Old problem, need some additionally advices. I need to transform abt. 28 Ohm un-balanced ( 28.125 more precise ) in 1:4 ratio, or 112.5 Ohm balanced, to feed some folded dipole. What impedance should have WL / 2 loop itself ? Can I use standard 50 ohm cable to make the loop ? For 2m stacking. Tnx in advance, Edi, YO3HCV
