Chuck, thanks for that information. I wonder if anybody knows if those 0.61" ID would somehow fit LDF4-50A? I figured the next ones in ID are 0.75"! And is it OK to use short toroids instead of beads

I guess it also depends on what antennas you have on the tower. If just one monobander then it would be fairly easy to find nonresonant leghts of EHS guy wires with modelling. But if tribanders etc..
