I have been researching the inverted L for 160, and have received much
helpful information. - Thanks!

Today I stumbled across a document regarding the 1/2 wave inverted L.

Has anyone done a side-by-side comparison?

I have modeled it and the results are predictable.  About
half your power goes into likely useless horizontally
polarized radiation.  If you instead make a top loaded
("T" type) vertical where the sum of the height and half
the top wire is a half wave, then you get a "voltage fed"
vertical that behaves pretty much like a half wave
vertical.  Since the drive impedance is high, you MIGHT
get away with a much less extensive counterpoise.
There is some controversy about this.
