Advice 1: How to choose the aerial filter

Splitters used to connect one antenna to several TV differ from each other in a number of settings. When selecting such a device should be guided by the frequencies of received channels, number of televisions, the thickness of the cable and even the skills of the installer.
How to choose the aerial filter
Instruction
1
If your TV can show through the menu the frequency channels, find out these details about all the programmes that you take. Find the channel with the highest frequency. Choosing a splitter, make sure the upper boundary of the range has more of this frequency. If no TV function display frequency is useful to have friends in the time machine with that capability.
2
The number of outputs of the splitter must exceed the number of existing TVs. If some of the rooms you have TV receivers do not exist, it is useful to take a device that can "grow" with additional outputs. Over time, you may acquire and TVs these rooms.
3
Note this parameter as damping. It is expressed in decibels. Its value is specified on the housing of the splitter or in the instructions. The smaller it is, the better.
4
Decide beforehand how and where you will be installing the splitter. It is highly desirable to mount it on a wall, and not leave hold on some cables - and more reliable, and prettier. In this case, the device must have the fastening holes. If the device will be placed in a prominent place, it must have aesthetic appearance. In case, if you are going to install a splitter inside wide cable box, it needs to have minimum dimensions.
5
Connection method device choose in accordance with the types of cable used, and have soldering skills. Splitter with screw terminals compatible with cables of any diameters, and soldering is not required. Won't need it for installation device with screw connectors, but the cables you can connect just fine. In the presence of soldering skills buy a splitter designed to connect in this way. Finally, the device is equipped with coaxial jacks (like on TV), you can connect to any cables, using a regular antenna plugs. Themselves plugs purchase in the same store, and the type they select, depending on the availability of skill of soldering (some of them allow you to attach the cable with the screws).
6
Don't be confused when buying a splitter with another device similar purpose: unifier or divider signals of different ranges. Some older TVs have separate antenna inputs for VHF and UHF range. With such a device will have to place the delimiter signals that allows you to connect both inputs to one antenna cable.
Note
Before connecting unplug all the TVs and any other connected signal sources.

Advice 2 : How to choose aerial cable

In order to choose the right antenna cable, you need to examine its Datasheet, as well as insulation and sheath. You must pay attention to the life, resistance and attenuation.
How to choose aerial cable
You will need
  • A piece of cable marking, its technical passport.
Instruction
1
Carefully read the label of the cable. It is important that its core was made of copper or copper-plated steel. Due to this, the cable will have a rigidity and good performance.
2
Examine the outer insulation of the cable. It should be solid and inelastic. Slide your fingernail in isolation. If separating the pieces of material, such cable should not be used for the spacers between the TV and the antenna.
3
Remove the top layer of insulation and check the tightness of the braid screen of the Central core. The more thin wires in the braid, the tighter the screen the less interference with his work.
4
Note the nameplate data cable. The lower the value of attenuation of the TV signal at a specific frequency and cable length, the better the television broadcasts.
Note
For antenna use a cable with impedance of 75 Ohm. When the resistance is below this figure the cable can only be used for radio transmission equipment and computer networks. At resistance values higher than 75 Ohm cable suitable for matching of the receiving antenna with a feeder.
Signal attenuation 70% means that the service life of the cable expired. When choosing a product, pay attention to this data sheet, which contains information about the life of the cable.

Thin cable is not suitable for antennas. It can only transfer a limited number of channels and shielding his meager opportunities.
Cable RK-75 is obsolete, it is of high attenuation.
Buy the cable only in specialized stores.
Useful advice
TV always has a circular shape. Cable operating in the bands UHF and SHF, preferably using braid and foil, as well as tubular polyethylene or PVC insulation waterproof gel filler. This will improve operating conditions and reduce the level of interference on TV signal.

Advice 3 : How to connect a antenna splitter

A second and even a third TV in the house - not a luxury but an integral part of a comfortable life. But in order to enjoy it fully, you must properly connect the antenna splitter.
How to connect a antenna splitter
You will need
  • - antenna splitter;
  • cable television;
  • - plugs;
  • - the knife.
Instruction
1
Select the location where you plan to install the antenna splitter. Mark the future location of the splitter and your TV receivers.
2
Take your measuring tape and measure the distance to each of the TVs that will connect. Write down the result. Add the results of the measurements. You got the total length of the cable. Add to this number a couple of meters for insurance.
3
Buy the right amount of cable and all necessary cable, connectors (number of TVs), mounting brackets (if you are going to mount the cable to the wall). When buying check that the inner diameter of the nut splitter with an external diameter of the cable.
4
Cut the cable into pieces according to your size. With a sharp knife remove the outer sheath from end of cable. Foil shield and braid separate from the center and fold the brown piece of cable. Be careful not to accidentally cut them. Also free from the isolation of the Central part of the cable.
5
Put on end of the cable nut splitter. Peel back the screen braid. Insert the copper core of the cable into the slot of the splitter and tighten the nut. Repeat these steps with the remaining segments of the cable. Secure the splitter to the selected location.
6
Move each piece of the cable to the TV, for which it was intended. If necessary, secure it with the staples purchased or put in the cable duct baseboard.
7
Install on the free end of the cable plug. To do this, prepare the cable as described above. Replace cap plug. Peel back the screen braid. Insert the Central wire into the hole of the plug and secure with screw. Braid crimp around the cable sheath bandage. Screw the cap onto the housing. Insert the plug into the antenna socket of the TV.
8
Turn on all the TV sets to assess the quality of reception. If it does not meet your requirements, you need to install the antenna amplifier.
Useful advice
Instead of a knife you can use a special cutter for the cable.

Advice 4 : How to connect antenna plug

To make a high-quality television signal, you must connect your TV antenna to the TV. Connect the cable with the television receiver by using a special antenna plug.
How to connect antenna plug
You will need
  • cutters;
  • knife;
  • - The F-connector.
Instruction
1
Obtain and organize the tools and connectors for connection to a television receiver. Using long-nose pliers, align the edge of the cable. Observing the precautions, carefully cut the outer 15 mm of the cable insulation. Do not damage the wires between the inner and outer insulation. Carefully turn them back, then remove the foil around the insulation of the inner part of the cable.
2
Also carefully remove 10 mm of insulation around the inner core of the cable. Make sure that the many cores of the windings not touched her, otherwise the signal quality will deteriorate significantly.
3
Purchase in any store of electronics F-connector. Unscrew it. Insert the prepared cable into the connector, called "dad." The outer coil thus pressed against the housing F connector. Internal lived fall in the protruding part and will look out about 3 millimeters. If lived will interfere, it can bend. Clamp the cable clamping ring. Connect the connector to the antenna Jack of the TV.
4
You can also purchase a plug with fixing cable by means of soldering. In this case, use a soldering iron and solder. Observe measures of fire safety. You get it in a well ventilated area. Hot soldering iron, use a special non-combustible stand. Do not leave the soldering iron plugged in, on the table.
5
Prepare the cable as described above. The outer shell collect in the form of a beam with one hand. Carefully solder the inner conductor to the Central part of the connector and the coil twisted together, to the exterior. Check out the places spikes on the availability of the circuit. Eliminate them if necessary. Wear insulated bezel and connect the plug to the TV.

Advice 5 : How to choose the antenna amplifier

In zones of uncertain reception of a television signal users have to take measures to improve the quality of sound and image on their own. One possible solution to this problem may be the antenna amplifier. In terms of DXing such a device in most cases leads to a significant improvement in image quality. When selecting the antenna amplifier, it is important to have an idea about its features and principle of operation.
How to choose the antenna amplifier
Instruction
1
For reliable reception of a television signal amplifier must assume the installation at a distance, as close as possible to the receiving antenna. This power must be supplied via a coaxial feeder cable through the appropriate junction.
2
Make sure the antenna amplifier has the ability to connect the adapter (power pack) power up to 10 watts. This is especially important when connecting the amplifier to the television receivers imported.
3
Note the gain of the device. With an average cable length of 25 m, taking into account possible losses and signal attenuation should select a device with gain of 25-35 dB. If the gain is too large, and the antenna is poorly aligned with the cable, on the screen of the receiver will be just a blur.
4
Find out what the noise antenna amplifier. This feature needs to be significantly below the noise of a television receiver.
5
To receive broadcasting in the meter range select the antenna amplifier of the type UCDI-1, designed for 12 channels. It has built-in power supply for 220 V. the gain of the signal device is at least 12 dB.
6
When using receivers that provide broadcasting in the UHF band, use special amplifier UHF. You need to install it directly on the mast of the TV antenna. Having a gain of 14 dB, this device can surely amplify the signals of 20-40 channels.
7
One of the parameters relevant for signal amplification, is the diameter of the cable insulation. If the length of the feeder reduce the substantial use when connecting the booster cable with the largest diameter of the insulation. Antenna amplifier allows you to use feeders great length that in the absence of the amplifier would lead to a weakening of the signal to the level necessary to make a high-quality signal.
