Do you mean "close to resonance" or close to 200ohm impedance ?
This is where the truly balanced matching units come into their own, but
does anyone make them?

Cobra Ultralite
(www.k1jek.com) and the other is a 40 meter inverted Vee fed with 300-ohm
twinlead. The tuner/balun has been able to match the first antenna on
160
to 10 and the second antenna on 40 to 10 (and even 80 but I never use it
there). The balun has always stayed in the 4 to 1 position. I try to
keep
Especially in the 4:1 configuration, this sort of configuration will only
work if the antenna is close to resonance. If the antenna is well off
resonance, the path of least resistance for the RF will through the balun
windings, which are a DC short, and will be an RF short if their reactance
is not greater than that of the antenna. Such a configuration may appear
to tune, but won't actually put much power into the antenna.
