Hi guys.Recently, while adding some insulation to the crawl space of my house, I noticed that the coaxial cable that provides my cable tv signal is crossing an 15 amp a/c power line. When I say crossing, I mean that it is actually touching the a/c line and runs at roughly a 75 degree perpendicular angle to it. Will this degrade my tv reception, or is the frequency of the video signal so high that the a/c and all of the RFI/EMF that it gives off will not bother it?
If I have to separate the two cables, it will require me to splice the coax, because it is installed very taught along the studs of my house, and there is no slack to space it from the a/c cable. Will splicing the coax, and attaching it to another length of cable via f type connectors pose a downgrade in reception as well? I am assuming that where the two lengths connect could be a source of RFI/EMI seepage into the signal, but I'm not sure. Any of you brainy-type guys have any answers?
Thanks,
Rob
Follow Ups:
Crossing is bad, try to get them to cross as close to perpendicular are possible to minimize the effect. Touching is bad too- try to separate them, even if it is a little bit by wedging something in between. Try to use something inert like a piece of ceramic.
Splicing the cable would probably do more harm than good in terms of adding extra connections, foreign materials (even if they are gold palted jacks), etc.
If you are worried you could tryto use a line conditioner (Monster has some cheap ones that clean cable feeds) and see if it helps at all.
If it help, it is a cheap easy solution. If it does not help then your cables crossing is not too big a deal.I think there are probably bigger things to worry about (that have more of an effect)
