technical terms that means massive interference. I have isolated it to the
wall socket because if I take the socket away and terminate the cables with
a connector they work ok. What I want is an socket that has two outputs
that are screened from each other. The only other solution is to put a
second socket in and have a single outlet in each one. But they need to be
a fair distance apart and that doesn't suit me.

Hi Phil,

Even if you could get screened sockets...which I have never seen, the
signals are
probably so strong that you would get bleedthrough from the cables running
adjacent to
each other.

Can you not adjust the RF output of one cable box to a different frequency
or better still
connect to the video via a SCART lead so avoiding the RF connection
altogether.

This was a problem for many people when ASTRA 1D went live.
People with early non 1D compatible systems who lived in parts of the
country
where terrestrial TV is at the top end of the band CH52-68 found that they
could
see Satellite pictures interfereing with normal TV. This was due to a
combination of
high level signals at the same frequency and poor quality coax running
parallel for long
distances.
