I have a wire dipole and an inverted Vee each cut to resonance on a
desired frequency. I would like to add a reflector and/or a director
(one at the time) to make each one a beam. Will adding the reflector
and/or director change the resonant frequency, or just the impedance?

Thanks

Maybe I used the wrong word, 'resonance', but I was referring to the
lowest SWR match, which I would assume for the example to be less than
1.5:1 on a given frequency.

To be more specific, assume a 20 meter inverted vee trimmed to minimum
SWR at 14.225. Would adding the reflector, and then the director
(assuming I match the coax tot he antenna impedance) raise or lower
the tuned frequency of the antenna?
