VHF and UHF

Once you have cut the cord, the next thing that comes to your mind is what options you can select to ensure that there is no interruption in your daily dose of entertainment. Purchasing a TV antenna is considered to be one of the best solution for those who prefer watching local channels absolutely free of cost. All you would need to pay for is the initial antenna cost. However, there are certain factors one should bear in mind before purchasing a TV antenna. One of those factors include, the type of frequencies received whether VHF or UHF.

Basically when you would be purchasing a TV antenna, you would be asked to make a selection between VHF and UHF. Though it may seem tempting and practical to mention both but there is still a need for knowing exactly what are you receiving when you spending so much money on the antenna. Currently there are quite a few number of channels on the VHF frequencies and on the other hand the number of channels on the UHF frequencies is rising. There are also certain TV antennas designed to pick up both type of frequencies VHF as well as UHF.Also in addition there are quite a number of local broadcasting stations which were making use of VHF prior and now going in for UHF signals. One of the reason for the same being, that both the signal frequencies cannot exist together.

VHF refers to TV channel frequencies of the channel numbers that fall between 2 and 13. The signal band of VHF is broken down further into two frequency bands. First being the low band which refers to those channels that fall between 2 and 6. On the other hand the high band refers to those channels that fall between 7 and 13.UHF refers to the signal frequencies for channels which are 14 and above. Before the transition that took place in the year 2009 all of the UHF frequency band was those channels that came between 14 and 69. But the new UHF digital frequency considers channels 14 to 51. However, if you have a tuner in your TV unit then it would still display channels which are above channel number 51. But this would be mostly for recognition reason.

In the United States, there is a need for having a UHF/VHF TV antenna so that you can receive most of the channels that are available in your area with just few exceptions. The TV signal wavelength of VHF are considered to be longer as well as wider than those that are used for the UHF. The TV signal wavelength of UHF are considered to be shorter as well as narrower. Hence the TV antenna that you finally select should be designed in such a way that it should receive all of the various frequency patterns which are used by the nearest TV station especially in your region. At times even when the TV can hardly receive a VHF frequency signal or the UHF frequency signal, they are still referred to as UHF/VHF TV antenna.
