Yes, assuming your cable to preamp is 15 inches in length, or longer.
If you use four ferrites. Place two near the junction close together. Place the other two centered around 15 inches down the cable.
If you use three, then place two at the junction and one at 15 inches.
With calculations or computer simulations one could obtain an estimate of the available improvement, or indirectly measure it on a test bench.
After two or three ferrite cores on a cable, likely the signal strength improvement available with more ferrite is in the low tenths of a dB range.

Tripleo thank you. It's all very clear to me now. I will take it step-by-step pictures, and I will report back. I also want to thank my other friends sheer on TV Fool and the other forums. Sev, Rabbit, Tim and Calaveras.
Seems like I always pick something complicated to do and it's hard to get input that way. So, I really appreciate it.
