NM wiring does not make every outlet IG. IG requires two grounding conductors if the circuit is not a solo dedicated run.
One is for grounding for safety. The other is a dedicated ground that is not shared with any other circuit.
If you have a dedicated NM wire run you can argue that it is an isolated ground. But you cannot share that ground with any other circuit.
Details matter.
Also, you are allowed 360 degrees of bends in a conduit before you need a pull point.
Lastly, you are not allowed to pull sheathed cable through conduit except for above ground protection. IE, you can bury the wire all along the exterior route and then use a piece of Pvc pipe to come up out of the ground. But running it inside pvc pipe the entire run would require a a erious derate.
For ham use, it's arguably a stupid rule, but rules matter.
If you are going to run conduit the entire way then just buy 3 or 4 rolls of wire and make dipoles or radials with the leftovers.
Also, using romex style wire, stripped for individual conductors, isn't OK either. The ground inside a conduit has to be sheathed (solar get away with not following this depending on the jurisdiction)
The rules for electrical are so convoluted. While going through the apprenticeship one instructor told us that it wasn't his job to teach us how to wire anything, pull wire, install conduit, etc. It wqs his job to teach us how to go through the ecode book as quick as possible.
He was correct
