TV antennas are making a comeback. Due to technical changes and advances in HDTVs, more and more people are looking to buy antennas. These are mainly required to receive OTA or over-the-air-digital signals and for this purpose, you may need over-the-roof antennas. Antennas are also necessary when you have a satellite service but need local channels.
Today you can purchase state of the art TV top antennas too, but they are expensive and cost over hundred dollars. Even the rooftop antennas have gone changes in designs. 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. Both these systems have their pros and cons. For the sake of this guide we will speak only of the 8 bit VSB broadcast as it utilizes the spectrum efficiently as a result of which the US government has standardized this for all 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 consideration when choosing antennas for your HDTV is the distance from the broadcasting stations; if you live more than 10 miles away then adequate reception can be had using roof top or attic mounted antennas. On the contrary, the indoor antennas are sufficient for distances less than 10 miles. The other disadvantage of the 8 VSB signal is the fact that it is pretty much unidirectional. Hence you need to invest in good unidirectional UHF antenna. Such antennas are easily available in the electronic stores. If you live more than 15 miles from the broadcast station then you need to place the antenna at the highest point on your roof.
Another important factor you must not ignore when you purchase antennas for HDTV is the front-to-back ratio of the antenna. Larger this ratio, lesser is the interference in signal and better the picture quality. If you are living in an area with very tall buildings, then signal interference is a major issue; a highly directive antenna with a good front-to-back ratio can help your signal reception greatly.
HDTVs come with HDTV receivers. Some TVs also have ATSC tuners that are built-in. The High def signals can be tuned to be received on regular/cable channels and a good rooftop antenna can receive this.
For getting the best HDTV signal reception, you need to use high aperiodic antennas that can be practically mounted on the rooftops or attics. You should alos note that any poor-quality signals and dropped signals are usually due to antenna issues. In fact, many electronic stores have maps provided by surveyors which indicate which antenna type is best suited for your area of residence. So you can talk to customer reps regarding the choice of an antenna. The price of antennas usually lies in the range of $80 to $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.

Apart from the antenna, make sure you own good-value HDTV. Here's two of my top recommendation: TCL L32HDF11TA Review for LCD and UN32D6000 review for 32 inch LED.
