Interesting instructions. Looks like the "correct way" utilizes a 9:1
voltage balun between feed and antenna and a 1:1 current balun (called
isolator "AFI 5030" in the diagram) between other end of feed and the rig.

If the feeder is buried, (coax), then is the isolator required?

You may not need the isolator with the coax buried. There are to many
variables to know for sure such as the soil conductivity. Best bet is to
use one. You could also just clamp on some ferrite cores on the coax to
see if it makes a difference.

The diagram shows the antenna going back toward the house. This might be
OK if that part of the house is electrically quiet but if not you just
wasted your time with the work on the lead in. It would be better to
attach the antenna away from the house so the entire antenna is away
from noise sources.
