Important for tracking satellite systems
Introduction: Welcome to the world of tracking satellite systems!!! There is much more to the world of satellite TV than fixed little dishes that look at only one satellite. It takes a little more effort to install a tracking satellite system. However, with a good understanding of the equipment options and if the adjustments on the tracking/tuning page are performedFootprints by Dish Size - Adjusting the Polar

You should have an unwarped satellite dish, and a perfectly vertical mounting pole, it will make things easier. This site deals with prime focus (or center focus) satellite dishes, meaning incoming signals are directed to a point.at the center of the dish. It is impossible to cover every detail in a site such as this, otherwise the pages would never load!! Some details, such as using UV resistant tie wraps to tidy your cabling is common sense. And for pole installation, covered in detail on a companion page, is ground poles in concrete and mounts on concrete pads as well as a brief discussion on wind loading. For an azel mount, i.e. not a polar tracking mount, proceed directly to the azel mount setting notes. NOTE: Azel mounts are used when you have no intention of moving the dish to another satellite as in the case of a system feeding video into a hotel or apartment complex or other similar cable distribution system; if this is the case, then use an azel mount as they are more stable than polar mounts. GENERAL OVERVIEW: Television satellite signals originate from Footprints by Dish Size - Adjusting the Polar Mount for Prime Focus- C/Ku-Band Satellite Systems - Tuning, Tracking, Azimuth, Elevation, Declination Angles, F/D Ratio, Focal Distance, Inclinometer, LNB/Feedhorn Assembly, Ground Pole,Waterproofing, Rain Fadea single 'uplink' facility and are transmitted to a communications satellite orbiting 22,300 miles above the earth's equator. These type orbiting communications satellites are considered to be 'parked' in orbit; though in reality they travel from west to east but appear stationary to an observer on Footprints by Dish Size - Adjusting the Polar Mount for Prime Focus- C/Ku-Band Satellite Systems - Tuning, Tracking, Azimuth, Elevation, Declination Angles, F/D Ratio, Focal Distance, Inclinometer, LNB/Feedhorn Assembly, Ground Pole,Waterproofing, Rain FadeEarth because their speed is the exact speed of the Earth's rotation thus they are termed geostationary satellites. The overwhelmingly common receive frequency of satellite transmissions, for video purposes, are either in the C-band (frequency range from 3.7 to 4.2 gigahertz) or in the Ku-band (10.7 to 11.7 Ghz and 11.7 to 12.75 Ghz). New generation satellites are being built with Ka-band capability (22Ghz) and a very few, older specialty satellites are in the lower frequency S-band. After receiving the signals from earth, the satellite amplifies the signals then rebroadcasts them, or 'downlinks', back toFootprints by Dish Size - Adjusting the Polar Mount for Prime Focus- C/Ku-Band Satellite Systems - Tuning, Tracking, Azimuth, Elevation, Declination Angles, F/D Ratio, Focal Distance, Inclinometer, LNB/Feedhorn Assembly, Ground Pole,Waterproofing, Rain Fade earth in a predetermined beam pattern commonly called a 'footprint'. The calibration of the footprint is in EIRP (effective irradiated power) and its units are in dBw (decibel watts). The downlinked signal from the satellites, upon reaching the earth, is very weak not only because of the great distance the signal has traveled but also because of the 'spreading' effect of the signal from a point source at the satellite to a regional image at its footprint. To begin the process to receive this signal, in effect, a satellite dish is a passive amplifier in that it 'collects' the weak signals from space, thus the bigger the dish the greater the signal amplication which is why a larger dish is required to receive satellite signals that are weak into your receiving location. A satellite dish Footprints by Dish Size - Adjusting the Polar Mount for Prime Focus- C/Ku-Band Satellite Systems - Tuning, Tracking, Azimuth, Elevation, Declination Angles, F/D Ratio, Focal Distance, Inclinometer, LNB/Feedhorn Assembly, Ground Pole,Waterproofing, Rain Fadecollects these weak signals and focuses (reflects) the energy to a central spot known as the focal point or focus. All satellite dishes are designed according to a family of mathematical formulae known as parabolas (dish design formula). All incoming signals to a parabolic reflector are 'bounced' to the same point - this point is known as the focus (or focal) point of the dish. Ideally, all incoming signals from the orbiting satellite are reflected to the focal point. If the dish is properly installed and has no major surface irregularities, the reflected incoming energy will be tightly concentrated at the focus, therefore maximizing dish gain. Note that an offset dish is simply a section of the total parabola. |
