by the way.. quickie for the expert. I have a HDTV with Cable-tv. I see a -12 dbmv for QAM and -8.5 for normal. Are these values good or bad. The minus 12 is hilighted as RED. quick config.. 1 line in house (rg6) long(100 feet) to a splitter(in basement).
from there to HDTV set using a small 1 foot lead upstairs and another from outlet (1 foot), and then from there another splitter to a SETTOP box(1 foot) and then HDMI to TV, other line (5 feet) to a VCR.
previous splitter.. runs about 40 feet to 2nd floor where a TV (old style(last century)) is located(and from outlet to TV(5-10 feet).I think most is cheap RG6. Spliters and cable came from friendly CABLE-MAN, when he rewired the outside line from street to house underground feed. picture is ok.. I use phone company for ADSL2 (10 meg they say) service. p.s. I do have a 20-30 foot of cable in excess in a spool in basement. Should I cut it out and put a "connector" in its place? (this long wire was used as a temp till they did the underground work..
winter is bad time for digging. the wire ran from their BOX up a tree to house, and then into a cable-box and then into the house. SO I had extra length. was it wrong to use it(THE EXTRA LENGTH!)?
