The balun I was using on my TGM Communications MQ-26 miniquad died a couple of months ago. I came up with the idea today of making one myself since I have some extra RG58 I salvaged from a mobile antenna mount. I plan on running some turns of it on a FT240-31 ring torrid. Maybe 2 rings, one on top of the other. I need it to cover 14-50mhz. Any good idea as to how many turns through the ring I need?

I have found some plans using a FT140-43 torrid but that looks pretty small to work with.
