[QUOTE="rolfw, post: 1077414, member: 175057"] Most of the UK installation trade use dbµv (microvolt), so will be positive figures, 10m of good quality RG6 satellite cable loses anything between 20 and 30dbµv per 100 metres for the 1,000 to 2,150mhz range. For a standard universal LNB, it is recommended that there is a minimum of 60dbµv ish at the receiver (I prefer a little more), Sky seem to think that for Q it should be a little higher, hence why they tend not to use WF65 cable (smaller core) as much for Q installations which has a higher through loss 0f 30-50dbµv per 100m.
