Coax cable is available in a wide range of types, and for the small increment involved (if any) it makes sense to get the right stuff for your boat, and the best quality can. The higher performing cables are larger in OD, so this might be the main issue.
Be particularly careful of low end coax (RG6 or RG59) that would be used for CATV applications. Not only is it the wrong impedence but often the shielding is really minimal, and what braid there is may be aluminum and difficult to solder. You need to make sure the jacket is UV resistant for the short length exposed, or just cover it with heatshrink. Look for a high copper braid shield coverage, expressed in %, and ideally an indication that the coax complies with a mil spec. "Marine Grade" is total bullship, A ham radio place will be a better supplier than a marine dealer, and you can guarantee (almost) that the folks know their stuff. They can sell you quality connectors and will probably solder them for you if you want. Here is a simplistic but adequate overview of 50 ohm coax, RG 58, RG8, RG 213 http://www.westmarine.com/WestAdvisor/Coaxial-Cable Get a bit extra and you can make yourself a "slim jim" style emergency VHF antenna for a few dollars. Google it. I am using Belden 8267 (RG-213) Belden a manufacturer that is historically identified as an industry standard - their part numbers are often used as generic descriptors.
