Hamilton Hartland Digital Screened Non Isolated Satin Steel

Isolated outlets will filter out any interference.

If a 2 way signal is required, e.g., for use with satelite hard wire extensions, then a non isolated outlet is required.

The non isolated version is the standard version for coaxial and satellite installations.

An isolated outlet provides a 1 way signal. It blocks the return signal. It is mainly used when a satellite dish or aerial is being shared, like in an apartment block for example.
