If the received signal is good enough (both in terms of level and C/N), it could possibly be used. The use of conventional splitters involves an impedance mismatch, which in turn results in signal loss, since splitter's impedance is 75 Ohm while the impedance of the professional systems (both panels and active systems) is 50 Ohm. It is advisable to use 50 Ohm receiver systems (professional antennas) as well as 50 Ohm cables and splitters.
Yo do NOT need to make any modifications. Your home TV coaxial network is the only thing you need. You will be sharing the Internet access as soon as you plug in the coaxdata to the TV outlet.
Many devices among the TV and IF signal distribution equipment have an inductive nature. Transformers are used, which are shown as a short-circuit in a multimeter. Therefore, the presence of a short-circuit in direct current in a distribution equipment does not mean that the equipment is damaged.
Even though the equipment in a SMATV (5 MHz - 2150 MHz) could be used in a CATV installation, the sums do not add up the other way round. The same goes for coaxial cable: the copper-clad steel cable typically used by cable operators is not recommended for DTT and SMATV distribution networks. The difference between a cable with a steel core and a cable with a copper core translates into a quite important difference in terms of conductivity, resistance, and most importantly resistance to corrosion. At high frequencies the external layer of the copper-clad steel plays the role of a copper conductor, but that conductivity is progressively lost as environmental conditions attack the steel. Junctions between devices are particularly affected by these circumstances, and it is there where impedance matching is most critical,since the quality of the signal depends on it to a great extent. Conclusion: even though the laws allow the use of copper plated steel in operator networks, copper cable is more suitable for SMATV networks; ultimately, it is suitable for all networks that need to keep their characteristics inalterable.
Humidity and liquid getting inside an equipment is the main cause of failure in electronic equipment.To prevent liquid from entering the equipment and protect the amplifiers, all the protection measures must be applied during the installation of the respective coaxial cables. Hence, for outdoors coaxial cable installations, the cable should always have a PE finish, instead of PVC. PVC finish should only be used indoors. Furthermore, you should always make a loop with the coaxial cable that will be connected to an amplifier or antenna, in order to prevent the liquid from directly entering the amplifier through the connector. Connection between cables should always be avoided outdoors, since they are weak points and water could enter them, or enter the system through them.
Every conductor has a limit to its bending; once exceeded, the cable will not maintain its electrical properties. For the coaxial cable, besides impedance variation, excessive bending beyond the minimum bending radius could cause the shielding foil to break, which could impact the capacity of the cable to protect the signal from interference. In cases where the cable has to follow paths with radius below the minimum bending radius, the solution is to use shielded angled connectors. There is not any specific rule to establish the minimum bending radius. Manufacturers and operators establish their own criteria. In practice, it is usually not recommended to go to radius below five times the cable diameter.
