    Hello!
    I may have a stupid question, but what is the difference, and whether it is at all, between the satellite TV cable and the terrestrial TV cable. Namely, I am currently using a mesh antenna. I want to buy a digital flat and I do not know if I will be able to use a cable from a mesh antenna to a satellite antenna. The net will not be used. Thanks for the help!

    Generally speaking, these are the materials and technology used to build the cable. To be more precise, the difference lies in the attenuation of the cable. "Terrestrial" cables work practically up to 860MHz, while satellite cables up to 2.5 GHz and have lower attenuation in the high frequency range compared to "terrestrial" cables

    If the cable you have is in good condition and not too long, you can use it

    If it is impossible, it can be a problem, but expect minor problems.

    The cable is not too long ... about 10m. Thanks for the advice! I will try ... most I will have to replace.

    Hello

    Yes, from my own practice - I have not yet found a cable for "terrestrial TV", i.e. up to 890MHz (of course, a man does not need to know about everything ;) - I omit the 25-year-old, single-shielded cables used in old collective networks - although I saw "hung satellites" on such cables as well.

    As my colleagues mentioned, the quality and, most of all, the attenuation of such a cable is important, with short distances you may not notice the difference, with larger distances it is important.

    Put on a satchel and see for yourself, to be sure, at least 80.

    The so-called regular, TV (- RG6U) and Sat (e.g. WDXpek). The difference in parameters and price - 0.7 PLN / 1m and e.g. 2 PLN / 1m for Sat, material, etc.

    I obtained the information that interests me. Thanks all! I'm closing!

Topic summary

The discussion centers on the differences between satellite TV cables and terrestrial TV cables. Key distinctions include the frequency range and attenuation characteristics: terrestrial cables typically operate up to 860MHz, while satellite cables can handle frequencies up to 2.5GHz with lower attenuation at high frequencies. Users noted that if the existing terrestrial cable is in good condition and not excessively long (around 10m), it may still be usable for satellite connections, although performance could vary. The importance of cable quality and attenuation is emphasized, particularly over longer distances. The conversation also touches on the cost differences between regular TV cables (RG6U) and satellite cables, with satellite cables generally being more expensive due to superior materials and specifications.
