How high should the signal level be?

How high should the signal level be?

Values ​​in the range of 65 percent and more are necessary for perfect HD reception; with normal television picture reception, 55 percent are usually sufficient. In general, it applies to both signal strength and signal quality that higher measured values ​​are better.

What antenna cable for satellite?

If you want to enjoy Full HDTV, the shielding should be over 120 dB. The following details of a SAT cable for HDTV reception should serve as an example: 130 dB coaxial antenna cable. 4-fold shielding.

How long can a satellite cable be?

From 50 m you come to the area where the level is still sufficient (> Assuming 77 db (V) from the LNB, 62 db (V) are still available for the high frequencies; the standard level is from 47 db (V).) , but the so-called inclined position of the signal (> high frequency components fall compared to the low ones. With a 50 m cable this is about 5 db.)

How long can the cable between the LNB and the receiver be?

And here should apply from the dish (LNB) to the multi-switch 50 meters. The multi-switch already amplifies and therefore 50 meters from there. But the 50 meters can usually be exceeded. There are also receivers where you can increase the voltage.

How can you extend a satellite cable?

TV via satellite If the satellite cable is too short, it can be easily extended. All you need is a so-called F-connector and a second satellite cable.

How can you extend coaxial cables?

There are three ways to extend a coaxial cable: Connect the extension cable between the television and the antenna cable. buy a new cable of the required length. Attach an F connector (F double socket) between two coaxial cables.

Can a satellite cable break?

Outside satellite coaxial cables usually weather within 10-20 years, depending on the quality, and then have to be replaced. The outer coating only needs to be damaged somewhere and then water runs in and nothing works anymore. When F-connectors rust, that speaks volumes.

How can I check whether my satellite cable is working?

You can also connect a small battery, shielding minus and inner conductor plus. Then check with a lamp. Or test the shielding of one cable against the inner conductor and at the top with a continuity tester. Last option: Always connect a cable directly to the receiver and look with a voltmeter.

Is there electricity on a satellite cable?

If not every satellite line is clamped to a potential equalization rail, electric shocks can occur when connecting or disconnecting. Not dangerous, but uncomfortable. The receivers supply the LNB with voltage, you can only disconnect all connected receivers while you are tinkering with the cable.

How to mount F connector?

Installation instructions for F-connector / F-screw-on connector. Remove the sheath. First, the sheathing of the coaxial cable is correctly applied to a length of approx. Lay the braid backwards. Expose the inner conductor. Unscrew the F connector. Final check.

Which F connector for which cable?

If the F connector is used outdoors e.g. B … Selection of the appropriate connector. 3 rings4.0 – 4.2 mm2 rings5.0 – 5.2 mm1 ring5.8 – 6.1 mm no ring6.7 – 8.2 mm

Which F plugs are there?

The F connectors are externally coded for the cable diameter by rings in the corrugation. 3 rings: 4.0 mm. 2 rings: 5.0 mm – 5.2 mm. 1 ring: 5.8 mm – 6.1 mm. No ring: 7.0mm – 8.2mm.

How do you connect an antenna socket correctly?

Connecting the antenna socket – you have to pay attention to this The antenna cable is usually already laid and comes from an empty wall socket. Slide the braided shield back over the cable. Next you take the antenna socket – without the plastic cover – and unscrew the screw a little to secure the cable and the strain relief.

Which antenna socket for cable TV?

A 2-hole antenna socket is suitable for connecting TV and radio. With a 3-hole socket, the SAT receiver is connected via the F socket or a 4-hole antenna socket with two F sockets is the right choice for connecting a twin receiver.

How do you connect the TV?

So that you can also receive TV channels, connect either the satellite cable or that of the cable television to the corresponding connections on the television. If your TV set does not have an integrated receiver, you must use an external receiver and then connect it using an HDMI cable.

What does an antenna socket do?

The antenna socket or connection socket provides the signal transmitted via a coaxial cable for connecting the end devices, for example the television sets. With cable television you usually have a so-called IEC connection for TV as a plug and a socket for connecting to VHF radio.

Can you turn an electrical outlet into a television connection?

c) There is NO antenna cable in a socket and NO power cable in a television connection. As a rule, an antenna socket is simply placed separately next to / under the 230 volt socket.

Which socket for TV?

Plug the female end of the antenna cable into the male socket of the antenna socket – it is usually the left socket. If you’re using a separate receiver, connect it to the TV. Depending on the connection options, you can use an HDMI, Scart or coaxial cable.
