Alvin's Cables RG179 Blackmagic HD/SDI Coax BNC Male to Male Right-Angle Cable (30CM)
Product description
The essentials
If you’re wiring a Blackmagic BMCC setup and you want something that’s easier to route than thicker coax, this Alvin’s Cables Blackmagic RG179 HD/SDI lead is designed for the job. It’s a flexible, thin 75 Ohm 3G HD SDI coax cable fitted with right-angle BNC male connectors on both ends, so it’s built for tighter spaces where straight connectors can get in the way.
On paper, it hits the practical requirements most people have with BMCC cabling: correct 75 Ohm coax type for SDI workflows, a short length for clean internal runs, and right-angle terminations to help with strain and cable management. Still, it’s only 30CM—so if your rig layout needs more reach, you may want to look for another length rather than forcing a route that’s too tight.
What you’ll notice day to day
The RG179 coax approach is all about flexibility. In real-world rig builds, that usually matters more than you’d think: you can tuck the cable behind small camera cages, route it around monitor supports, or avoid sharp bends that make bulky leads feel awkward. The right-angle BNC male connectors are also a welcome detail—especially when the camera’s I/O sits close to rails, plates, or other accessories.
A small but important promise in the listing is that the cables are tested before shipping (including checks for short circuit and potential breakdown issues). That’s not the same as extensive real-world stress testing, but it does reduce the “will it work out of the box?” worry.
Here’s a micro example: if you mount your BMCC on a compact rig and the SDI port is near a side plate, a straight BNC can demand extra clearance. With right-angle connectors, you can typically route the cable neatly alongside the rig instead of fighting for space.
Key points
This cable is aimed at short, tidy HD/SDI connections for a BMCC-style setup. It’s a 3G HD SDI coax lead with a 75 Ohm specification and right-angle BNC male to right-angle BNC male connections, using a flexible RG179 coax design.
Because it’s thin and flexible, it’s easier to manage in cramped builds. But you should also consider length carefully: 30CM is great for compact rigs, yet it can feel restrictive if your camera and recorder/display are spaced further apart.

Where it shines (and where it may fall short)
Where it shines is clear: short-form SDI routing, flexible handling, and right-angle BNC terminations to keep builds cleaner. If your current cable is too stiff, struggles in tight spaces, or you’re simply trying to avoid awkward connector interference, this is the sort of cable that tends to make daily setup easier.
It may not be the best fit if you need more than 30CM, or if your build involves long runs that will be under constant tugging—flexibility helps, but the length still limits how neatly you can route. Also, because this is specifically positioned for Blackmagic BMCC video camera use in the description, it’s sensible to double-check that your recorder/monitor expects the same kind of SDI connection and coax setup.
Should you buy it?
It’s worth buying if you have a compact BMCC rig and you want a flexible RG179 75 Ohm HD/SDI cable with right-angle BNC male connectors on both ends, and 30CM matches your run length.
You may want to skip it if you’re dealing with a longer distance between devices, or you prefer a straight-connector layout that suits your current setup better.
It makes the most sense for shooters doing everyday field builds, small studio rigs, and quick camera-to-monitor/recorder wiring where cable management genuinely matters. If you’re unsure on placement, measure first—30CM can be either perfect or frustrating depending on your cage, rails, and where the SDI equipment sits.
Mini FAQ
Does this cable suit a Blackmagic BMCC SDI connection?
The description is specifically for Blackmagic BMCC video camera use, so if your workflow matches that SDI setup, it should be aligned with what you’re building.
Is it right-angle BNC on both ends?
Yes. Both connectors are right-angle BNC male to right-angle BNC male.
How long is it?
It’s 30CM long.
Is it tested before shipping?
The listing states every cable is tested before shipping to ensure there are no short circuit and no potential breakdown problems.
Can the length be customised?
The listing says cables can be customised with other lengths, if you need something different.
