Not sure what SGC recommends regarding balanced antennas.... will
review their info. However, I have read numerous reports from hams who
have used SGC and other similar tuners to feed balanced lines. The only
important condition was to use a choke balun to keep RF from coming back
down the coax shield.

My SG-230 manual says NOT to connect any transmission
line to the tuner output - to connect only an antenna.
