Today's cars have multiple antennas. The car's design does not usually allow these antennas to be positioned vertically in the center of the car roof, although this would provide optimal functionality. A compromise must be made between design and function. This makes it all the more important to test the receive level of UHF digital TV antennas in real-world operation.

In recent years, the proliferation of transmitters, receivers and communication devices in homes, cars and offices around the world has been phenomenal. This explosion in radio communications has stressed the radio frequency spectrum and increased the risk of disruption in reception and the number of problems encountered when using electronic equipment. Industry Canada, through its Spectrum Management Division, has developed a set of tools to help you:. Despite a substantial increase in the number and type of communication and broadcast systems that are potential sources of interference, almost half of signal reception problems are due primarily to faults or defects in the radios, televisions or other equipment we use. Antennas and antenna lead wires can also cause reception problems.
The site informs visitors not only about the amount of free over-the-air programming available, but also provides essential information about which television antenna type.

These misleading scams have been around for several years. The concept marginally works when the owner attaches it to a window, which gives it more signal to work with than an antenna placed in the corner of a room. In fact, it is a website that reviews products, but has a financial incentive to write glowing reviews to encourage you to buy whatever they write about. Goodsavingstips stretches the truth about the ClearView antenna more than a salt water taffy machine on the Atlantic City Boardwalk:. Millions of Americans are doing just that, thanks to a brand new rule in that allows certain regions access to free TV. Thankfully, if you live in an area where this new rule went into effect, you no longer need to give your hard earned money away to the big cable companies. As a result, Americans are now cutting the cord on their cable companies in record numbers, saving them thousands of dollars. Ever since this rule went into effect, the big cable companies are panicing [sic] because many Americans will no longer need to pay for cable or satellite tv to get their favorite channels in HD. As long as you live in a publicly broadcasted [sic] area, it is now possible to watch all of your favorite channels for free with a TV antenna. Boastful claims about the TrueSignal antenna. Several antenna companies market their antennas using similar language.
TV & Radio
Broadcast towers are used for transmitting a range of communication services including radio and television. The tower will either act as an antenna itself or support one or more antennas on its structure, including microwave dishes. This fact sheet provides information about concern of adverse health effects arising from exposure to RF EME from broadcast towers. The ARPANSA Standard is based on scientific research that shows the levels at which harmful effects occur and it sets limits, based on international guidelines, well below these harmful levels. Broadcast towers supporting FM radio and TV antennas are placed on the highest point in an area so the transmitted signal has a clear path to receiving antennas. The transmitted signal is projected away from the tower almost horizontally so that as much area as possible is covered. This minimises the signal strength at ground level near the tower.

Or have we? A visit to your local big box store will reveal shelves of television antennas with a variety of price points and stunning performance claims. Our mobile and technologically advanced communication needs have pushed this research forward, with corporate giants like Apple investing billions of dollars into developing more powerful antennas for their smartphones and tablets; aerospace companies creating better simulators to test performance; and scientists working around the clock to ensure that an antenna the size of a postage stamp, can pack the power of a massive antenna structure. In the midst of this antenna renaissance, Antennas Direct dusted off old physics books from and began our mission to build a TV antenna, rooted in radio frequency science, to deliver the best TV antenna performance possible. We had predicted how the digital transition would transform the way people watch television and made the decision to invest millions in research and development, stepping in as the beneficiary of the many technological advances that were taking place and would continue to take place during this Golden Age. No other TV antenna company, not even the largest consumer electronics brands on the planet, followed suit.
