You can tell by the length of the usually aluminum dipoles. The dipole length is related to the ability of the antenna to receive the incoming wavelength. Lower VHF television channels require a longer dipole to receive longer electromagnetic wave lengths. Therefore if the dipoles of the antenna are fairly long, say 3-4 ft., you have an antenna for the (lower) VHF wavelengths. If the dipoles are very short (1 ft.) then the antenna is more capable of receiving shorter UHF wavelengths (and most digital signals, too). Many modern television antennas for exterior use combine the capabilities and have different dipoles for both high and low frequency waves. Effective 2/17/2009; all TVs with an antennae will no longer work. You must have a cable box in order to see TV nowadays.

Can a uhf antenna pick up vhf signals as well?
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.
Should you use UHF antenna with digital converter box or VHF?
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
How can you connect an antenna to uhf and vhf to get both uhf and vhf on tv at the same time?
First, you need an antenna that is both uhf and vhf comaptible. Usuaully it will have a pair of rabbit ears (vhf) and a center loop or plate (uhf). Make sure the rabbit ears are completely extended then just re-scan your channels on your digital box or your hdtv.
What's a good antenna for a TV?
Getting a VHF antenna will allow the TV to have a strong signals and get the programs that you would need. Also, UHF could be another alternative to VHF.
What kind antenna you should use with HDTV converted box?
A VHF/UHF antenna is the correct one for HDTV. If you are using a indoor antenna, the amplified ones are better.
When should you use VHF over UHF?
A couple of points: When you're on the receiving end, UHF signals have a few disadvantages over VHF signals, owing to UHF's higher frequencies: 1) UHF transmitters tend to be less powerful than VHF transmitters 2) Transmission lines lose appreciably more signal at UHF than VHF, and that's just for transporting the signal from the transmitter room to the antenna 3) UHF signals tend to get weaker more quickly than VHF signals as they propagate outwards from their transmitters 4) UHF receivers tend to be less sensitive than VHF receivers UHF signals have one particular advantage over VHF signals: The smaller wavelengths of UHF signals allow for a smaller antenna to provide the same performance as a larger VHF antenna. Alternately, you can make the UHF antenna larger for enhanced performance, and it might still be small compared to a nominal VHF antenna. (Please pardon all the vague, qualitative references.) High-performance antennas for UHF that are not especially huge can more-than-compensate for lower power transmitters, lossier transmission lines, higher path-losses, and less sensitive receivers. Another advantage of UHF (and microwave) is that there tend to be more frequencies available than at the lower VHF frequencies. As technology advanced over the years, radio-spectrum habitation moved from the lower frequencies to the higher frequencies. Necessarily, the tendency is for lower, "older" (VHF) frequencies to be more crowded than higher, "newer" (UHF / microwave) frequencies. More than likely, the frequency you operate on will be determined by the radio-communications-licensing authority in your country (i.e., the FCC in the USA). A particular service might have allocations available in more than one band, i.e., VHF and UHF, and then it's up to the Engineering Department to decide which of those legally available frequencies to chose for their system.
What kind of antenna do you need for broadband TV?
Try a regular off air UHF/VHF antenna which cover channels 2 thru 69. while there are a few VHF stations (channels 2-13) still on the air most are UHF (channels 14-69) and are HDTV. This info applies to stations in the USA.
Did old televisions have cable plugs?
No. They had two screws for VHF and two screws for UHF. The screws were for the two wires from each antenna.
Will a plasma TV work with an antenna?
A plasma TV set is just like any other TV set on the market. It can accept video/audio signals from an VHF/UHF antenna if it has an aerial VHF/UHF antenna input. It can also accept DVB-C or DVDB-S or DVB-T through the same antenna input. You have to refer to the manual that came with your plasma TV set to see what types of signals it can receive through its antenna input.
What is communication system of the aircraft?
Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.
Why the upper band of vhf frequency is considered as uhf frequency?
Different people see the boundar between VHF and UHF differently. I tend to regard UHF as starting at 200 Mhz.
Does a dynex 32 HD TV require a digital antenna?
No such thing as a HD antenna. All antennas are the same. Your antenna should be a UHF/VHF type. Many new ones are powered to help get enough signal to the HD set.
