Scott…
I am guessing you have some Yagis on top of that tower.
Like you there are many towers shorter than 1/4 WL long (including mine!) that
are shunt-fed.
Its the electrical length that matters. Top loading works.
It seems you didn't watch my video, since I actually show two images from
ON4UNs book referring to calculating electrical length.
So…yeh…I’ve seen his book.
