Hi good afternoon,
The connectors are very important and beeing not Indian, I don't know which kind of connectors you can find in India on line.
Based on my experience (I am used to make cable by myself) the WBT are the best for signal cable
About soldering I suggest to buy from same brand as per attached picture
Please can you share the type of soldering machine that you are using?
I suggest also to use skrinkable protection (normally are black and red) to identify correctly wiers and connector form left to right
For WBT products there is a Chinese distributor: for what I know you should not pay more than 10 % of custom duty (to be verified)
In Italy I have alot of this connectors but unfortunately my next trip to Italy is at the end of June, so I cannot help you before end of July
Belden is a good cable
Regards
Paolo
