How to connect cable TV to your TV

Television can brighten up leisure time, and modern people cannot imagine themselves without such a pastime as a sofa in front of the TV. But to watch it, you must first connect the cable. How to do this correctly will be discussed later in the text.

What you need to connect

Regardless of the type of connector, you cannot do without a cable. For our purposes, we will need a coaxial cable with a resistance of 75 Ohms, preferably the following brands:

• RG 6U;
• SAT 50;
• SAT 703B;
• DG 113.

These types of cable are suitable for outdoor and indoor installation. The specified marking is applied on the side surface of the braid, along with an indication of the manufacturer, product quality, wave resistance and meterage mark. The TV, splitters and amplifiers are designed for a resistance of 75 Ohms, so this parameter is fundamentally important.

You will also need a plug to connect to the TV. Its installation does not require any special skills or permission to work with high voltages - electric shock from the antenna cable is excluded, since it uses high-frequency currents of very low voltage.

Connection instructions

Most modern television equipment provides for the connection of a so-called F-plug. There are three main sizes of plugs, depending on the cable cross-section.Before purchasing, you should make sure that the components you are purchasing are compatible.

There are two ways of wrapping - with and without a fold of the shielding braid. The first method is more reliable, but the second is used if the plug cannot be screwed over the braid.

The first step is to carefully remove the top PVC braid using a sharp knife so as not to damage the cable shield. The incision is made a few centimeters. Then the braid is folded to the side and cut off. Carefully release a small section of the inner copper wire.

It should be noted that the foil with which the cable is wrapped and is a conductor is often covered on the inside with a layer of polyethylene for strength. This point cannot be missed during installation - polyethylene insulates the current, therefore contact must be between the connector and the side of the foil where the PET layer is missing.

Attention! If the cable cross-section is too thin for a given plug, apply electrical tape under the foil several turns.

After installation of the part of the plug intended for winding onto the cable is completed, the internal copper wire is shortened so as to leave no more than 3-4 mm of core. After this, screw the second part of the F-plug tightly, and the connection is ready for use via the receiver.

Connecting cable with old antenna plug

Before the advent of F-plugs, products of a slightly different design were used, which also did not require soldering. When installing Soviet connectors, it was impossible to do without a soldering iron. Since they have already become a rarity and cable is not connected this way, there is no point in considering them within the scope of the article.

What you will need

For installation you will need the same cable as described above.In addition, you will need an old-style plastic plug. You will also need a sharp knife and pliers or wire cutters.

Instructions

The process begins with disassembling the plug. To do this, by rotating counterclockwise, the plastic case and its metal part are separated. The housing fits onto the cable. Then about a centimeter of PVC braiding is removed in the manner described above, and about 5 mm of shielding foil is trimmed.

When inserting the cable into the plug, pay attention to the absence of contact between the screen and the central core. Using pliers, crimp the foil with the petals of the connector. You should not squeeze too hard to avoid damaging the structure; it is enough to achieve good contact between the surfaces. After crimping, tighten the screw intended for fastening the central copper core until it stops.

The final stage is to screw the plastic case onto the metal part, after which you can connect the connector to the TV.
