C Band Satellite Dishes
A C band satellite allows for TVRO satellite reception. In the electromagnetic spectrum, the C band is at the microwave frequency range. The C band is at the 4 to 8 GHz range. The C band is also historically significant to commercial broadcasting as it was the first frequency band that was made available for ground-to-satellite communications for commercial use. The usual downlink for a C-band satellite is at 3.7 to 4.2 GHz. For the uplink side, it is at 5.926 to 6.425 GHz.
A C-band satellite is usually for open satellite communications. Commonly, it is used for full-time satellite TV networks, subscription programs and raw satellite feeds. C-band satellite communication is also famous in connection with TVRO satellite television system and the large C-band satellite specific reception dishes that it requires.
In order to get C-band satellite reception, it is necessary to install a C-band satellite reception dish in the area. The installation of the dish has its own requirements as well as C-band transmissions is prone to specific disturbances if it is improperly installed.
When assessing an area for suitability for a satellite dish, the most important thing to remember is that the satellite dish needs to have an unobstructed view of the entire C-band satellite positions. Thus, the area needs to have a clear view of the entire sky. Therefore, it is necessary to consider the natural foliage of the area as well as any man made constructions which may introduce interference.
The transmission frequency range used by the C-band satellite can also be interfered by any transmissions in the area which enter into the 3.7 to 4.2 Ghz range. If signals using these frequencies are present, this can cause reception problems.
A good way to detect for any frequency interferences is to use a reliable LNB in conjunction with a signal strength meter. In order to detect any interference, the LNB should be moved in a circle in the area where the satellite is to be installed. Any signal spikes detected during this will indicate that interference can be expected after the installation of the dish.
The actual installation of the C-band satellite reception dish is also a highly sensitive operation. The C-band satellite reception dish will require a very stable base in order to be able to receive accurate tansmissions through the C-band as well as through the Ku-band. In this regard, it is highly advisable to strengthen the base of the satellite dish not only with concrete but also with an iron core. It is also advisable to enforce the pole with concrete as well.
The dish used for C-band satellite communications commonly require large satellite dishes. These measure anywhere from between ten feet to three meters across. They are usually made either of fiberglass or of metal meshes.
C-band satellite transmissions are usually ideal for remote areas where cable connections are difficult and where common aerial transmissions are very difficult. This areas can include remote areas in the desert, in island locations or in mountainous regions. Fortunately, most of these areas can easily accommodate a satellite dish for C-band satellite transmissions.
