Ruby:
It is not unusual for a few strands of the shielding braid to appear outside the connector body. The cable has an inner core surrounded by an insulating sheath. That is wrapped in a braiding of silver wire and often has a sheath of silver metal ribbon inside that. The inner conductor shows as the central pin at the end of the connector and the braid is in contact with the outer body of that connector. In fitting the cable into the connector the technician strips back the outer plastic covering a short way, folds back the braiding (and the ribbon is present) and then carefully removes part of the inner insulation so the core is exposed. That is then fed into the 'F' connector so the inner core and outer metal braiding do not touch each other. If the amount of outer insulation removed is longer than the depth of the connector then some of the braid will appear outside. That is not a problem at all.
The silver appearance is because the copper wires have been plated, which is not a bad thing at all. 90 is not expensive to have a dish, LNB and cabling installed for reception of Freesat. If the work was done by a professional installer it should be reliable and be covered by a work guarantee.

Paulj: If it keeps happening around 9pm, thats often because something nearby is 'leaking' and giving out interference. A dodgy timer, etc is a classic. Search for 'single source interference' on this site.
Certainly check all the signal levels - if you've got breakup, its usually down to interference, or too much/too little signal strength, and then narrow it down. Certainly my HD channels are less tolerant of either low or high levels.

MikeB,
TV's from myself and a neighbour both say HD mux sandy heath ch21 has a low signal quality/strength 10%/50% versus other muxes ch24 with 50%/50%.
channel 5 hd now seems to share this mux (added fairly recently but I cannot see when) so I wonder if there is some correlation with problems (mux sharing more channels) ? do you know when 5hd was added
Cheers, Paulj

Dot: Postcode HU17 8UQ, no signal since last night on BBC Freeview channels on either of two separate Freeview boxes (lounge & bedroom). Intermittent on ITV channels, like weak signal. Fine until last night. Roof aerial.
