Audiovisual links

I have found these UK suppliers of cable and connectors to be quick and reasonably priced and to have a good range in stock: and

Tools, electrical boxes, blanking plates, conduits and safety equipment can be got at good prices in the UK from: As a bonus the staff are more cheerful than Screwfix.

For electrical cables, trunking and hardware:

For aerials, masts, amplifiers and cables:

For satellite dishes, LNBs, switches and receivers:

I gathered much of the information that was new to me from links in the immensely useful website:

I also had a lot of good information and advice about satellite installations from the uk.d-i-y newsgroup, especially from Ron Lowe, Andy Wade and Andy Hall. For a superb site containing advice and help and an extraordinary gallery of pictures of some of the horrors put up by amateurs and dodgy professionals see Wrights Aerials at:

Cycle crash data and quotes

Look under "Bicycle safety" in Wikipedia

Royal Society for the Prevention of Accidents fact sheet - click to download

"One cyclist is killed every two and a half days on Britain’s roads (146 people every year). Six cyclists are seriously injured every day. These are cyclists sustaining injuries ranging from broken bones to brain injury or paralysis. 37 cyclists are slightly injured each day. This means 16,196 people suffer injuries on Britain’s roads every year. Of those who are killed or seriously injured a quarter are under the age of 20 and the number of cyclist deaths has increased over the last few years from 114 in 2003 to 146 in 2006. A quarter of those seriously injured or killed are children." "A way of assessing the risk involved with cycling in the UK is to consider (based on the risk per hour of travelling) the length of time one would have to travel to have a one in a million chance of being killed. By air – 4,300 hours By car – 10 hours By pedal cycle – 2 hours and 40 minutes! "
