Welcome to the convenience of satellite TV, and other types of 'data transmission', sent directly to your home by way of a parabolic dish-shaped antenna designed to receive microwaves from various communication satellites orbiting above our earth. For these satellite dishes to clearly receive signals in some parts of our Northern Hemisphere, they must be positioned facing south.
As satellites move around their geosynchronous orbit around our earth, a popular type of dish with enthusiasts is the kind mounted on a pole and driven by a controllable servo motor; these can rotate to face any desired or broadcasting position. Many satellite receivers support all the popular satellite standards; depending on your location and the particular satellite sending the signals.
In Canada, most of the major Television and Telecomm suppliers that serve cable TV and computer hook-ups, have a satellite dish and service that will meet your communication needs. For pleasure, entertainment, and business, satellite meets that demand with huge monthly savings over direct hard-wired connections.
Most satellite systems come with a receiver unit, that is placed beside your TV; a remote, and a satellite dish installed somewhere near your roof or homes fascia; and if it's a really big unit, on a concrete pad in your yard of flat roof. The costs range from no money down to $300.00 dollar HD systems, and up; with regular subscription payments of $29.00-$39.00 per month all inclusive; except for the pay TV stuff; which is usually priced extra as per event.
Atmospheric conditions can cause poor signal reception; things like storms, heavy cloud cover, and even rain, have been known to disrupt the signal strength of satellite systems; including and especially, where the dish is placed in your home, and its positioning towards the sky. The surrounding areas should be taken into consideration; including, nearby buildings, trees and branches, as these can also affect your signal. The experts suggest that cold winter and a hot summer are the worst times to install a dish, as these cold/hot conditions can also influence reception.
Depending on ones location, one can experience two sun outages (not related to sunspot activity) a year, when the sun is behind the dish in its orbit, and casts a giant shadow towards the earth; it is here, and under the cast of the shadow that reception becomes severely disrupted. Your satellite dish signal strength is also a function of the size of the dish; usually the bigger the dish, the better the reception.
Reception problems may result from power supply problems within the receivers. To correct this type of problem may just require turning the power off and unplugging the unit for a few seconds; and then, plugging it back and turning it on. This will usually reset things. All satellite dishes require regular maintenance; inspecting for rust, and lubricating the bolts and joints with a sealant or Vaseline.
Finally, the cable between the dish and the receiver may be loose, and can also be the source of any poor reception. Consult with a professional satellite service company that knows what they are doing, and can calibrate your dish as needed, so as to achieve the best viewing results.
