The effective electrical length of a MW monople radiator determines its

Now, returning to the diameter that has been proven to be necessary to
resonate this instance which you dismiss as "ridiculous examples," my
comment about seeing very few towers that exhibit this magnitude of
diameter (the size of my living room) still stands as unimpeached.

Going further into your cavalier dismissal of "ridiculous examples" we
find that there are a forest of very short antennas in service. My
link provides so many in one frequency assignment that the force of
numbers cannot be denied so simply, and certainly when lacking
technical rebuttal. Those offered such as WXNH 56.30° tall 540 kHz
when run through the same exercise above (YOUR reference, YOUR
claims) reveals a necessary A/D of LESS THAN 5. The simple math
resounds with the implications of necessary diameter to resonate this...

You have seized and fixated on a concept I did not generate, ie, that AM
broadcast antennas all need to be SELF-resonant, and that their L-D ratio
is the way to achieve that. Anyone referencing my statement quoted above in
this post, and thinking its does so has problems with reading comprehension.

Why don't you just accept this reality, and move on?
