biferi,
There's a method of making connections for a PL-259 (male part) or an SO-239 (female part) and coaxial cable. Connecting to either connector requires soldering for a really good connection, but there are 'crimp-on' PL-259 connectors, no 'crimp-on' SO-239 connectors that I'm aware of. Still need a special tool for that 'crimping', though.
Who says you are going about it the wrong way, and why?
