You might want to take a look at mini-UHF connectors. They come in male and female, are low profile and easy to install with the right crimper. The female is the third one down in this photo I took of different connectors I installed in my shop.
There is nothing wrong with crimp connectors, they work just as well (except for the center-pin type which don't work well), as soldered if done properly. I'm a pro and use both types all the time. Mouser sells a pretty good crimp kit
for a very good price $79. A little high for the casual user maybe but still a great price for what you get. I have all the expensive amphenol crimpers/dies $$$$ as well as this kit from Mouser. It's a good quality crimp/die kit.
