HDTV Outdoor Antenna

The introduction of high definition television (HDTV) around the world has created a market for HDTV accessories, one of which is the HDTV outdoor antenna. Before rushing out to buy a new antenna, it is important to know exactly what it is, how it works, and why it is needed. After the decision to buy one has been made, the difficult task of choosing a model need to be tackled. There are many different models available which can be very confusing for buyers. Thankfully, there are websites that can help with these decisions, along with a color-coded system that makes it easy to find a particular antenna in the stores.

HDTV has been the most significant change to television since the introduction of the first color sets in the 1960s. It has literally changed the way people watch television by widening the picture and improving its quality, not to mention the improvements to the sound quality. But the rapid pace of this change has left many people feeling confused about HDTV and what they need to do to in order to upgrade. This situation has only been made worse by the misleading marketing and high pressure sales tactics that many stores use. Unfortunately, the HDTV outdoor antenna is often one of those accessories that is pushed onto consumers, whether they need one or not.

A HDTV outdoor antenna is simply a regular television antenna that has been changed slightly to improve its reception of HDTV broadcasts. In many cases, a regular antenna can do the same job just as well, but there are some locations far away from the transmitters where the signal strength is not strong enough to use a regular antenna. HDTV is a digital broadcast which does not degrade gradually like an analogue broadcast. It will not display static or other problems as the signal strength drops but will suddenly cut out completely. Locations that previously had fair reception may experience frequent dropouts or have no signal after the change the HDTV.

Installing a new antenna is an expensive exercise so the first step should always be to determine if one is actually required. A HDTV television should be used with the old antenna for a while to see if it suffers from a high number of dropouts. The odd dropout is not a problem and can even occur in locations close to the transmitter. In many cases, the number of dropouts can be reduced by simply adjusting the antenna slightly so that it points more towards the transmitter. If any doubt remains about the need for a HDTV outdoor antenna, a professional installer can come out and measure the signal strength accurately to determine if a new antenna is required.

There are many different brands of HDTV outdoor antenna to choose from, and the most expensive ones are not always the best choice for a particular location. In general, there are two type of antenna and three sizes for each type. For locations that are surrounded by tall trees and buildings, a directional antenna provides the best reception. But for locations free of obstacles, a multi-directional antenna is the preferred choice. A color-coded system is used in many countries to help consumers pick the right antenna. By entering their location into a special website, users can find out the color of a sticker that the most suitable antennas will have on them.

Installing a roof antenna can be a dangerous job and should ideally be done by a professional, but many homeowners choose to save money by doing it themselves. Small antennas can be installed by one person, but the larger and heavier models usually require two people. Remember, installation should never be attempted when there are strong winds or thunder storms in the area. If the transmitter towers cannot be seen from the mast, a compass can be used to point the antenna in their direction, provided that the user knows the bearing to the towers. Instead of a fixed mast, the antenna can also be attached to a motorized rotator unit. These are used for directional antennas that need to be constantly adjusted.
