Exterior Hose Bib question

I would like to replace an exterior hose bib with a ball valve,quarter turn replacement. The replacement has male threads that would be attached to my 1/2" copper line.
A couple of questions:
How do I sweat the male threaded bib to the copper? Should I attach a female threaded cooper adapter to my line and just screw it on or should I sweat the threaded male brass to a female copper and then sweat it to my 1/2" copper line?

Also,I have to install the hose bib sideways because the deck would not allow room enough to attach a hose in the normal way. Is this common practice?

Thanks in advance.

sweat on a female threaded elbow and then screw the hose faucet into it.

If this is exposed to the outside, in Connecticut it should be a frost free valve and it will not drain if turned sideways. If it is not frost free, it should have a shut off inside so the bib can drain in the winter. It can be turned as desired, but the pipe needs to have a slight downward slope.

Thanks for the quick responses.

I do have a shut off inside and the 1/2" line does have a slight drop to it.
I can't say that about the other faucets,but this one does and right now it is my main concern as I have a project going on.Thanks again!
