The most common type of satellite dish nowadays is offset. It makes a better usage of the signal (as compared with front feed satellite dishes, and for the same conditions, the offset satellite dish would have a smaller diameter). Furthermore, given their design, they will always have a smaller lean as compared to front feed antennas, which make them suitable for wall mounting.
The diameter of the satellite dish is always associated with the satellite towards which you wish to direct the antenna (you will need to check the diameter based on the selected satellite). A higher disc diameter produces a relatively low increase of the signal level; however, it significantly increases signal quality or robustness in the reception. If possible, select the higher dish diameter to ensure proper reception, even under strong wind and rain conditions. The minimum recommended diameter (generic) is 80 cm for individual use and 1 m for collective use (both for Hispasat or Astra 19º satellites, for example).
Yes, it always is. Both iron and aluminium satellite dishes are currently marketed. Despite being more expensive, the latter are specifically designed so that they don't rust over the years. By investing a little bit more in the satellite dish you will have a quality product that will not rust over the years. Bear in mind that both the satellite dishes and the anchoring systems must be high quality. Look for aluminium satellite dishes and hot-galvanized anchoring systems if you wish to have products that will not rust over the years.
There are six basic LNB models in the market: Single, Twin, Quad, Octo, Quattro, and Monoblock. The SINGLE model is used for a single satellite receiver. The TWIN model allows you to connect two satellite receivers to a single LNB, both receivers being fully independent from one another. Likewise, the Quad and Octo models allow you to connect 4 and 8 receivers respectively, all working independently. The QUATTRO model is for “professional" use: it is conceived for use with multiswitches or signal processing headends. Finally, the LNB MONOBLOCK model allows you to capture signals from two satellites (Astra 19º and Hotbird) using a single satellite dish.
The Optical Fibre interface installed in the H45 or H60 field strength meters allows you to perform optical measurements directly through the optical fibre. It can be powered by connecting a coaxial cable in parallel with the FO to the RF input of the meter and applying voltage like a regular LNB.
Yes and no. In other words, it can be done, but without having any assurance that all the available channels will be actually received. During the pointing process of a dish without a meter, we are capable of detecting the desired satellite to watch the desired channel, but we will not have any assurance that we will be able to watch all the channels broadcasted by that satellite. The field strength meter not only allows us to point the parabolic antenna to capture a higher signal level and a better quality, but also to ensure that both the vertical and the horizontal polarities are perfectly aligned with the received signals. If we cannot guarantee this, we will likely lose some signals both of the horizontal and vertical polarities.
There could be several reasons for this. If you can't see any of the channels, the wind might have shifted the dish causing it to lose the correct direction. It could also be due to LNB supply damage or LNB damage. If you are only missing some of the channels, it is likely that the transmission frequency of those channels has changed. You will have to perform an automatic search in the satellite receiver itself.
If your receiver has the Diseqc switching feature, you can add a Diseqc selector switch in your installation and switch among up to 4 satellite dishes.
Yes. Despite the fact that you can power a single input out of the 4 inputs of the LNB to make them all function, we recommend powering the LNB through several of its inputs. The headend units must be programmed to supply 13 VDC. To program this parameter, you need to select LNB supply => 13 -- on the extended menu.
The LNB Monoblock allows you to receive the signal from two satellites (Astra and Hotbird) using a single satellite dish. This option allows you to access almost twice the channels on your satellite receiver.
No special items are required for the reception of this type of signals. Circular polarity is nothing but a linear polarity that continuously changes plane. Therefore, circular polarity will be received (with a slight loss) with a conventional linear LNB (either on H or V).
The LNBs are to be slightly turned to achieve an appropriate discrimination of the polarization. For the LNB with ref. 7475, when receiving a satellite positioned on the east (Astra, for example), the cable goes slightly to the right (when you face the dish). If the satellite was positioned on the west (Hispasat, for example), the cable should go almost in parallel with the floor, towards the right. For other LNBs, and for the east satellites, the cable goes to the left. For the west satellites the cable goes to the right. Anyway, it is recommended to always use a field strength meter to achieve the best possible polarity discrimination.
