If I can add my $0.02 worth here... I have never found a better ferrite core for RX antenna transformers than the Amidon BN-73-202 (Fair-Rite 2873000202). I also used to use side-by-side stacked ferrite beads (eight FB-73-202 in two tight stacks of 4) to make "binocular cores", but that never worked as well. I immediately noticed an improvement in the performance of my Beverages when I switched to those little multi-aperture 2873000202 cores. Newark/Element 14 has those Fair-rite cores cheep.
