John, you'll probably be using something like RG58, which is actually too thin to fit standard SO239/PL259 connections. They are made for thicker RG8 coax but there are different versions to fit the thinner cable. Make sure your cable and fittings are matched!
In any case, none of those are crimped. Crimps are for cableTV and similar coax, they aren't used with VHF. You either solder, or use compression fittings. (Plenty of coaching on both online.) Either way will work if you do it right. I'd suggest you buy a couple of extra fittings and an extra foot or two of cable so you can cut it shorter & try again if the fitting isn't right.
Take the time to make good connections and buy premium cable. Stress-relieve it, use silicon grease in the fittings, use "coax wrap" or butyl or silion tape over it, to keep water out. The little things like that are going to push up your cost and double the time it takes--but they'll also double or triple the life you get out of the job.
