It really depends on what you are putting through the cable. You never mentioned what you're using it for . . .
Baseband video (NTSC, PAL or SECAM) is very forgiving of connections. I've used dozens on location without any visible loss at the final monitor.
HD-SDI, on the other hand, is very sensitive. I would not only minimize connections, but I would also pray a lot.
I have never wired for satellite, but I would suspect it to be finicky as well.
Cable should not be too sensitive, but it will depend on your cable provider. Digital cable should show no loss, until the signal degrades below the threshold of usability.
