What are the new dtv frequencies?
Digital transmissions are on the TV channels 2 to 60, this is the VHF and the UHF band. Some stations changed frequencies and added new channels.
What Amateur radio band is 2 meters in... UHF... VF?
The so-called "2 meters" Amateur radio allocation is the band of 144 - 148 MHz in the US. Frequencies from 30 to 300 MHz are tagged 'VHF'. 'VF' typically means 'voice frequency' and is irrelevant to this discussion. "HF" = 3 to 30 MHz. "UHF" = 300 to 3000 MHz.
What is best uhf antenna for tv reception?
Store bought. They have many different varieties. The best come with internal signal amplifiers. You can recognize these easily cause they usually cost more and have to be plugged in to a 120volt outlet. Be sure that the channels you want are all in the UHF band, some HD TV stations are still in the VHF band (2-13). Some additional info, If you can see the transmitting tower from the roof or where your antenna is to be mounted, avoid the powered ones because the signal to the amplifier can be to strong for the it to handle.
If you have a digital tv and an outdoor antennae do you need a converter box?
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
How many channels did the 1960 television set have?
Sets with only VHF tuners had 12, Channels 2 thru 13. In the later 60s a UHF tuner was added giving the set channels 14 thru 69 and some sets had even higher channels.
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.
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.
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 is a digital antenna?
A digital antenna is a device that allows the user to receive digital television signals from varying distances, depending on where they live. There are three main varieties of basic indoor antennas that will allow the user with a strong television signal to receive digital signals. These are the UHF, VHF and combined UHF/VHF. There are other models for homes that receive weaker signals, including those designed for placement outside of the home.
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.
