Satellite TV Tips
Satellite TV is a broadcasting service which allows subscribers to receive television signals through a dish-shaped receiver unit. These signals are originally uploaded to a communications satellite that is in a fixed orbit above the earth, and then electronically scrambled to prevent unauthorized downloading. Those who pay a subscription fee for satellite TV service are issued both the receiving dish and a descrambler. The actual tuning information is fed into the television through a cable, much like the earth-bound cable television services in competition with satellite TV providers.
Satellite TV solves many of the problems associated with earlier television broadcasting methods. Television stations originally broadcast their signals in two specific radio wave bands- VHF (very high frequency) and UHF (ultra-high frequency). Aerial antennas placed on roofs or attached to the television itself would receive as much of these radio wave transmissions as possible, but the results could be barely watch able depending on the strength of the signal, the terrain between the station and the television set, and the atmospheric conditions. Cable television systems could provide a better television signal, but this involved stringing miles of insulated wire and creating subscription services.
Satellite TV provides a strong digital signal to subscribers' television sets and is almost completely wireless. Earlier satellite TV systems used very large dish receivers in order to focus the distant signals onto a powered antenna. Since different television channels were located on different communication satellites, these dishes would have to physically turn to predetermined points in the sky in order to receive the proper signals. Because regulation of these early dishes was not uniform, illegal electronic descramblers became a lucrative underground market. Stiffer penalties for unauthorized descramblers paved the way for legitimate satellite TV subscription services.
Modern satellite TV services have streamlined the process. A single communication satellite now remains in a steady orbit above the Earth, allowing all subscribers to mount a much smaller dish receiver at a fixed point. Technicians from the satellite TV provider may install the dish or owners can determine the proper receiving angle and do it themselves. Instead of scanning various satellites for different channels, modern satellite television providers license the use of popular cable or broadcast channels. Much like a cable system, the tuner descrambles selected programs sent out on a specific frequency. This allows satellite providers the option of pay-per-view movie rentals or the blocking of adult-oriented or premium movie channels.
Satellite TV services are especially popular in rural areas with poor broadcast reception and/or no cable service. Purchase of a receiving dish is generally limited to homeowners, not renters. Satellite dishes must have a clear line of sight to the satellite itself for best reception. Some homeowners discover that a grove of trees or mountainous terrain can be problematic. Critics of satellite TV also mention reception problems during heavy rains or snowfall. Signals between an earth-bound receiver and a space-based satellite can be affected by atmospheric conditions between them, but other television services also have similar drawbacks. Many customers prefer the additional channels available on satellite TV systems and the clarity of the digital signals.

Internet Free Fax
What is Internet Fax?
Internet fax is a type of online service that provides subscribers with the ability to send and receive faxes without a fax machine. Instead, Internet access and an email account is all that is required.
To use an Internet fax service, a subscriber signs up for a small monthly fee and is assigned a fax number. When a fax is sent to the subscriber’s number, the service accepts the fax, turning it into a file that is forwarded to the subscriber’s existing email address.
To send an Internet fax, the subscriber creates an email. The fax content can be written in the body of the email, and attachments are normally permitted. The destination fax number is entered in the “To” field, along with “@” and the Internet fax service name. For example, if the fax number were 1-550-234-5678, the email would be addressed to 15502345678@site.com. In the “Subject” field the user enters the name of the recipient, “Attn: Mr. Jam” for example.
A small toolbar, available for download from the Internet fax service, is used as a plug-in inside the email program. Clicking on the “Send” button on the toolbar sends the email to the Internet fax service. Upon receipt, an automated program converts the email to a fax format, then faxes to the number supplied in the “To” header. The recipient receives the fax normally, through his or her fax machine.
This service can be very convenient. Of the many advantages, your assigned fax number is active 24 hours a day, so that your account can accept faxes around the clock. Contrast this with using a fax machine, which relies on your phone system being free to accept a fax. For those that use one phone line for fax, telephone, and dial-up, an Internet fax service is especially handy. Internet fax services also save paper and fax toner, and do not rely on a serviceable fax machine. All faxes are sent and received as files. They can be printed by choice, but it isn’t necessary.
A further advantage of an Internet fax service is that the subscriber does not need to be familiar with faxing software or fax machines. The convenience of sending and receiving faxes by using the familiar email interface appeals many people.
One of the best features of Internet fax services is that many offer toll-free fax numbers for the U.S. and Canada, so that your U.S. and Canadian clients can fax you for free. Sending faxes is also free of phone charges for the subscriber, as he or she is only sending emails.
When looking into Internet fax services, consider a service that offers a secure website. This provides a mobile “portal” to send/receive faxes while you’re on the road or away from home. Confirmation of sent faxes should be standard, so you can be sure your client got your communication. The ability to send to more than one fax number at a time can also be valuable. Check for a page capacity, as some services may limit the amount of pages the subscriber can send/receive in a month.
