General question related to coaxial cable.

Hello,
I have just bought a new LG HDTV in it is being mounted in a room downstairs and I need to connect it to a coaxial cable, but my problem is that I can't drop cables through two storied of walls. I want to know whether I can connect it wireless. If yes, then what would be the best brand??

Thanks
