That is the design that I was originally going to use, except that I would change it slightly because I use all 75 ohm coax. Anyway, what is the advantage over one made with coax? Better bandwidth, I suppose?
Yes, the advantages of THHN are better bandwidth, and a closer Zo match to a high dipole. Jerry Sevick wrote about Zo of parallel wire line chokes, and had established the Zo values I noted. Many years later, I wound some chokes and confirmed these values within the range of experimental error.
