Default 100 Ohm Twin Lead

The antenna is resonant 100% by itself.


Most knowledgeable people know that the resonant frequency
of the antenna system can be changed by the length of the
transmission line series matching section. Why don't you
know that? Here is the SWR of my 130 foot dipole antenna
on 40m achieved by varying the length of the 450 ohm
transmission line.

Please look at that graph and then tell us that the feedline
cannot tune the antenna system to resonance.
