I would have concern that long term usage of RG-8X, being foam core
dielectric material and bent in a tight radius, may allow the center
conductor to migrate to the inside radius of the bend. The Minimum Bend
Radius for RG-8X is 2.50". Thus the tight bend will allow the center
conductor to short to the shield. A solid core dielectric coax such as
RG-303 is much preferred.

I used RG8X coax, a 2.4" core, not sure exactly what mix, and 11 turns.
There is a *huge* variation in core materials and performance specifics found
in the FT241 form factor.
It really matters what the actual material is. On 160 the variation in the
balun could be performance anywhere between fairly decent
and amazingly pathetic.
