Wiring in single-family homes

It often happens that cables put in a rush without any consultation with specialists in particular kinds of installations cause limitations on certain functions, speed limits etc. Using the cables described bellow one can be sure that the cabling will be up to date and not being affected by troubles in the future.
Which coax to use in antenna installation? Without any risk one may choose the Triset-113 (E1015_100). It is certified coaxial cable suitable for distribution of terrestrial and satellite TV signals.
The cable features excellent screening efficiency within the whole group of distribution cables. It is important for attenuation of external interferences. Another major characteristic of the coax is low loss.

Telephone and computer network in single-family home. It is worth to consider twisted-pair CAT5 wiring when planning indoor telephone network inside a single-family home. Such wiring will allow in the future for additional extension of the installation by data networking facilities (two pairs will be used by Ethernet network and single pair will be used by telephone link) without laying additional cable.
However, for all that who are building house and planning wider use of computers, we recommend to place two CAT5 cables. When one wants to run at least 100 Mbps local network, there will be needed all pairs of UTP/FTP cable. Instead of putting additional telephone cable it is better to double the transmission cable. Such solution is more flexible and has potential for higher rates of transmission in the future.
The proper CAT5 cable for fixing it permanently will be the version with solid conductors, for example UTP (E1508_305). More about twisted pair cables here.
Structure of typical CAT5 cables
Video door entry systems. Coaxial cable is needed for transmission of video signal, two additional pairs - for power supplying and audio transmission. Usually all the wires will be put into the ground or, in general, work outdoors, so they have to be protected against moisture penetration (through micro cracks on the surface).
On account of that it is not gelled cable, it has to be placed inside conduit pipe made of plastic, and carefully sealed at the joints. It also should be paid attention to voltage drop over power lines, to be sure that the equipment will work stably. Typical value shouldn't exceed 1V. A good solution is to arrange the cabling in the following way: to use coaxial cable for video transmission, single pair for audio transmission, and the shielding conductor aside from being zero signal rail should be connected to zero (or "-") voltage rail of power supply, whereas two remaining wires linked in parallel to "+" connector of the power supply. Typical range of this combination is up to 100 m.

Audio - video cables. According to information given by some companies that offer high class audio equipment, total resistance of connection between power amplifier and the speaker shouldn't be higher than approximately 1/100 of nominal speaker impedance, so in the case of 4 ohm it means not more than 40 milliohms.
This relation allows to use wires with smaller diameter in the case when it is anticipated to employ speakers with higher impedance. Additionally, it should be paid attention to similar length of the wires laid to both speakers, to ensure the same parameters of both channels (or of each pair of them in the case of multiple channels). An excess of the cable in the shorter route shouldn't be rolled up into a coil due to significant increase of inductance, which causes upset in balance between channels.
Speaker cables - the thickest ones are the best but also the most expensive - one should find a compromise
The most frequently used speaker cables are those of TLgYp type. This type of cable consists of two wires, in the form of soft copper stranded conductors. Wires are placed in transparent isolation coat made of polyvinyl (PVC). Wide range of diameters is available, from very thin 2x0.35mm to 2x6.0mm.
