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 happened to channel 7.1 digital broadcast?
They changed back to VHF which means the bunny ears. So use Bunny ears to get channels 7.1-13.1
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.
In US what is the safety and distress calling frequency?
VHF Chanel 16
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 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.
Which frequencies are the airband frequencies?
Airband, a group of frequencies in the VHF radio spectrum, uses the frequencies between 108 and 137 megahertz. A license is required to operate airband equipment.
Will the new digital signals be in both UHF and VHF?
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
Harris vhf radio can communicate with prc77 radio?
The PRC77 radio operates on 30.000 to 75.95 MHz. If the Harris radio operates on any of the same frequencies (I know you said it's VHF, but VHF covers 30 to 300 MHz), then it can.
Is there software that can pick up UHF and VHF frequencies?
yes and also this can cause a virus n your hardware
What does vhf stand for?
VHF = "Very High Frequency" Formally, radio frequencies from 30 MHz to 300 MHz. (Wavelengths between 1 meter and 10 meters)
Is digital tv on both the uhf and vhf spectrum as was analog tv?
Yes
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.
Why vhf is used for tv signals?
Hi, VHF was used because primarily, that was the highest frequencies that transmitters could be manufactured for at the time TV came into existence. Since then, technoligies have improved and we've gone way, way beyond the limitations of VHF. The interesting thing is that as of February 17, 2009, ALL of the VHF TV transmitters will have been shut off (By order of Congress) and TV will have moved as an industry into all digital transmissions and HDTV. If you have an older set that's not digital ready, it'll no longer receive anything off the air. On the same token if you have a cable or satellite box currently working on your TV, you shouldn't experience any change in services. Hope this helps, Cubby
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.
Why are TV broadcasts in the VHF range easier to receive in areas of marginal reception than broadcasts in the UHF range?
Signals in the VHF frequencies have a tendency to follow the curve of the earth and bend around hills where UHF tends to travel more in a straight line.
