No, continuous equals "zero" ohms and open equals infinity. I qualify the zero because there really is no such thing as zero resistance, only the top number of the scale (it reads backward). First off you should replace that crappy cable with something on the order of RG-213 which you can buy in pre made packaged lengths according to your need.
With that out of the way dig up some cable scraps and junk connectors and practice your soldering. You'll need the proper tools, thin solder of course, a small amount of rosin paste or liquid flux (don't trust the little bit in the solder core) and two soldering irons. For the heavy work like PL-259s a 100W industrial iron is best, one with a huge copper heat sink that won't go cool during the operation. Then a temperature controlled station with an assortment of tips for the light stuff like PC boards and components. Don't waste your money on a soldering gun, they're too hot for the small stuff and the little tiny tips go cold on the heavy stuff.
Now get this guys, I was professionally trained and the rule of thumb is if it takes more than one or two seconds to complete the job you're overheating the work and it is ruined. If your soldering iron goes cold you're using the wrong tool for the job and again ruining the work. Don't expect to get it right the first time, nobody ever did but practice does make perfection.
Now why did I choose that word? Because practice doesn't make perfect, practice makes mistakes.
Last but not least get a strip chart and assembly diagrams and learn how to properly prep the cable and assemble the connectors before you solder useless junk and find out you goofed the hard way and you try to take the mess apart again. The rule of thumb here is if you don't do it right the first time you'll have a booger of a time cleaning the used connector and toss it away in frustration. Even if it appears good it'll most likely crap out again being you overlooked a small solder blob or whisker, then it's "Oh no, it's shorted AGAIN???" Look down another thumb digit and you'll find Thumb Rule Subpart A: Cut it off and start again with a new connector.
