Difference between distributor and turnout (usage and notes)
The name looks like the distributor and the turnout well. Moreover, because the usage looks like, too it is likely to be used it without understanding the usage well, and by mistake. It thought about the distributor and the turnout.
What is the distributor?(The distributor evenly divides the signal.)
The distributor evenly divides an electric signal. If they are four distributors, the signal is evenly divided into four. The signal of the size as which any output signal is the same is output.
What divided into 1/4 per four output terminal is output in case of four distribution. Because the signal level from the output terminal has the distribution loss, it becomes 1/4 or less of the input signals.
Usage and notes of distributor
Because the distributor is an equipment that evenly divides the radio-frequency signal (signal of the electric wave), it is generally used for the usage in which the signal from the antenna is evenly divided into each room back of the ceiling at home.
The loss in the distributor increases by the frequency high. Moreover, the more it increases the distributed number, the more the signal weakens. Therefore, it can enjoy making it to the minimum requirement in the number of distribution and it enjoy a more beautiful image and the sound.
There is the indoor type of of the type distributed the waterproof type and indoors of the type distributed in on the roof and outdoor distributor. Please note that moisture and water enter, and longevity contracts if the indoor type is used in outdoor though you may indoors use the waterproof type.
What is the turnout?(The turnout diverges and takes out a part of the signal.)
The turnout takes out only the amount of the signal to need it of the trunk line while the distributor evenly divides the signal. The level output from the divergence terminal lowers more than the level output from the output terminal.
Usage and notes of turnout
Because the signal becomes small, the divergence terminal uses the divergence machine for the usage in which the signal is taken out on the way of the cable than the output terminal. Generally, there seem to be a lot of one to take out the signal that decreases more than the input signal by ten dB(It is an electric power and 1/10) or 20dB(It is an electric power and 1/100).
The turnout is a little attenuation, and used for the usage in which the electric wave is subdivided in the direction of the divergence in the main usage while the distributor evenly divides the electric wave. There is a usage that diverges to each home by the cable television, too.
It is used to wire for the television in a general home and the apartment house, etc. well. It is used at the wiring technique that sequentially subdivides the electric wave to each room after the electric wave is made strong with the booster of one degree. In the turnout in this case, the wall terminal for the divergence is sequentially connected.
We will recommend the wiring technique not to use the turnout in a general home but to distribute the signal to each room with the distributor evenly.
There is the indoor type of of the type distributed the waterproof type and indoors of the type distributed in on the roof and outdoor turnout, too. Please note that moisture and water enter, and longevity contracts if the indoor type is used in outdoor though you may indoors use the waterproof type.
The wave obstruction has been noted directly for the turnout.
As for the turnout, the electric wave in the antenna terminal of the television tends to weaken because there are ten dB or more divergence loss, and the losses are generally larger than distribution. Then, the electric wave enters the antenna terminal directly, and the probability of obstructing the signal of the cable that the wave obstruction happens directly rises. In this case, it is necessary to construct it appropriately with an antenna terminal and an antenna plug with good shielding performance.
Notes when wall terminal is turnout
There is a person to whom reflecting of the television of the room changes the antenna terminal and , wall without permission in the apartment and the apartment house, etc.In this case, if the wall terminal is not appropriately chosen, reflecting of the television of the room after that might become bad.
It is time when it is often has changed the turnout (divergence terminal) to the distributor. Moreover, when it is awful, might it change to a usual antenna terminal, and the wiring after that be removed. Naturally, the television is not watched in the room after that.
