Those of you who thought that TV antennas have become obsolete, think again. Due to advances in technology and government rules, antennas have become indispensable. Over- the- roof antennas are required for the OTA or over the air digital signals. Antennas are also necessary when you have a satellite service but need local channels.
Set-top antennas today, provide cutting edge designs-but they can also set you back by hundreds of dollars. The older rooftop antennas have also undergone a tremendous change. No longer are the antennas, monster-like and scary; you get many compact designs that fit easily under awnings and in the eaves of roofs. These antennas can also be amplified to boost signal receptions.
Over the air or OTA signals can be broadcast in two ways: the 8 bit vestigial sideband modulation and the other is Coded Orthogonal Frequency Division Multiplexing. Each of these systems has pros and cons. The 8 VSB utilizes the broadcasting spectrum more efficiently so the US laws have made this as the broadcast standard for US digital TVs. The drawback of this system is that it is difficult to receive the signals, hence antennas are becoming even more of a necessity.
An important factor while considering antennas for your HDTV are the distance of your home from the broadcast station; for distances over 10 miles, you need attic mounted or rooftop antennas. On the other hand, if the broadcasting station is not too far, then indoor antennas can suffice. The second drawback of US 8VSB broadcast is that its multidirectional performance is quite poor. The multidirectional performance of 8VSB is poor so you need to invest in a good unidirectional antenna for receiving a good signal. Such antennas are easily available in the electronic stores. Do remember to place the antenna at the highest point on your roof if you live more than 15 miles from the broadcasting station.
The front-to-back ratio of an antenna is another factor important to consider. This directly translates to the fact that higher the ratio, better is the signal quality received by the antenna. That said, a highly directive antenna is an absolute necessity in an area with tall, interfering buildings, as it offers a large front-to-back ratio which can prevent this interference.
When you purchase a HDTV you also get a HDTV receiver. Some TVs also have ATSC tuners that are built-in. The HD signals can be phased in on some regular and cable channels and a rooftop antenna can receive these.
Experts recommend that best signals reception for HDTVs can be obtained using rooftop based aperiodic antennas. If you are receiving dropped signals then chances are that the issue is related to antennas. Many electronic stores carry color coded maps to direct customers as to which antenna is best suited for the area they live in. So you can talk to customer reps regarding the choice of an antenna. Most antenna prices cost from $80 to a little over $100. If you are wary of rooftop installation, you can go in for a dealer who sells the antenna and also gives free installation with it.

Besides the antenna, be sure to own good-value HDTV. Here's 2 of my top recommendation: L32HDF11TA Review for LCD and UN32D6000 review for 32 inch LED.
