You will need
- - USB input.
But this situation can be easily found out. Enough to buy a laptop relatively inexpensive device and you can assume that your family has added a third TV. Such a device is called an external USB tuner. As the name implies, the laptop it connects via a USB socket. The amount of such tuners are often slightly more flash storage. How to connect and configure the tuner? Consider the example model BeholdTV Wander.
Despite its small size, this tuner is very good performance. It can accept both analog and digital signal. There is also a standard for these devices support a radio. The tuner is equipped with a system GIAI (Galvanic Isolated Antenna Input) protects antenna input from the damage of his shock. This usually happens when you connect the antenna cable to the ungrounded computer.
Connect the tuner to the laptop, preferably via USB adapter. Hard antenna cable will tend to "turn out" the tuner out of the slot, which obviously will not contribute to his health. Included with the device is a CD-ROM on which the software is BeholdTV, MPEG codecs from InterVideo, universal DVD player from the same company.
Installing the driver for the tuner is not at all fast. Turn on the tuner in the slot. Next, the system recognizes the device and prompts you to do certain actions. Unable to agree, and you can use the standard installer to Behold.
The default settings of the program BeholdTV made so that using a simple view you with most settings are unlikely to ever encounter, but a knowledgeable consumer will be offered an additional list of features. Hopeless situations, as a rule, does not happen. You can always find some way that will satisfy all conflicting parties.
Advice 2: How to connect the antenna to the TV
Digital image transmission has many advantages over analog devices, but has its own characteristics. The fact that a coded image of a normal analog TV will not accept. Therefore the antenna to a normal TV to this method of broadcasting will have to connect via set-top box decoder.
You will need
- TV antenna, decoder
Connect the antenna to the decoder. Typically used to receive the UHF signal antenna should be inserted into the slot on the rear panel of the decoder. Depending on the model of the device socket will be marked "Antenna" or "Ant".
If the same antenna you plan to use for broadcasting normal (analog) TV, connect using a special cable or antenna extension cable connector on rear panel Ant. out." ("Ant. out") to the antenna input of a television receiver. In the absence of the decoder such possibility of connection, use the divider signal (antenna splitter).
The next step is the connection of the decoder to the TV. The connection can be made at a low frequency using a special interface or a high frequency.
In any interface, first switch the television receiver to the corresponding video mode that the signal did not come from antenna input and relevant video input. To switch use the button on the remote control of the TV or on the front panel of the device. Usually it is denoted by "Video", "AV", "AV/TV", etc.
If your TV has multiple inputs, repeatedly press the appropriate button or select the desired mode from the menu, following the instructions to the TV.
Connect the decoder to the TV at a low frequency trigger via cable with three connectors ("tulips"). Turn one end of the cable into the decoder, the color of plug should match color of socket. The second end of the cable turn on the TV.
Connect the decoder to the power supply. If no indication check in what position is the switch on the body of the decoder (on the rear panel near the power cord). With proper decoder on the front panel you will see the corresponding indication.
Now the antenna is connected through the decoder. Configure the connection, switch your TV to the appropriate video mode. Setup can be done from the control panel via the context menu or buttons on the control panel of a television receiver.
Advice 3: How to make a antenna for the radio
To the radio steadily caught the distant station, need a quality outdoor antenna. It is easy to do yourself, with a couple hours of free time and using very simple tools and materials.
You will need
- - copper wire in varnish isolation in diameter 0.3-0.5 mm;
- - drill;
- - soldering iron.
Select a location for the outdoor antenna. If you live in a private home, the best option would be to install it on the ridge of the roof. To do this the two sides of the ridge hook strong rails with a height of about two feet and attach them on porcelain insulators. The aerial is stretched between the insulators, from her room to the radiowill go from the wire reduction.
Alternatively, one end of the antenna can be mounted on wood, always using the insulator, the second – on the roof or on the frame of the window. If you live in an apartment building and you have no possibility to put the antenna on the roof or give her to a tree, we should fix it in the house, the contour of the window frame. But the efficiency of this antenna is lower than the outer.
For the manufacture of antenna you need wire in varnish isolation in diameter 0.3-0.5 mm. From it using a drill you have to twist the antenna wire for this first 20-30 times route the cable to the desired length (e.g., 10 meters), clinging to the nails or wire hooks. Then remove the wires from one of the hooks, hold the drill tight and weave for stranded wire.
In the place where the antenna will be to move the wire reduction, a little rasplatita cord, scrape all the strands into a length of 2-3 cm attach them stripped wire reduction and carefully propagte. Strengthen the finished antenna on insulators and remove the wire reduce into the room. On one end solder a suitable plug.
Is the antenna cord can use a whisk of beam segments thick, with a diameter of 1-2 mm copper wire with a length of half a meter. The bundle of wires is inserted into a suitable metal Cup, e.g., aluminum from the condenser and filled with solder. The antenna is fixed on the highest possible place from her room there is a wire reduction.
If you have an external antenna be sure to set the lightning switch. During thunderstorms the antenna disconnects from the radioand closes with a switch on the ground wire.
Advice 4: Where to connect the antenna
A device equipped with receivers and transmitters, equipped with inputs for external antennas. The use of external antennas instead of internal, can significantly improve the quality of communication.
Radios often provided with sockets, indicated by the letter A, or a sign resembling the letter Y, but with an additional third vertical line in the middle. It was at this socket and connect the antenna. If it is outer, it must supply gruzopoluchateljam and ground before the storm.
Some receivers have a socket and for grounding. Such devices cannot be connected to the receivers, mains operated without transformer. On their back wall there is an inscription "the Land is not to include". If the receiver doesn't have a Jack for the antenna, but there is a telescopic antenna, it is possible to connect a crocodile clip indoor antenna - insulated wire with a length of several meters. The reception will be better.
To improve reception on the low bands can be wound a few turns of wire right on the case of small-sized receiver so that the axis of the resulting coil was parallel to the axis of the magnetic antenna. One of the coil pins connect with the same indoor antenna.
TVs was previously the clamps for flat 300-lot antenna cable. Now all the TV's coaxial jacks provide for connection of the 75-lot cable. To connect this cable with the device, use a standard antenna plug. Indoor antenna with 300-Ohm flat cable are available so far. Their kit includes an adapter with a matching transformer. Built-in adapter plug can be included in a coaxial socket.
Modern TV has one socket for a broadband antenna, operating in all ranges. An old TV may have separate jacks for antennas VHF and UHF range, as well as an additional socket with a voltage divider 10, which is suitable to use with a strong signal. The slot antenna may be provided with an inscription In Antenna, Aerial or similar, or a stylized letter T, as if consisting of two letters to Mr. mirror and ordinary.
Stereos are equipped with sockets for the loop antenna low frequency ranges and antenna-dipole high frequency ranges. If you lost the first antenna, wrap ten turns of insulated wire on the frame with a diameter of ten inches and connect to the respective jacks. If no second antenna, take TV indoor antenna with 300-Ohm flat cable, detach the adapter is a transformer and plug into jacks music center designed for dipole. These are the clamps for antennas with a label Antenna, Aerial, AM loop (for loop antenna), FM dipole (dipole), etc.
Many cell phones have a small coaxial socket for an external antenna. If this socket is not directly on the rear wall, it may be under the battery cover, and the holes in the lid may not be. But then to use external antenna only with the cover removed, which is inconvenient - the battery may fall out.
To connect and disconnect the antenna very carefully, so as not to spoil the miniature nest. The plug must be factory made, designed for use with cell phones. Labels next to the aerial socket usually do not. It is cylindrical, has a diameter of a few millimeters and gilded. Sometimes it is not at all, even under the hood.
The radios range CB (27 MHz) external antenna connected 75-, and 50-Ohm coaxial cable. Antenna socket and plug standard BNC are designed to preclude drop thanks to the use of latches. To turn on the radio without an antenna is impossible - can deteriorate the amplifier of the transmitter. The same can happen from using the wrong antenna, and a 75-lot cable instead of 50-a lot and even just in case of breakage in the cable. The portable radio antenna socket is located at the top, have stationary or car - on the rear wall.
Satellite antennas are connected to receivers not directly, but through the converters, fortified directly into "Plates". For this purpose, special sockets, plugs and cables with low attenuation at a considerable frequency. The same cable serves for voltage supply and control the Converter. Socket for connecting the Converter located on the rear of the receiver.
All connections produce when de-energized equipment.
Correctly use the lightning switch external radio antenna.
Correctly use the lightning switch external radio antenna.
Note that some devices connect an external antenna is prohibited. For example, these radios band PMR446. For them, in addition to maximum output power, the regulated and the type of the antenna - integrated, i.e. built in.
