>>But ON4UN also recommends linear loading AT THE BASE of a vertical
to be BETTER (less ohmic loss) than a loading coil at the base...?
Isnt that to the contrary of what you 2 wrote?

I wonder if it is more due to the difference in size of wire used in them
(ohmic loses), or sort of linear loading that is arranged in the way that
contributes to radiation.
I would use minimum coil or loading at the base just to match the impedance
to 50 ohms and do the loading as far away as possible from the feedpoint.
The final "judge" is the field strength measured.
