Default Antenna / Choke Questions

Just ordered this 2m Slim Jim (http://www.jpole-antenna.com/shop/2-...m-jim-antenna/) along with 75ft of LMR400 to mount on the roof.

The instructions (http://www.jpole-antenna.com/wordpre...im-Antenna.pdf) show a choke that just looks like coax rolled up. Would anyone explain this to me? Also, how many coils should it be? Does that do the same thing a balun does?

Should I just get a kit like this: (http://palomar-engineers.com/1-1-balun-kits) to prevent losing distance on my coax? I'm thinking the 1/2" LMR400 is pretty stiff, so coiling it up might be a pain in the ass...
