Note the location of the antenna. An important role in the reception of the signal plays and the height at which the antenna is located. It does not matter whether it is radio or television. To enhance the indoor antenna, place it as high as possible. If the telescopic antenna for best signal reception it should be fully disclosed.
See where a directional antenna. If between it and the signal source there are obstacles, of course, reception will be poor. Try to place the antenna so that her path was not a large tree, tall buildings, power lines or any other design, can seriously interfere with the signal reception. Thus you can strengthen the antenna.
Use the booster antenna to make the antenna more powerful. This is a special device, which makes the signal reception. Also try to use an additional ground wire. The power to the antenna this will not change, but the signal will be clearer. Any antenna is an open oscillating circuit. The larger the area of a contour, the greater ability of the signal reception it has. The antenna can be any long wire. Clip it to your indoor antenna. This will increase its area, and hence power.
Use last resort, if none of the above methods did not help. Replace the indoor antenna outside. External antenna is much better suited to high-quality signal reception, especially as there is a lot more options to configure. Point the external antenna in an optimum signal receiving direction. This will save you from the need to constantly adjust it, as it often happens in the case of operating an indoor antenna.
Advice 2 : How to improve the image quality of the TV
After buying a new TV after a while often have a feeling that the picture he has some kind of "different". And if the exact configuration of the channels and cleaning the screen from dust positive effect is not given, the output is only one – the parameters of the imageset in the store for your viewing environment of TV programs are not suitable. Let's look at a few professional steps "unprofessional" basic settings image at home.
You will need
- To setup you need a working remote control, user manual, DVD player and DVDs with high-quality recordings of several widescreen films, so when playing from top to bottom of the image were dark bands). You can do without the player, and setting to carry on one of the TV channels, but it is not very convenient.
Connect the player to your TV, start watching the movie and menu settings.
Adjust the brightness of the image. This is done as follows. A pause in the playback at the frame with about an equal amount of dark and light areas. Increase brightness to maximum and gradually lower it until the strip at the top and bottom will not become black. If individual parts in the frame have become thus indistinguishable, then add a bit of brightness.
Adjust the contrast. The setting is done on the image with a white object and visible dark parts (snow and trees, crevasses, etc.). Increase the contrast to maximum. Then begin to gradually reduce it. Lock level when dark details will become blurred, and slaborazvitym. Then start to increase the level to obtain a normal image.
Adjust the color saturation (chroma). Best setting to produce a frame with a human face. Increase the saturation to get "superzagar" face, and then reduce to natural colors, no redness in the wrong places.
The tint setting color and sharpness. The most appropriate parameters 50 (color) and 0 (sharpness). Change only if clearly needed.
Be careful with the settings of brightness and contrast, higher values of realism to the picture is not added, the lifetime TV will not increase, but the sight to spoil you can.
As TV viewing happens mostly in the evening before to carry out manipulations with the image settings, select the room appropriate lighting mode. And for day use preset modes (normal, vivid, standard, etc.) that are made by the manufacturer.
Advice 3 : How to increase antenna signal
To improve the quality of the received image and to catch previously inaccessible channels, do not have to buy a new powerful antenna. The receiving ability of the antenna depends on various external factors, from shape and structure, changing which can adjust the image quality.
The quality of the television signal depends on the location of the antenna. Concrete walls, metal fences and structures hamper the signal, so it's often a outside the house, on the wall or the roof. If you know where is the nearest transmission tower, the antenna should be deployed in her direction.
In General, the setup often requires a certain amount of time and effort. Need to move and twist the antenna, while continuously monitoring the image quality.
You can use two or more antennas to receive a clearer signal. They are located as high as possible, at the same distance from the switch.
Change the design of the antenna
Almost any antenna can be connected to dedicated TV signal amplifier. It works on 220V, to buy booster can in most electronics stores. For a correct choice it is important to know some parameters: the noise factor (it needs to be as low as possible, preferably less than 2 dB), the gain Ku (calculated on the basis of the presence of branching of the cable and its length).
Most often the antenna design is thought through, given standard air. You can edit it by using any metal object, a conductive current: wire, cable, balcony dryers, radiators, etc. are best suited aluminum and copper objects with a large surface area. Metal objects are not in contact with the antenna, by contrast, interrupt the signal.
Some antennas require a special configuration before use. You should verify that the correct frequency range on display to make a particular signal.
The effect of common-mode grille
If you take several identical antennas and spread them horizontally and vertically so that the phase of the signal was in one and the same, it is possible to achieve significant amplification. For example, if a single antenna gives the ratio of 7 dB, the double — up to 10 dB, consisting of four parts — up to 12 dB, etc.
Basic rules-phase lattice parts can be purchased or made their own, but not necessarily the same. It's important to "floors" and "rows" was completely symmetrical, with equal length lines, cable jumpers. Used for fixing frames made of insulating materials, such as wood or plastic.
