The ETS PV860 Series of NTSC Baseband Video Baluns are the original video balun for use in adapting baseband video to run over UTP. In comparison to our PV840 baluns, the PV860 offers potentially greater run lengths, depending on cable quality, due to careful impedance matching. Conversely, the frequency range of the PV860 is lower - the PV840 offers extended high-end frequency response for better synchronization.
