Hi there!

Assuming that you tried to tune stations onto the UHF bandwidth and received nothing,Commonly the tuner box is probably at fault and needs replacement. The VHF and UHF signals are split inside the tuner so if you receive VHF fine then UHF should as well unless faulty of course. Some circuits require an external IC to do the switching, but more on the older models. Regards and good luck, JUS004

What does RF CH mean?


What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

I bought HDTV/UHF/VHF/FM INDOOR PASSIVE ANTENNA please help me to install it it is not working


Is the antenna the correct one for your environment? Do you have the antenna pointed at the stations you want to receive? Use antennaweb.org or tvfool.com to get an idea of the location and likely channels you can receive at your location. Antennaweb assumes an outdoor antenna but is very conservative in the list of channels you can receive. (These may match the limits of the indoor antenna.) TVfool lists the stations and the appropriate antenna that will likely receive each station.

Tall trees and buildings will block the signal. Get the antenna as high as possible. Move the rabbit ears and UHF loop to maximize your signal strength. Then make sure the TV is set to use the OTA tuner (ATSC for digtal stations). (That may mean changing the source in the setup menu.)

Then scan for channels. Move your antenna or parts of it and rescan or edit the channel list. (For some TVs there is a weak signal setup option that will let you manually enter the station number (including sub-channel). Then it will provide the signal strength information as you move your antenna.)

I hope this helps. An amplifier may help you bring in weak stations with enough signal strength for the tv to see them.

I have tried two different antennas and the screen says that the signal is weak I bought the TV today


If you're using an indoor antenna (rabbit ears), you'll find that there's little difference between them. Yes, you'll see all the fancy knobs, but mostly all they do is delay the signal from making it to your antenna jack, hopefully enough to reduce ghosting on analog channels...or a resistor circuit that reduces the signal strength. Receiving a good signal with an indoor antenna can be difficult...there can be obstacles between your tv and the broadcasting station, you could be too far away...it's hard to tell. Before you use an outdoor antenna (consider a good RV antenna if you need to use it indoors), try an antenna amplifier. It'll have to handle both VHF (at one time channels 2-13) and UHF (channels 14-69 analog). If it's an "antenna amplifier," it will be sufficient. If it's a cable amp, it would be a hit-or miss. The amp may be able to boost your signal with the indoor antenna you have now. Alternately, you can buy an indoor antenna with the amp built in. Hope this helps.

DO I NEED A DIGITAL CONVERTER TO OPERATE A 4 YEAR OLD JVC MODEL AV-32D305 WITH AN ANTENNA?


If you have cable running to your house, cable still uses RF and older TVs work fine. The problem comes when you try to grab stations from the air. The signal is still UHF, but the information riding on that UHF signal is digital, and will need a converter box to turn it back to analog so your older TV will understand it. . Cable: None needed. . Antenna: Need a box.

Use an Antenna that Provides Good Reception of All Channels
  • Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
  • For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
  • Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
  • The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
  • Many antennas currently being sold as “HDTV Antennas,” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Check Your Connections
  • Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
  • Ensure that your components are plugged in and have their power turned on.
  • If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
Perform a Channel Scan
  • Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu. Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
  • Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
Adjust Your Antenna
  • Small adjustments to your antenna can make a big difference in the number of digital channels you can receive. If you have an indoor antenna, try elevating it and moving it closer to an exterior wall of your home. After adjusting your antenna, perform another channel scan to see if your reception is improved.
  • While adjusting your antenna, it may be helpful to access the “signal strength meter” on your digital-to-analog converter box or digital television to determine whether your adjustments are improving the signals’ strength. The signal strength meter is usually accessed through the menu feature on your remote control. Refer to the owner’s manual of your device for detailed instructions on how to access its signal strength meter. Remember to do another channel scan after you have adjusted your antenna.
  • Television stations broadcasting in digital use both the VHF band (channels 2-13) and UHF band (channels 14-51). Many indoor antennas use “rabbit ears” for the VHF band and a “loop” or “bow-tie” antenna for the UHF band. Make sure you are using an antenna that covers both the VHF and UHF bands and have connected it properly.
If You are Still Having Difficulty:
  • Until June 12, 2009, some stations will be operating at reduced power levels. If you are not receiving certain digital TV stations, this does not necessarily mean there is a problem with your antenna or digital-to-analog converter box or digital television. Check with the TV station to find out whether they are planning changes that will improve reception.
  • When an analog TV signal is weak or receives interference, static, snow, and distortion will often appear on the screen. Digital broadcasting will provide a clear picture; however, if the signal falls below a certain minimum strength, the picture can disappear. This “cliff effect” means that if you watch analog TV stations that have static and distortion, you may have to adjust or upgrade your antenna system.
  • Simple indoor antennas provide minimal performance that may not be suitable for your location. If you are unable to obtain satisfactory DTV reception with your current indoor antenna, you may wish to obtain an indoor antenna that includes features for better reception of UHF signals, as well as VHF, and/or an amplifier to boost the received signal (often referred to as an active indoor antenna).
  • Generally, an outdoor antenna will get better reception than an indoor antenna. However, the performance of outdoor antennas can degrade over time due to exposure to the weather. If you are having problems, check for loose or corroded wiring, broken antenna elements and that the antenna is pointed in the right direction.
  • Try to keep the length of wire between your antenna and digital-to-analog converter box or digital television as short as possible for best reception.
  • “Splitters” that are used to connect a single antenna to multiple digital-to-analog converter boxes or digital televisions reduce the amount of signal available to each device. If you are having problems, check whether reception is improved without the splitter. In some cases an “active” splitter that includes an amplifier can solve the problem.
  • If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” Consider using an “attenuator” or removing amplifiers to improve your reception.
  • If you decide to replace or upgrade your indoor or outdoor antenna, many types are available from electronics retail stores at a variety of prices. Websites such as www.antennaweb.org provide information on the locations of broadcast towers and the types of outdoor antennas appropriate for the stations you wish to receive. If you need assistance with upgrading your antenna system, check with a local antenna retailer or antenna installer.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Hope it may helps:

Digital channels


It's possible the stations you have in your area

have switched from UHF to VHF or vise-versa

I had the same problem and have lost one channel completely

You didn't clarify if your using an antenna or

cable qam so I assumed you are using antenna.

Youll need to check your antenna to see if it

supports both UHF vhf if it only supports one

that could be your problem .

go to antennaweb.org it will help you determine

what stations are avalible to you .

Insignia digital tv converter/indoor antenna no signal


Ok first I can save you some money. Take your "HDTV" antenna back. There is nothing different about the antennas needed receive analog and digital signals. If you got reception without your converter box, use the same antenna with your converter box.

Next let's see if there is a problem with the box. Hook up a television with the antenna. How many stations do you get? Now hook up the same television & antenna, but this time put the converter box between the antenna & the TV. Do not turn on the box. Now how many stations do you get? If the number is different, the box is not allowing the antenna signal to pass through. That is bad. You want your signal to pass through the box so you can still pick up stations that don't broadcast digitally. Some areas of the country will not be covered by digital stations from all major broadcasters when the changeover happens in Feb.

My suspicion is either you did not have the antenna hooked up to the converter box when you searched for channels OR you are in an area that is not yet broadcasting digitally.

I hope this helps you solve your problem. Thank you for using FixYa and feel free to add more questions here by using comments.

Indoor antenna problems


I don't know the menu system on your model, but you have to check that the tuner is in the proper mode. Also, some of the new TV set models cannot receive a standard analog TV signal from its tuner.

As for the distance from the transmitter sight, this depends mostly on the antenna quality, antenna location, the power output of the transmitter sight, compatiblity of the TV to the received signal, and also the capability of the TV's tuner.

Modern TV sets are really designed to be used with a satellite or cable TV box with their respective service.

Terrestrial TV is dying out, and in a matter of a number of years, it will be gone.

Digital signal conversion


If you have cable TV, satellite TV, or FIOS, the coupon eligible converter boxes aren't needed and aren't useful with those services.
They gov't coupon converter boxes are only good for reception with a regular TV antenna or rabbit ears.

According to the specs on epinions.com, no, this TV does not have a digital tuner. So, if you use a rooftop TV antenna (not satellite dish) or an indoor TV antenna, you WILL need an ATSC to NTSC converter box. You need not wait until next year, however, as most U.S. TV stations are also broadcasting digital (ATSC) now.
