I did wind up a 1:9 balun for this few days ago, even though I still do not own a MLA-30. However, further work is pending on this toroid part as I dont know which connector(s) to fit in on the box. And getting those connectors matching MLA-30 is a big challenge.

I also asked copper tube technicians to bend a 12mm soft copper tube to a round loop. (Indians hardly like to do anything on their own by the way, and I am being very frank here.). I am even looking for a readymade 1:9 balun if available. Mumbai market has none. They have nothing for RF hobbies, nothing on RF, no baluns, no Pots, no connectors to radio sets. All they now have is latest stuff HD Video, CCTV stuff.

Couple of reviews on MLA 30 experimenters group on FB indicate that their MW was reception was boosted on their tube sets when using this loop.
