Abstract

An in-house coaxial network includes an input (10) capable of connection to a cable or satellite television signal provider and which is connected to a signal splitting device (12) for communicating the signal to a plurality of outlets in the form of subscriber equipment, wherein a filter (36: 38) is positioned between the input (10) and the signal splitting device (12). The filter is adapted to reflect signals outside a frequency pass band used for data transfer thereby to reduce signal loss. By reflecting signals outside the frequency pass band, whilst at the same time passing all signals in the frequency pass band, the filter (36: 38) significantly reduces the signal loss between the plurality of outlets (16).

Claims

1. A coaxial network comprising an input capable of connection to a cable or satellite television signal provider and which is connected to a signal splitting device for communicating a signal to a plurality of outlets in the form of subscriber equipment, wherein a filter is positioned between the input and the signal splitting device, the filter adapted to reflect signals in a frequency band used for data transfer thereby to reduce signal loss.

2. A coaxial network according to claim 1, wherein the filter is adapted to reflect signals inside a frequency range between 3 and 65 MHz or 900 to 1500 MHz.

3. A coaxial network according to claim 1, wherein the filter terminates the input, whilst still reflecting all signals outside the frequency pass band.

4. A coaxial network according to claim 2, wherein the filter terminates the input, whilst still reflecting all signals outside the frequency pass band

5. Use of a filter positioned on an electrical communication path between a cable or satellite television and signal provider and a splitter so as to reflect signals in a frequency band used for data transfer which are outside a frequency pass band of the electrical communication path, thereby to reduce signal loss between outlets.
