I've got a channel master in line amp for my dvb. From what I understand the card struggles to put out the need power to control my motor. I was wondering should I use the 13v or the 18v?

I have experimented with in-line amplifiers, my dish is about on the so-called limit, it has about a 90-foot run of cable going to it, and I’ve found that whether you put them on the LNB at the dish, or where the cable enters the house, or even on the back of the receiver they tend to add more noise than actually increase signal level any appreciable amount... now, keep in mind this was 15+ years ago with analog and Videocypher signals, but I would think, unless in-line amplifiers have gotten significantly better (and the ones I used were purportedly “the best” available at that time) you’d find the same results today.
The signal-to-noise ratio coming out of the LNB is the best it's ever going to be. No in-line amplifier, no matter how well designed, can ever improve that. It can only add noise. However, for long cable runs (+150 ft) or if you get stuck using RG-59 or low-grade RG6 pre-installed in your house for TV distro, an in-line amp can help alleviate further degradation of your signal.
Yeah, I was using it for the pc card. The amp is powered 18v and 13v plugins. Its not working like I hoped it would. I tested it first with my box before pluging it into the card. I lose motor control and it skews my signal

Best to avoid the amp altogether. With so much being powered by the receiver already (motor, LNBF), its just one more draw on the current... and one more thing to cause problems in the signal path.
