Rods have rough finish. All packed together without separation, so arrived broken. Contacted seller but no response after a week. Q factor on MW frequencies is 30 - 40% lower compared to noname rods of the same shape bought elsewhere.
Rods with 12 mm diameter have rough finish, shape is not circular and different to those with 10 mm diameter. Measurements for 10 mm rods have shown reduced Q, they are not the best for radio applications
