All of my radials are crimped lugs bolted to a common ring at the base of
my antenna (either a stainless plate, or a piece of copper strapping)
Copper strapping can be bought with pre-punched holes, or punched by hand
with a Roper Whitney (or similar) hand punch.
All booked connections coated with conductive anti-oxidant.
I buy lugs from T&B, usually in bulk on eBay. Be sure to get the right size
for your wire, and invest a little in a proper crimping tool.

> FLUX SELECTION:
> 1. Pure rosin. Hardest to work with, but minimum
> corrosion issues.
> 2. Activated rosin. Easier to work with. What
> corrosion issues are there?
> 3. Acid core plumber's flux. Very easy to work
> with, very corrosive. Does this hold up in the
> rain, etc?
