Here is a link to the RCA connectors I purchased. This is the Mini Coaxial Cable I am using. I have all the crimping tools for terminating RG6/RG59 and have had plenty of practice doing it over the past year.

Mostly I just need the length of how I should cut the conductor and outside sheath to.

Mini-coax cable (not RG59) typically terminates with BNC connectors. I doubt you'll find a RCA crimp connector for that size of cable (it may be out there). If you need RCA, you'd terminate with BNC and then use a BNC to RCA adaptor.

My bad. Beldon makes a crimp on...part number HC2910A. The crimping tool is a bit pricey however.

Thanks for the info. I guess there is no type of guide out there about the length the cables should be cut.

I have used Liberty multiconductor cable, which has worked very well for me (Solid 23 AWG RGBHV COMPOSITE CABLE - NON-PLENUM). The product shown on that link isn't exactly the same as what I have used in the past, but I got my cable a couple of years ago and they have changed the lineup slightly. This cable uses a 3-piece connector to make an RCA end out of the cable. I have used it to make component, composite, and S-video (using an adapter cable), and it offers flawless performance when terminated correctly.

The cable is not easy or intuitive to terminate (like standard RG6), and it is only because of my work with home theater installers that I learned how to terminate it myself (trained in person with a Liberty rep).

The cable requires a special stripper that strips the mini cable in sections, along with a crimper specifically designed to work with mini coax. I don't know if it's possible to terminate mini coax using standard RCA fittings, but I've never used a different brand of cable. The mini-coax fittings have a smaller opening, and they are designed to work with the gold-plated pin that is used with the Liberty cables. I could be wrong, but I'm not sure if you can easily mix & match mini cables and standard ends (and expect to get proper performance/fit).

With all of that said, I'll add that I'm not an expert on anything besides the Liberty brand, so take my comments with that in mind.

Hi curtis104
Did you get it done yet.
I'm in the same situation as you now trying to run mini coax component cable for HDTV.
If you did, can you give me some guidance please.
Thanks

There's no reason you can't just use solder on RCA connectors. That's what I do with mini coax. Even at analog HDTV frequencies, the impedance mismatch is not significant. Plus, most RCA connectors are not 75 ohm anyway. Canare makes a 75 ohm crimp connector but it's for RG59 cable.

They make crimp connections for mini coax too.

Yes, they make BNC, but RCA as well?

There are a bunch of companies that offer RCA's in all different cable gauges. We use Liberty cable/connectors where I work. Termination is the same as any type of coax cable. 1/4" x 1/4" sheath and center conductor. You don't need special strippers for them either. You can find strippers that'll work at Home Depot if you need to. The grey ones with the orange removable center work fine, and they're cheap. You just have to calibrate for whatever type of cable you're using. If you're good you could also just use a razor blade to strip the cable. Fold back the braid, insert the connector, and crimp.

Also, make sure you get connectors that are made for the solid-core conductor. Some cable manufacturers have stranded center conductors which usually use a completely different type of connector.

RCAP-3CA and RCAP-3CF, if I'm not mistaken.

Why not use the compression RCA ends instead of crimp on ends? They seem to be better quality.

I have yet to see a compression RCA that competes with the quality of the Canare crimp-on ends.

Those mini cables are a neat way to make many rca's and keep them nice and tidy and together...cool..
