328 ft SDI Siamese cable for 1080P video

This BZBGEAR BG-CAB-SDIS328 combines a 75-ohm shielded coaxial line with an 18-gauge stranded copper pair to carry 3G-SDI video up to 1080P60 alongside DC power or RS485 control signals. The 328 ft run supports 100m transmission distance for professional camera installations. Swept tested at 3Ghz to verify signal integrity.

Check BNC connectors and 75-ohm impedance match

Verify that both source and destination devices use standard BNC ports rated for 75-ohm SDI signals before ordering. The cable carries 1080P resolution at 60 Hz maximum, so 4K or higher frame-rate workflows will not be supported. Ensure your power supply voltage and current match the 18-gauge conductor capacity for the intended run length.

Siamese construction merges video

The integrated 2-conductor copper wire eliminates a separate power cable run for cameras or serial-controlled devices, reducing labour and conduit fill. Woven shielding rejects electromagnetic interference to keep images free from artifacts on long runs. The design suits both temporary event setups and permanent infrastructure where a single high-quality SDI link is required.

Questions about this item

Does the 328ft cable arrive with BNC connectors already fitted or must I crimp them myself?

The cable is supplied as a pre-made assembly with BNC connectors installed on both ends of the coaxial section, so no crimping tools are needed.

Should I choose a shorter run for 1080P60 or will the full 328ft still meet the 3GHz sweep specification?

The 328ft length is rated for 1080P at 60Hz and has passed 3GHz sweep testing, so the full distance meets the stated performance.

When the cable carries 1080P60 video over 100m, does the 18-gauge pair handle camera power and RS485 control simultaneously?

The Siamese construction includes a 2-conductor 18-gauge stranded copper pair that can carry DC power or RS232/485 signals alongside the video.
