It's not tricky if you have three things:
1) The right soldering iron. I have a Weller W100P that I use for this. It's
also handy
for copper tubing and strap in tank circuits, etc. It has a large thermal mass
so that the
heat is transferred to the connector quickly, and is also temperature
controlled.
2) Decent connectors. You need these anyway! I have some that I inherited that
solder
doesn't stick to.
3) Decent coax, with good braid coverage. Again, you need this anyway.
