Check the antenna cable to the serviceability

Reasons check the antenna cable

1. If the cable is old and needs to be replaced.
2. When do remodeling or home repairs.
3. When you move into a new house and ignorance, works whether the antenna cable to the TV.

cable with proper treatment can last for a long enough time.For proper handling relates air temperature, humidity, the presence of drafts, the mechanical impact.As for the part of the cable, which is on the street, her care on your part will be difficult, because its absence reduces the strength of the product and its longevity.

Quick guide: how to check the antenna cable.Step 1: Turn off equipment and cables

To check the cable need to disconnect the TV from the mains, pull out all the cables.

Difficulties emerge when it comes to the common antenna for TV, which does not have a separator for apartments and it is difficult to approach the end.Check serviceability of the cable can only be from the tip, located in the apartment.

Step 2: Check the resistance between

ring and pin contacts, check the resistance, which can be less than 20 ohms due to the amplifier located in the stairwell and a resistor.And if the voltage is equal to 0 or very close to it, then the probability of closure is increased by several times.Tension with the readings in the form of infinity means that there is a gap in the cable.

much better if both ends of the cable access, but this is not always possible.A simple way to avoid problems is to install home antenna with an amplifier to verify that enough to pull the plug from the socket and plug.Next, remove the cover of the antenna, and an ohmmeter, check the cable components in this order: Braid - center conductor.Indications of resistance, if all goes well, there should be zero.And if you try between these components, you are infinite.

Step 3: Connect an ohmmeter to both sides of the wire

If the cable is long, the ohm meter can be attached at both ends.First unplug all appliances and equipment, then connect the ohmmeter from the connector to the central core and sheath.Indications on the ohmmeter - infinity.Next to the second end of the wire and connect a jumper on the ohmmeter resistance should be a figure approaching zero.

Step 4: Check the outer integrity

carefully check the cable for external strain.It is very likely that you will be able to find a dent on the cable, which will need to clean up, and the contacts splice.If the strain is not detected, connect the ohm meter to one side.If the break is still known, at the other end of the cable is needed a jumper.However, by closing switch is not required.

In addition to this, it is possible to test the cable mechanically, ie. E. Ponazhimat it.If you notice a change in the numbers on the ohmmeter should fix the problem on the cable.It is important that such damage may be more than one, or even two, so the search must be thorough and accurate.And when all the problems will be resolved, disconnect the ohmmeter and the jumpers and connect the cable to your TV, check the result.
