I know the basics, but I wanted to know some things: In a house, when running cat5e cable, is it necessary to use plenum cable? Also, I never did learn the difference between "stranded" cable vs "solid" cable. Could someone explain, please? Let's see... What else? Oh, for cable TV, internet, satellite, etc connections, which "rg" type cables are used? What I mean is, what is the difference between rg58, rg6, etc? And, what are these cables used for specifically? Thanks! Chris

I own a two story house in Southern CA built in 1963, and I'd like to run CAT5 to all the rooms in the house. Ideally, I'd like to run the cables through the crawlspace and down the walls to a nice wallpate. But, it turns out that I have an obstruction about 3 feet off the floor in the middle of my external wall preventing me from getting the cable from the attic to the floor. Beside tearing up that section of wall to put a hole in that obstruction, are there any other options for me? I know I could run the cable down through the closet, but that option is less appealing since it seems less "professional". Thanks for any advice!
