Operation of satellite television antennas when converting from MPEG2 to MPEG4

Changes of this kind are inevitable and are dictated by the very spirit of the times. First of all, they are necessary to save a satellite resource, because in connection with the increasing number of HD channels, the frequency band used during their broadcasting is expanding, which means that the cost of renting a resource also increases. The transition to the MPEG4 format allows for more “compact” encoding of video streams, narrowing the band occupied by them. In combination with the DVB-S2 broadcasting standard, which increases the speed of information transfer, this transition provides significant savings Continue reading

Types of Satellite Antennas

Satellite antennas are made as solid / all-stamped, mesh and precast / sectional. The solid ones are made of a whole metal sheet and have a shape without technical holes and joints. Their signal reception quality is better than the others, and the design is less prone to kinks and defects during operation.

Mesh antennas are assembled from strips, forming a receiving grid. Their advantage is less windage, so mesh satellite dishes are preferred in areas with increased wind load.

Prefabricated antennas are made of petals and can be compactly packed for transportation and long-term storage. They, like sectional ones, are convenient for regular transfer, as they are easy to fold and allow you to quickly deploy the system. Cons of the design – in the weak joints of the petals, which are easily broken and require regular professional maintenance.

Mesh satellite dishes have slightly worse signal quality than all-metal antennas, but not due to technical holes. Since for the correct reflection of the beam the shape of the mirror must be strictly parabolic, it is Continue reading
