We are having a TV antenna installed at the end of the month in our new house. Like an idiot, I didn't have the house pre-wired for this. The installer will take the coax from the antenna and run it to a central point in the basement.
For various reasons I pretty much HAVE to run the coax from the TVs through the basement/crawlspace. I have a rough idea where my reference points are down there, but I'd love to know if - for example - there are tricks that will allow me to drill DOWN into the wall plates to the basement rather than try and figure exactly where I need to drill UP. I hope this makes sense.
I'd appreciate any helpful hints.
