Signal Strength: Coaxial Cable and Eye-Connectors

[Junaid Ahmed]

Hi

My question is related to Video Signal Loss. Ok.. I elaborate the senario. There is a camera in the studio (Sony PD70), I am taking its DV out and converting it to SDI with the help of DV bridge installaed in the tripod. This SDI signal is running through a coaxial cable which is approx. 30 meters long to the video mixer. This cable is in three pieces and joined by eye-connectors. Please let me know how much SDI signal is lost from camera to the mixer?

OR

In other words how much signal is lost with the induction of eye-connector?

Thanks in advance.
