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. 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.

There are two methods of broadcasting OTA signals-the eight bit vestigial side band modulation technique and the 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 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 other disadvantage of the 8 VSB signal is the fact that it is pretty much unidirectional. The multidirectional performance of 8VSB is poor so you need to invest in a good unidirectional antenna for receiving a good signal. These are available easily in most 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.

The front-to-back ratio of an antenna is another factor important to consider. 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 come with built in HDTV tuners called ATSC. The HD signals can be phased in on some regular and cable channels and a rooftop antenna can receive these.

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. 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. 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.

Furthermore, it’s much preferable to own the best value HDTV for the ideal view. My recommendation for 32 inch HDTV are Samsung 32 inch LED for LED and TCL L32HDF11TA Review for LCD. For less size, I suggest you go to LG LED review.
