xpert1974 Posted June 4, 2002 Share Posted June 4, 2002 I want to connect my PC to my tv in the hall. Any idea how long w/o much distortion a s-video cable can go? Where can I get the cheapest s-video cable? Quality does not matter cos the signal is from comp tv out Link to comment Share on other sites More sharing options...
Jag Posted June 4, 2002 Share Posted June 4, 2002 Using standard Belden cable for S-video, 10m runs should be pushing the limit of quality. If quality is of little concern, then 15m can still provide reasonable PQ. If use for longer runs, I suggest break out S-video cable to RG-6 cable for runs exceeding 10m. Such RG-6/RG-11 can run to as far as 25m/40m. Link to comment Share on other sites More sharing options...
Ender1624705735 Posted June 5, 2002 Share Posted June 5, 2002 Jag, Can you explain what all these RG-6/11 rating means? Is it similar to AWG rating use in gauging the thickness og the cables? Link to comment Share on other sites More sharing options...
Jag Posted June 5, 2002 Share Posted June 5, 2002 RG-59 co-ax cables is the industry standard for 75ohm video cables. Its a battle proven way of transfering signals with minimum loss & interference thru co-ax. RG is short for Radio Guide. Invented by the americans for their radar system in WW2. The number represent the specs drawn up for that number type. Today,a cable manufacturer would specify "RG-59 Type". It means the cable capacitance, signal propagation velocity, dimension, loss ..etc... all obey the RG specification of that number. RG-59 AWG is 20AWG. SCV uses this type of cable; under a different manufacturer product number. But its still RG-59 type. Next up for 18 AWG would be RG-6. Thicker thus less attenuation or loss. A great step up in terms of signal integrity. Used commonly in studio setups. Not easy to work with but still manageable. 14 AWG would be RG-11. Very thick and not very easy to work with. 10 AWG would be overkill and would not be practical. I won't cover that. Attenuation @ 100MHz: RG-59-> ~10dB/100m RG-6 -> ~6.5db/100m RG-11 -> ~4.9dB/100m A rule of thumb, longer the run, the thicker the cable. In US, RG-6 is used for in-house cable runs, where outdoor BUD (big ugly dish), a semi-rigid thick co-ax able s used to minimise attenuation.
