On the other hand, page 16 of the SGC-230 manual PDF specifically
shows a balanced dipole, being fed through "balanced line feeders,
300-600 ohms, up to 40 feet".
My 1990 manual shows nothing like that. Maybe they changed
their minds about balanced line feeders.
Could be... I was using a PDF copy of the manual I downloaded from the
SGC website. Possibly the newer versions of their couplers have more
flexibility in their tuning algorithm?
