The choke is now wound, the PL259 plug is fitted, and the top of the plug where it meets the cable has had a small amount of Sugru applied to it.
On doing a Google search for "PL259 plugs and Sugru" it turns out that there is no record of anyone doing this which means either one of two things, I am the first person in the world to watertight the cable entry of a PL259 plug with Sugru or others have before me and not really made it public
The RG58 I used is reasonably good quality, it has good braid coverage and a good dielectric, I just now need to measure from the choke to the point in which I will be cutting off the braid, I then need to measure from that point to what will be the top of the antenna (so 8.5ft and another 9ft respectively as per 26CTX104's YouTube video, the 9ft top section allows for some tuning down, folded over and not cut as the VSWR may vary from location to location)
So I look forward to getting the next bit done, then perhaps this antenna will be up and I'll be on air soon :)
