Cable techs are people too, and I've had enough experience with them to
say it's probably best to ignore anything they say.
I saw he was about to drill a hole in my brick wall from the outside
and stopped him.
He was trying to make a 200 foot run from one side of my house to the
other, the long way...because "it's not a good idea to use the crawl
space if you can avoid it" I didn't even ask why. I'm no engineer,
but I've seen many many houses with coax in the crawlspace. So I told
him "do not drill a new hole in my brick, if you can find one that's
already there, we can use that."
He looked around the foundation and said he'd take it in through the
crawlspace vent. I said "let's tap one bedrooms line, which is under
the house already, and run it to this other bedroom"
"I can't run it through the crawlspace..."
I took him in the house and told him where to put the receptacle, he
says "can't we just drill through the floor" Me, being a moron...said
"fine. I will put on some old clothes, then I will head down to the
crawl space, you feed me the wire and give me a tap and I'll make the
connection and attach it to your spade bit that you just ran through my
carpet and hardwood floor"
So, basically I paid the cable company $30 to send out a college kid on
a saturday to drill an unwanted hole in my floor (rather than putting
in a receptacle) and waste about 30 minutes of my morning because he
was afraid of the crawlspace or just didn't want to get down there.
He even gave me his flashlight and crimp tool before I went in.
Do it yourself, Quad shield is the best, rg6 is a little worse
shielding but is perfectly fine in my experience. Don't bother doing
it if you're gonna use that rg58 coax, it's cheap for a reason... not
nearly as good of shielding. And for pete's sake, never ever call the
cable company out and leave them unsupervised...I almost had a black
coax running all the way around my house about two feet up on beige
brick and a hole in my wall.
