A satellite dish is a satellite dish used in data transmission, such as television broadcasts for satellite television services. There are many different types of satellite dishes. Some dishes are huge and are used for astronomical endeavors, such as the program Search for Extra Terrestrial Intelligence (SETI). Other satellite dishes are small and are used to listen to HDTV in your home.
Portable satellite dish
A portable satellite dish is a satellite dish that you can take with you wherever you go. More than one company makes these dishes, and they come in different shapes and sizes. For example, XM Radio, a satellite radio company, made small, pen-like portable satellite antennas that were used on XM portable receivers. VuQube also makes a portable dish called VQ1000. This product is used by people who like to watch TV while camping, or in their summer cottages. According to portablesatellitedishes.com, portable disks such as the VQ1000 can also hold the signal due to bad weather conditions, something permanent satellite TV disks have problems with.
Different satellite dishes work in different frequency ranges. C-band satellite dishes operate in the range of 4 to 8 gigahertz (GHz). Due to these lower ranges, C-band satellite dishes are excellent TV antennas. But the C-band’s satellite dish is large and bulky. Nicknamed ‘Big Ugly Dishes’ (‘BUD’) because of their size, C-band satellite dishes are not very popular. Despite their size and lack of popularity, C-band satellite dishes are a cheaper alternative to smaller satellite dishes, as they are used by companies such as DirecTV and Dish Network.
HD satellite dish
HD satellite dishes are very similar to non-HD or standard definition (SD), satellite dishes in shape and size. The main difference is that HD antennas can receive HD signals while SD antennas are not. This is because the HD signal cannot be decoded by the SD satellite dish. HD satellite dishes are also available in two different forms: Move image group (MPEG) 2 and MPEG 4. MPEG files have to do with data transfer — the more MPEG files, the more data can be compressed and decompressed, and therefore it is faster data will come from one place to another. Satellite TV providers like Dish Network do away with MPEG 2 and only move to MPEG 4.
