Low noise block downconverter ( LNB )
Most of a satellite dish is just plain metal. The only part that contains any electronic components at all is in the front of the metal arm. It’s generally referred to as an LNB or sometimes LNBF, which stands for Low-Noise Block downconverter. (Depending on your satellite TV . 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 them down the cable to the indoor receiver.

LNB stands for “Low Noise Block downconverter”, and is the box that sits on a pole pointing to the middle of a satellite dish. The LNB pulls in the satellite signal that’s reflected from the dish and sends it to a set-top box. Types of LNB. There are many different types of LNB out there – depending on the type of satellite dish and the satellite service you’re looking to get. Aug 14, · The LNB is the part on a satellite television dish that is installed at the pipe centered to the dish antenna, its like straight arm. “LNB” stands for “low noise block-down” converter, and is often referred to as the “eyes” on the dish. Dec 24, · The LNB (Low Noise Blocker) on your Satellite Dish is the piece of equipment on the dish that receives the information from the satellite in the sky and sends it to the receiver that is hooked up to your television.

Find a location for the dish antenna with a clear line of sight and a sturdy mounting surface 3. Mount the mast, making sure it is absolutely vertical 4. Assemble the dish antenna, setting the skew and elevation angles in the process.
Use additional skew bolts for skew angles greater than or less than 70 5. Mount the dish antenna on the mast and point the dish to the azimuth angle 6. Run cables between the dish antenna and the receiver s , leaving a service loop around the Mast Clamp 7. Using a peaking meter attached to the DPP Tighten all bolts see Table 1 and re-confirm maximum signal Note: The Connect the receiver cable s to the DPP Some restrictions apply when connecting Legacy receivers.
Install additional receiver s , if necessary If applicable, connect a second satellite dish to the DPP Assembling and Mounting the Dish Follow these instructions to assemble the satellite dish, mount it, and point it in the direction of the satellites. Note: If your skew angle is at the extreme ends of the scale greater than or less than 70 , insert nuts and bolts from the hardware pack into the additional skew holes.
These additional skew holes provide greater stability to the dish at these extreme angles. See Figure 2. Installing the Receivers Use the steps below while referring to Figure 1.
From the Point Dish screen, run Check Switch. On all other Legacy models, select Test. When the Check Switch procedure finishes, you should see an Installation Summary screen similar to the ones shown below. Do not disturb the receiver during the process of downloading software. If exiting the Point Dish screen does not start the download process, turn off the receiver for at least 20 minutes on most receivers to allow the receiver to take a software download.
Run Check Switch again and confirm reception for all three satellites on all available satellite tuners. Your Installation Summary screen should be similar to the ones shown above in step 8.
Some software on some models may identify the DPP This identification is OK. If installing an additional receiver, follow steps Welcome Sign In Register. Call Our Experts. Sherman Johnson C. Figure 1.
DISH Using the azimuth and elevation angles, find a location for the satellite dish where it can be pointed towards the satellites located at these angles. Make sure nothing blocks the line of sight between the dish and the satellites. Mount the mast to a solid surface so that the dish antenna cannot move or be bumped out of alignment.
Never mount to a tree or a public utility pole. Align the top part of the mast so that it is absolutely vertical. If the top part of the mast is off vertical by only a few degrees, it will be difficult or maybe even impossible for you to find the satellites. Take at least two readings with a level, on the upper mast, that are 90 degrees apart from one another.
Loosen both skew bolts and set the skew by rotating the dish mounting bracket to align the mark with the required angle on the skew scale which you wrote above.
Tighten the skew bolts securely. See Table 1 for the required torque values. After the skew is set, do not try to finetune the skew angle when aiming the dish.
Grounding, other devices, and in-home cabling must also meet these requirements. RG-6 coaxial cable rated for at least to MHz must be used in this installation. Do not use existing cables such as RG as it may cause signal loss. Also, be sure that any outdoor connections are made using waterproof F-connectors rated for MHz or greater.
The cable length between the DISH Damage caused by over-tightening is not covered by the limited warranty. Tighten all indoor coaxial cable connections to the receiver only by hand. If you use a wrench, you may over-tighten the connections and damage your equipment. Connect a temporary cable to a peaking meter. Thread the other end of the cable through the LNBF arm and bracket. Attach the LNBFs to the bracket using the included screws. Do not adjust the skew. Ensure you are peaking the dish using transponder 11 or higher.
With the peaking meter still connected, tighten the mast clamp and elevation bolts using the torque values listed in Table 1 on page 6. Re-confirm signal strength after tightening the bolts. Remove the temporary cable used for peaking the dish.
Thread the cable s from the receiver s through the LNBF arm and bracket. Connect a cable from DPP If a Legacy receiver is present, it should be installed last. Connect a cable from the DPP A splitter or other device will not work in this configuration.
