3G HD SDI Video Cable on cable drum

50m + 2m 3G HD/SD SDI Professional Digital Video BNC to BNC Cable on Drum with Stand
50m of cable on the main drum can be deployed on location as required (up to 50m) and the the tail of the cable on a secondary spool can be accessed (up to 2m) to make a suitable connection. This is a system that I have used on countless live video set-up’s and found it to work very well.
All my cables are custom made by myself using care, experience and the right tools.
Cable: Argosy Image 360 LSOH HD digital Video Cable
Equivalent specification: Belden 1855ENH, Bryant Precision SDI Video Cables (Small) or DRAKA HD-Pro 0.6/2.8 AF HDTV
Connectors: Coax BC 55C3G
With the higher requirements of Serial Digital Video, HDTV, 3G etc., we now offer “true” 75 Ohm BNC connectors, 3G-SDI compatible BNC connectors. To achieve a nominal impedence of 75 Ohm, these connectors are designed with a reduced dielectric around the pin.
Complete with a matching rubber boot cable strain relief.

Image 360 Cable features & spec from web:
These coaxial cables are suitable for the transmission of serial digital video signals and are equivalent to Belden 1855 and Draka Image 360. They offer an advantage over traditional types of cable used for this application, as their smaller diameter allows a larger packing density in signal distribution systems, e.g. in jackfield and distribution amplifier wiring, where back planes are very densely populated. The jacket material used is LS0H copolymer for compliance with today’s increasingly stringent regulations for areas of public concourse.

Argosy Image 360, has a minimum bend radius of 51mm, thus using  circa 160mm to make a ‘U’ bend.
That is not to say that you can not impose a tighter bend then 51mm radius but if you do the cable will not deliver the stated bandwidth.
The cable is stiff compared to lower performance / bandwidth cables.
