Jakobk Posted February 4, 2019 Report Share Posted February 4, 2019 What cable do you use for making proper tc cable? I have best results when using mic cable from a multicore I don't need any more. They work best on the lemo side but i struggle sometimes to get it nice on the bnc side. To solder the shield on the bnc shell works but doesn't look nice. Using a 50 Ohm bnc works well on that connector but sucks soldering on to the lemo 5pin... Best regards! Quote Link to comment Share on other sites More sharing options...
jason porter Posted February 4, 2019 Report Share Posted February 4, 2019 Try a BNC connector that is for rg174. Quote Link to comment Share on other sites More sharing options...
rich Posted February 4, 2019 Report Share Posted February 4, 2019 if you are using a BNC connector, then use the cable that fits it. as Jason said - if you are using an RG174 connector - which is what i use for most of my timecode cables, then use RG174 cable. its much easier when making the BNC as the connector and cable are designed to be compatible. get yourself a crimp tool for the BNC, as thats how they are designed to be made. i got a cheap Rolson one from Maplin whilst they were still going. hopefully you have something similar in Vienna you can get a hold of.

Jakobk Posted February 4, 2019 Author Report Share Posted February 4, 2019 Thanks for the great input! I have a crimp tool. Will check out rg174 Quote Link to comment Share on other sites More sharing options...
tourtelot Posted February 5, 2019 Report Share Posted February 5, 2019 Okay, struggling with co-ax for a Lemo to BNC is just silly. Get nice cable for the Lemo end (I use 22ga Belden Brilliance console wire) and simply use a solder-on BNC at the other end. I use these Calrad connectors. Easy-peesy! https://www.wallcoinc.com/Calrad_75_801G_75_High_Quality_Male_BNC_Connector_p/wal22-75-801g-75.htm D. Quote Link to comment Share on other sites More sharing options...
Matt Mayer Posted February 5, 2019 Report Share Posted February 5, 2019 Another good option would be to buy a pre-made BNC-BNC with a cable of the proper diameter for the Lemo5. Cut it in half, solder on the Lemo5, done. This way you can have nice molded strain relief BNC connections. Quote Link to comment Share on other sites More sharing options...

Derek H Posted February 8, 2019 Report Share Posted February 8, 2019 I think you mean what Matt Mayer said. I think the most important thing is getting the outer diameter of the cable correct to match the Lemo plug which can be ordered with different sized cable clamping parts to accommodate different sized cables. Buying premade BNCs and chopping them in half works great. The solder-on BNCs are also a good way to go. Quote Link to comment Share on other sites More sharing options...
Derek H Posted February 8, 2019 Report Share Posted February 8, 2019 I’ve used Canare GS—4 for TC cables with solder on BNCs. It’s a nice, not too thick unbalanced cable meant for instruments. Just a nice inner braided conductor and braided shield. There’s a plastic conductive layer you have to remember to trim though. The problem with using premade BNCs is if you’re not quick with the iron you get a lot of shrink back on the insulation which complicates things and usually creates a do-over on the Lemo end. Not as nice that way as a good Canare cable. Quote Link to comment Share on other sites More sharing options...
Philip Perkins Posted February 8, 2019 Report Share Posted February 8, 2019 You people making your own cables with Lemo connectors.....are better people than me. After years of struggle with the Lemo connections for my early wirelesses (Vega, Swintek) I decided to let folks such as yourselves make them for me, for which I pay handsomely.
