There isn't a lot of information on making a pigtail for yourself, but I did find one site that helped. http://ddwireless.net/pigtail I'm making something similar to his second design. I have a BNC Female to Type N Male that will fit on my BNC cable (RG58, 50 ohm) but I am having problems understanding the SMA connector to put on the other end. Most SMA connectors used are RP-SMA, right (what I've been told)? So on that site he says to get a female and male SMA adaptor and put the pin from the male in to the female. Does this sound right? Will it then be able to connect to wireless adaptors that use SMA connections?
