Pardon my electrical ignorance. I have seen kits like the Radio Shack 278-758 for constructing antennas, and I was thinking about trying to use this in my attic to get a nice, long AM antenna. Then I thought, what's to keep me from taking a nice long run of RG-6 quad shield coax, stripping 30 feet of it or so it to it's center conductor, and running it straight back to the receiver? So, my question is, what's to keep me from doing this? And if the answer is nothing, would the same sort of setup work for an FM antenna?
