Where is the signal coming from?

During the storms yesterday the inlaw's aerial mast broke and was left
hanging on the cables banging on the stair window so FIL was worried about
the window getting damaged so went up on the garage roof, cut the cables and
put the broken mast and two aerials away in the hut.

Later they reported that they were still receiving some channels, the main
BBC ITV channels plus some more. I couldn't figure out where the signal was
coming from so I went up for a look.

Some years ago when they got a new digital TV I told them to get a decent
aerial installed and to ask the installer to run a new CT100 cable since the
existing one had a joint and the cable running up the cavity was the old
brown leaky stuff. I did the original joint in the loft with two F-type
connectors and a coupler. The installer erected an Antiference DX8WF,
didn't bother with the new cable but made another joint in the loft with the
two cables side by side, screens twisted together and the centre cores
stripped back about an inch and just twisted together then taped up. So how
are they getting a signal?

The complete installation is as follows.
Small loft aerial in the loft feeding to an upstairs bedroom. Still working
Small aerial on the now broken mast with external cables feeding the
kitchen. Broken since the cable is cut.
DX8WF on the broken mast but the main TV is still getting some channels but
since I was in the loft disturbing the cables, they have lost some more
channels.

I can only think that the signal is coming in via the leaky cable running up
the wall cavity or the joint in the loft.

Anybody care to comment

They at 19 miles from Craigkelly.

Undoubtedly the un-screened taped join in the cable. The join as you
described it sounds like it's not far off a half-wave dipole, and it's
probably got a LOS view of the transmitter apart from the roof tiles.

Frankly I'd be more surprised if it didn't pick something up.

Where do these bodgers come from. I remember I had some put up an aerial
some years ago, all the cabling was well done but oh the brackets.. Too
close together and of course, the screws eventually came adrift.

They drag them off the street, give them half a day training and
suddenly they're 'ae-reeull expurts'.

The first Sky Digital box I had, I had no choice but to agree to the
cowboy Sky installer erecting a dish - the knobhead used an old piece
of sat cable I had left spare with the intention of re-connecting up
an existing dish from analogue days. That meant I had to re-do the
****'s 'work'.
As little work as possible for the money and get in, get out as quick
as possible.
