[QUOTE="Terryl, post: 966526, member: 369937"] Sorry, I didn't see the part about others on the system, old eye balls getting to me. Best bet is a bad connection somewhere, or someone put a coax staple through the coax jacket a long time ago and the problems are just showing up now. (water got into the coax) Or a bend in the coax that is too sharp of one, RG-6 (or it's equivalent) should not be bent at a sharp right angle, but at a radius no smaller then lest say your wrist, a very sharp bend (or a kinked coax during pulling it) can over time cause the center conductor to move too close to the shielding, this causes the 75 ohm inductance to change due to the coax capacitance changing, or if too sharp the coax resistance (not the 75 ohm but it's DC resistance) could even change over time, water can also cause a big problem if it got inside the coax somewhere and has rusted out the center conductor if it's copper clad steel.
