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.
Try looking through this "catalog" of chokes:

of chokes on his main page at http://k9yc.com/publish.htm
