Topband: Silver solder

[Tom W8JI]

Jorge,

You do not need or want a high silver content. It will be too brittle.

What you should ask for is a solder that has high tensile strength, is 
ductile, and works well with copper or whatever your radials are.

That will not be a high silver content. It will probably be less than 8% 
silver with high tin content.

Higher temperature is supposedly good for resistance to lightning, although 
I never had a joint unsolder even when regular electronics 60/40 soldered.
