellite receiver. A universal LNB head receives both polarizations (vertical and horizontal) and the full range of frequencies in the satellite's Ku band.

A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.

2006年3月21日 · The abbreviation LNB stands for Low Noise Block. It is the device on the front of a satellite dish that receives the very low level microwave signal from the satellite, amplifies it, changes the signals to a lower frequency band and sends …

An LNB has two important functions: it’s a low-noise amplifier, meaning that it takes the extremely weak satellite signal and amplifies it. It’s also a block downconverter, meaning it takes the signals on the super-high satellite frequencies and converts them to lower frequencies.

LNB又叫高频头（Low Noise Block），即低噪声下变频器，其功能是将由馈源传送的卫星信号经过放大和下变频，把Ku或C波段信号变成L波段，经同轴电缆传送给卫星接收机。

The LNB, which stands for Low Noise Block is the attachment at the end of the satellite dish in which the coaxial cables that feed your satellite receiver connect to.

LNB又叫高頻頭(Low Noise Block),即低噪聲下變頻器,其功能是將由饋源傳送的衛星信號經過放大和下變頻,把Ku或C波段信號變成L波段,經同軸電纜傳送給衛星接收機。

2023年2月14日 · Once I dialed in a satellite and tweaked the lnb placement, I drilled my hole and permanently mounted my new lnb bracket. Works like a charm. I think the most important part is to make sure the HughesNet lnb head and the new FTA lnb head are in the same position and pointed to the same place on the reflector.

With Orbital LNBs, you get the latest technology for your satellite terminal, very low phase noise, excellent local oscillator (LO) stability, consistent linearity, and long-term reliability – in a small and lightweight package.

An LNB or frequency converter head is mounted on the arm of the satellite antenna to receive TV and radio programmes through housing sockets
