Sonny, the feedline cannot and does not have any influence on the
resonance of an antenna. Resonance is determined by the physical
dimensions of the antenna itself.

Feedline length has every influence on the resonance of
an antenna system if the SWR is not 1:1.

Why is a G5RV resonant on 3.7 MHz when a 102 foot dipole
is resonant on 4.6 MHz?

Truth is that the feedline can be used to resonate the
antenna system. I resonate my 130 ft. dipole on any HF
band by varying the length of the feedline. Check it out
