I have researching home brewed baluns and have a question that I can't seem to find an answer for. As far as 1:1 current baluns go, I have seen bifilar and trifilar wound designs. Are there advantages/disadvantages to either design? Err.... I guess I may have had a senior moment. The trifilar...

You are correct about using an acid based flux but there are MANY solders that contain 2 or 3% silver and have a rosin core. ester makes it among several others. i'm talking about regular tin/lead/silver solder and not the Silfoss type of bronze "solder" that requires a torch. It is great for RF...

Agreed. What I had to do when soldering was take a small jewelers file and and file away the nickle plating and solder to the brass or use good silver bearing solder as it will adhere to the nickel. All the silver bearing solders I have seen use an acid based flux (zinc chloride) which...

Oh yeah, I never even thought about the solderability. Both of these connectors are the solder type. But then again I could easily sand the plating off where I will make the solder connections, but that would be an additional step. As far as corrosion goes, they both have brass as the base...
