Ups, my bad. I forgot to mention that I want to use the same cable after I cancel my TV service and the phone also.
So in the end there will be only Internet on the coax. Now, in that case, can I use the same cable?
FYI, I've ordered the antenna. But I've tried so hard to find a data sheet online to figure out the antenna gain but no luck. I'll be needing that in case I'll use an amplifier. To do the math

. So is there a way to find that out?
And just for my curiosity, how come you've recommended this antenna when at the same time in the excel file from this thread (
http://forum.tvfool.com/showthread.php?t=109) you're saying: *Antenna Gain* "Get this value from the manufacturer's data sheet. If they won't provide this, you'll want to consider a vendor who will."
Don't worry I've done my research on the antenna and it's a great one, it has amazing reviews, so I don't doubt it, it's just that I was curious how were you able to spot this exception.
Thanks again
