I have good performance out of a sleeve antenna on vhf where the
sleeve was quite a bit larger tahn the coax running up the middle. RG
58 inside 1-1/4 inch sleeve. This was on a vertical antenna.

They are good antennas if decoupled. Many have been used for
commercial/public service systems. A company called "Dodge" ??
used to sell a lot of them. Real heavy duty construction.. Their
version used two stacked sleeves. You could also use stacked
radial sets.
