IMO, construction of open-feeder line is worth the effort. I am using an
old stash of E.F. Johnson spreader insulators, but effective balanced line
can be made by using PVC tubing, with the ends sliced to insert soft copper
wire.

And my vote for the best "all purpose" HF antenna of all time. Nearly an
entire book on transmission line theory and antenna radiation behavior can
be learned just by understanding the mechanics of the W5DXP antenna.
