What is the HDTV antenna?

According to the federal mandate, all television stations in the United States will start broadcasting a digital signal in June 2009. Many stations have already made a transition to high -resolution television (HDTV) and replaced analog signals that were used from the invention of television service. Some spectators, especially a minority who receive local television signals with free air antenna, will have to upgrade their equipment or not receive transmissions.

Unlike popular believing, however, these viewers do not have to buy an antenna HDTV. Although the advertising for a special HDTV antenna has filled the press media and the Internet, the truth is that the HDTV antenna does not differ than other antenna. Digital television is broadcast primarily on ultra -high frequency belts (UHF), while analog signals were sent to a very high frequency (VHF) zone. Virtually all existing antennas are designed to receive both UHF and VHF.

These boxes, which are easily accessible and come with a government discount to $ 40 (USD), convert an analog signal to digital format. Antenna that receives a signal should not need any adjustments at all.

This means that there are several differences between digital TV and analog TV. The most important difference is in clarity, because the quality of HDTV image is much sharper than an analog variety. The disadvantage of HDTV, especially for those who live in peripheral reception areas, is that the signal can disappear completely in the time of bad weather. For analog signals, the reception was almost always available, even though it became snowy or unclear. With digital signals there is either a very clear picture or nothing at all.

Because in fact there is no difference between the "new" hdtvanténa and any other antenna, the same tips applies to improve income. Antenna located outsideFifty percent better signal than those located in the attic. The higher the antenna antenna, the more consistent the intake. If the antenna is mounted on top of the house, it should stand at least four feet above the roof itself.

Generally, in the areas of reception edges, a larger antenna will result in better and more consistent income than small. A special directional antenna may be required in areas that are particularly far from the transmission tower. In more urban areas, the Omni-way antenna should work well.
