I was tryihng to show the isolation of good quality UTP is around 63dB.
63dB is very good for a 1V video(RF from 0~5MHz), not so very good
for antena supplied RF.

Not near quite enough for my location.

Feel free to use any cable you wish.

I was trying to help newbies avoid the mistakes that I had already
made.
