HERE is an excellent loading coil chart I’ve used several times on both permanent setups and mobile setups.
Note however the chart doesn’t list for the middle MW band frequencies. It does list for the lower MW frequencies, either of which is not preferable anyway to the better performance of the upper MW frequencies.
Also to note about the small inductors and reason why I used them. In a case where portability and mobility is desired, compactness is easier to tote around than a bulky box with a large coil, and sits better on a typical music stand tripod (which is what I had on hand). The beefier setup was an experimental setup, later switched the coil out with one made from the linked chart.
Hope that relieves any confusion/conflict/whatever.
