i don't know about w8ji's accuracy but it seems pretty clear to me what he is claiming,
he gives two examples of the no radial imax type antenna, first with a worst case scenario mast/feedline length and also with a best case scenario mast feedline length,
he is a little misleadin as he makes comparisons with his best effort 1/4wave model,

i don't have a problem with freespace plots as a level playing field for comparisons or when an antenna is very high above earth,

cebik wrote an interesting article on upper hf monopoles what he decriibes as "a poorly grounded speculation"
