Communal tv

Lancroft offers design, installation, and maintenance of fibre and traditional IRS systems.

An IRS collects broadcast signals from terrestrial and satellite transmitters via its communal aerial/satellite rig, as well as FM and DAB radio. The signals are then distributed by a series of multi-switches in the risers to a master point in the apartment or house, enabling residents to view their required TV channels.

The advent of Fibre IRS has simplified the design and installation process, as fibre technology experiences no loss of signal even with long cable runs.

For example, we were asked to inspect a large existing system at an MDU development in London where signal losses were a significant problem. After investigation, we found the cable runs from the LNB to the head end were quite long, resulting in substantial signal loss. We therefore replaced the LNB with a fibre LNB and installed new fibre backbones to the head end. This ensured no signal loss at the head end, and the signal into each apartment is now excellent.
