Default fan w/sgc?

hi

I was wondering, if i designed a horizontal center fed dipole... w/a
sorta fan say a few legs for 10-40m... but

instead of just attaching coax, i attached a sgc tuner at the feed point

would i expect the dipole to resonate"" as one would predict if feed
directly via coax ex the 40m leg resonates on 40 or would the tuner
'grab' different ....??



tnx


naturally a single wire could be tune very well w/the remote sgc but
i ponder


If you were using the fan dipole with a tuner attached to the feed
point, the tuner would try to establish the best 50 ohm match from the
coax to the complex impedance presented by the antenna. The frequency
at which you are trying to tune, and the complex impedance of the fan
dipole at that frequency, will determine whether the tuner can match
the coax to the antenna. One particular wire of the fan could
dominate, but the tuner will try to match the overall impedance.
