Because with the biomedical equipment we are testing - we prefer to have the minimal loss possible. And another reason I'm looking into this because we have some RG58, RG58AU, RG174, RG59 (75Ohm, which we don't need/can't use, but people still try to use), so I would like to keep everything to one type only, if possible, to avoid confusion. And since I'm getting this one type only, I would like to have the best one possible. > > The frequencies are anywhere between 5MHz and 500MHz. > > I'm looking at somewhere ~$400 for 500ft.

But, would I be able to use RG213 for both RF and data? Most of my signals are data. RF signal I currently have is 10Vp-p (0 to 80MHz), it could be greater voltage/frequency in the future. Thanks, Vitaliy
