Coax cable interference; do I need quad shielding?

OK, here's the setup. First, I'm receiving only ATSC over-the-air signals. I don't pay for a subscription to get TV. (From this you may also infer that I'm a cheapskate. ;)) I have an amplified outdoor antenna, connected from the indoor amplifier to a splitter, and then to two ATSC receivers.

Now the signal strength on some channels is poor at the best of times, but I've found that if the indoor cables are in the "wrong" position some channels disappear, while if I get them in just the right position everything works. This is not ideal, and I'd like to fix it. (This isn't normal with ATSC, is it?)

I infer that this delicate positioning means I'm getting some interference from power cables and/or power supplies to various devices. Is this a safe assumption?

OK, so I went to Wal-Mart the other day, and they seemed to have two grades of coaxial cables: double-shielded and quad-shielded. The quad-shielded cable costs more than twice as much as the double-shielded. Is it worth it? Also, they have two grades of splitter: a regular one and one covered in gold with lines drawn on it from input to outputs. I think the gold-covered one was only about 30% more. Is it worth it?

And will any of this work better than the 10-20 year old cables I have now?

Should I look at Radio Shack instead?

Thanks!

If your cables are rg59 grade you should upgrade to rg6.
quad shield is not necessary for ota.
running multiple amps is not recommended.
Much can be learned about this at avs forum and digital home forum.
