External aerials are also available for DAB and will significantly improve reception. The aerial and cables need to be well maintained and you need a radio with the option to connect an external aerial. Unlike the other services, all the predictions of DAB coverage are for indoor coverage.

Use the our Transmitter Checker tool to determine the best transmitter for your location. Ensure there is nothing in front of the aerial that could block the signal, such as trees. All TV reception predictions assume an outside aerial at a height of 10m from the ground.
Even the best amplifier will still add some noise to the television signal it is amplifying/boosting that could result in picture break up. A good amplifier should have a filter built in that only allows the signal you want to be boosted and not any unwanted signals. Otherwise, all the unwanted signals will also be boosted, which can cause pictures to break up. Sometimes, a technical glitch can cause the wrong regional news to show up by mistake.
This often sounds like birds tweeting and happens if there is another frequency being transmitted near the one you are listening to. This can commonly be caused by high pressure when, during fine weather, radio signals can travel much further than normal. There is nothing that can be done and the problem will go away when the weather changes. If you live close to a transmitter or can get a strong TV signal, then it could be possible to use an aerial in your loft or an indoor portable aerial.
- If the problem persists when you turn the heating system back on, the problem could be with the thermostat, which may need to be repaired or replaced.
- At that point you will need to tune your radio until you find a signal.
- Most DAB radios come with built in signal strength meters which can be helpful.
- At night medium wave radio signals can travel much further than during the day.
Centimeters to Feet Conversion Made Simple
- Try moving the radio around to see if you can find a better position where you get good reception of all the stations you want to listen to.
- A centimeter is a unit of length in the metric system, equal to one-hundredth of a meter.
- If you suffer from reception problems in the evening, this suggests that the signal getting to your television is not quite strong enough.
- However, if you’re regularly getting the wrong region’s news, it’s possible your TV has tuned into a different transmitter that carries a different regional service.
Other causes of interference to MW or LW radio in the car can include mobile phone chargers and dashcams. Check that connections are secure and cables are not damaged and see if the interference goes away of you move the equipment to other areas in the car. External aerials are also available for FM radio and will significantly improve reception. The aerial and cables need to be well maintained and you will need a radio that has an option to connect an external aerial.
It is important to check your installation is working properly and that your radio is in the best possible location. This can happen when your radio receives more than one signal. The second signal is picked up by the radio moments after the first. For example you receive one signal directly from the transmitter and another is being reflected off a nearby hill.
Radio Reception Help Guides
A radio which can tune to medium and long wave services usually has an aerial built in, which you cannot see. As the aerial is directional, by simply turning the radio you will be able to get the best reception. Use our Transmitter Checker to check the transmitter is not undergoing any work and to see which FM radio services you can receive from your location. For example, some masthead amplifiers are also distribution amplifiers. A signal amplifier should only be used as a last resort when the television signal is weak.
If your radio displays signal strength, use this as a guide to ensure the best position. Freeview television and radio services are broadcast around the UK using a number of multiplexes. Three multiplexes have the main UK channels, which include those from the BBC, ITV, Channel 4 and Channel Five, and are available to 98.5% of households in the UK. Athletic competitions and training regimens often mix unit systems.
YouView is a “hybrid” service that combines the regular, over-the-air Freeview channels, and catch-up TV from those same channels, streamed to you via your broadband connection. You can then scroll back (on selected channels), up to seven days, and watch some of the shows you’ve missed by streaming them via the internet. The availability and number of channels you can watch via Freeview on TV depend on the reception in your area. If you use a Freeview recorder box (more on that below), you can record live programmes for later viewing, or pause and rewind live TV.
This is because the transformer would have been designed to operate at the higher power and not the lower power the LED lights use. The RDS system is set up to detect local radio travel news. The way to turn traffic announcements on and off on varies between radios. The most common FM radio aerial on a portable radio is a telescopic one. To get the best reception extend the aerial fully and move the aerial and radio around until you get the best reception. If using a hi-fi with a wire aerial, again extend as much as possible to get the best signal.
If all other stations are working ok and you have just lost one station. The problem could be due to a number of reasons, the station may have stopped broadcasting or have moved multiplexes rather than a radio fault. All of the stations in one multiplex should be behaving the same way. Radio reception can drop out when on the move due to changes in topography.
How many centimeters in a foot
Next, you might want to consider getting your aerial installation checked. However the CAI (Confederation of Aerial Industries) is a recognised trade body and can put you in touch with one of their members in your area. If you are a tenant or are using a communal aerial, you should contact your landlord/managing agent. Depending on the transmitter you are using, your aerial elements will need to be mounted flat (horizontal) or on its side (vertical).
Use our Transmitter Tool to check you are tuned to the best frequency for your area, as you can often pick up more than one signal. An electric motor is used in many appliances such as electric lawnmowers, washing machines, drills and hairdryers etc. A faulty motor can cause electrical interference. Check any appliance with an electric motor by moving your radio away from it to see whether the sound improves. If you have several appliances with electric motors you may need to turn them all off and try the above one at a time. Many people are now using low power LED lights instead of the more traditional varieties. However, if the original light used a transformer rather than directly running off the mains, it is possible the transformer is causing the interference.
Height Conversion
Attenuators can be used to decrease the incoming signal if it is too strong without distorting it. It is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, boosts the signal, an attenuator provides loss, reduces the signal. Attenuators are always a compromise and should only be used if absolutely necessary. However the CAI (Confederation of Aerial Industries) is a recognised trade body which will be able to put you in touch with one of their members in your area.
It is widely used worldwide in education, construction, tailoring, and science. Centimeter (cm) is a unit of length in the metric system, equal to one hundredth of a meter. Commonly used for measuring human height, object dimensions, and in construction. Centimeters and feet are both units used to measure length. But I mostly use Freeview to browse – and it works great for that. I’m lucky enough to have good reception with an indoor aerial.
Get instant, accurate results with our comprehensive calculator suite. A foot is a unit of length process requirements example in the imperial and US customary systems. It is mainly used in the United States, Canada, and the UK. Our full terms & conditions can be found by clicking here (in English). Try our free downloadable and printable rulers, which include both imperial and metric measurements.
Whether you are measuring the length of a pencil or determining the height of a person, the centimeter is a valuable unit that helps us understand and quantify the world around us. A centimeter is a unit of length in the metric system, specifically the International System of Units (SI). It is equal to one hundredth of a meter, making it a smaller unit of measurement compared to a meter. The centimeter is commonly used for measuring small distances, such as the length of objects or the height of individuals.
This can be greater at different times of the year (when there are more leaves), when wet or in high winds. For programmes which are pre-recorded, we create the subtitles in advance. A technician uses the audio and picture to sync them with what’s happening on screen. For a programme broadcast live, (like the News), subtitles will be generated as it is broadcast, which is a complex and problematic process. This means you’ll often notice a delay when watching live programmes. If you suffer from reception problems in the evening, this suggests that the signal getting to your television is not quite strong enough.
To see whether there are any faults with the local transmitters use our Transmitter Checker tool. This will help you to see if there are, or have been recently, transmitter faults in your local area. Check cables and leads within your property to ensure the problem is not a simple installation fault. Please see our Freeview Installation guide for further details. Try moving the radio around to see if you can find a better position where you get good reception of all the stations you want to listen to. The foot has a long history and has been used as a unit of measurement for thousands of years.
