From what I have researched and discovered your normal antenna that you have should suffice in picking up the digital signal. Mine at home is working fine with it. Just be careful because the stores are going to try and say you need to get a new antenna when in reality there is not a single difference in design or material or calibration of any sort. That person has not had trouble so far because it has not switched to strictly digital yet.

What are the advantage of Yagi-uda array?
The Yagi array allows a significant increase in antenna gain (expressed in dBi or Db over isotropic) by the simple addition of parasitic elements to a dipole or folded dipole.
What is the difference between yagi antenna and dipole antenna?
I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.
What are the advantage of trap dipole antenna?
A dipole antenna, is a radio antenna that can be made of a simple wire, with a center-fed driven element. It consists of two metal conductors of rod or wire, oriented parallel and collinear with each other (in line with each other), with a small space between them. The radio frequency voltage is applied to the antenna at the center, between the two conductors. These antennas are the simplest practical antennas from a theoretical point of view. They are used alone as antennas, notably in traditional "rabbit ears" television antennas, and as the driven element in many other types of antennas, such as the Yagi. Dipole antennas were invented by German physicist Heinrich Hertz around 1886 in his pioneering experiments with radio waves.
Does a digital TV have a built in antenna or tuner that will pick up over the air signals without an outdoor antenna?
I have not seen any digital TVs with a built in antenna. Depending on where you live you could use a simple "rabbit ears" setup or even one with a built in amplifier if you're a bit far from the stations.
What type of antenna used in rfid?
All types... depending on frequency and application. Lower frequency RFID's are typically near field and use inductive antenna designs, higher frequency ones use far-field designs. Low frequency RFID's like the TIRIS pet ID's use coils of wound wire. HF type RFID's like MiFARE use simple planar loop antenna designs. Most VHF RFID's use dipole and modified dipole designs with reflector elements. UHF and microwave RFID's frequently use patch and slot antenna designs.
How do you use the word antenna in a sentence?
Its simple, The antenna of the T.V was broken and could not be fixed so a new antenna had to be bought
How do you build a simple home use antenna?
== == For digital TV, you can build a DB4 antenna out of wire coat hangers and a piece of wood. Very simple to make. There are step by step instructions here - www.TheTutorGenie.com/DigitalAntenna.html - It works great. It depends on what you want to do with it. A receiving antenna for 40 m shortwave could be just a long piece of wire tacked to the walls. An antenna to transmit and receive at 440 MHz is a completely different animal. Here's a fun web site: http://www.ac6v.com/antprojects.htm
How to make a homemade FM radio antenna?
The cost of repairing drywall damage would depend on how much damage is done. If you were to buy the drywall it ranges from $10 to $30 a sheet. Plus if you hired someone then it would cost more for labor then it would if you did it yourself.
Does an ungrounded antenna near the ground act like a single antenna with twice the height?
A better simple approximation would be two antennas separated by twice the distance of the single antenna to the ground.
Advantage and disadvantage of using antenna?
Advantages of Antenna:- -They are cheap and exhibit good gain. -It delivers good performance with a size less than a dipole antenna. -They are cheap and not simply de-tuned by hand movements. -The size is less than the whip antenna. It can be used for wideband applications. -It is a very directive antenna and provides a good amount of gain. -They are very simple and a bit antenna. They are practiced in smartphones due to their thin structure. -They are very small in size and are less affected due to environmental factors. They are separate components. -They are simple in design and are poorer in size. They are robust in nature. Disadvantages of Antenna:- -They exhibit a large size at a lower frequency. -The higher cost is a major disadvantage. A better ground plane is needed to achieve good performance. -They have poor addition, difficult to tune and are very narrowband. -The major problem of this type of antenna is difficulty in feeding it. -They are bulky in size. They are de-tuned by nearby objects very easily. -They are larger in size at a lower frequency and hence it is difficult to design them for frequencies less than 433 MHz.
What is radiation pattern for an antenna?
Radiation pattern is just a map of how the strength of the signal varies around (transmitting) antennas. For some, like a simple whip antenna, the patttern too is quite simple. For directional antennas they can be quite complicated.
What is dipole movement?
The correct spelling is dipole moment instead of dipole movement. The definition of dipole moment is the net molecular polarity measure. It is the separation of dipole ends and the magnitude of charges.
