| 695244 | 2008-08-06 05:37:00 | The spark will have come as you burned out the power supply which feeds the receiver at the focus of the dish. :D The RF signal might not need the shield of the cable, though it's better with it. The power feed has to have the shield to be the return conductor. It will only be 12 volts of so, so it's safe enough. It might have been cheaper to buy a made up cable before you got out the blue and white striped apron. ;) Crimp F connectors are quite simple to fit, with the right tools. Without the right tools, I wouldn't try. :D |

| 695246 | 2008-08-06 06:22:00 | the voltage in the cable will either be 14v or 18v depending on setup. i can't remember the current they normally draw and it depends on lnb. i think decoder is around 1 amp max. its quite safe, i doubt you will blow the decoder either. tv is actually worse, i thinks 110v at the aerial socket. current is limited to safe levels by isolating caps. however things get interesting when they go faulty ;) for connectors, you can get twist on F connectors which saves you guys at home buying crimping tools. there is a nack of doing them tho. for some dumb weird reason sparkies love the twist on connectors (they stopped being used in the aerial industry 10-15 years so buggered if i know why they sparkys like to use them) and from what i've seen very few know how to fit them. to fit twist on F connectors...... DO NOT USE THE FANCY WIRE STRIPPERS. cut out side sheath to a decent length, FOLD BACK the braid, cut the internal insulation and foil so there is about 4-5 mm left. make sure fol isn't swished down or touching centre wire. take half the braid, twist it together then roll it around the internal insulation/foil one full turn in the direction of you twist the F connector on. if its too long trim it back. keep rest of braid folded back. then twist F connector on, the twisted bit of braid will bunch up inside the F connector giving a reasonable connection while the rest of the braid has the thread of the connector bite into it. the more braid folded back the harder it is to screw on but the better the connection. i've seen a lot where they use the fancy cable strippers but it leaves the braid really short. then they often don't fold the braid back which means there is no pressure on the braid. the braid just floats inside the connector making poor contact and will give you lots of problems. |

| 695248 | 2008-08-06 21:42:00 | Thanks for the replies guys. I went on a complete mission and actually found 2x "dead" Sky wires coming from the roof (which must have been for an old satellite dish) and could remove the twist F connector from one of them. The reason for the faulty connection was there was actually no proper F connector there but I fixed it like the manly man I am. Now excuse my whilst I exfoliate and moisturize. | silu (9854) | ||
