Ferrite Material FeNiCu is not a best specification for use on VHF / UHF as Materials 43 or 61 from NiZn show higher Impedance per size ... but it is sufficient even for demanding applications:


A single size 1 High Flux Core was used by the V31EME DXpedition (DG8NCO) on a 432 MHz 25 el. Yagi lasting 3 moon paths with 0.9 kW in WSJT enabling even a CW EME QSO with this single Yagi.



Size 1 and 2 cores fit nicely on Cellflex LCF 12-50
(15.8 mm coax to 15.9 mm core inner diameter)

Size 1 and 2 on H2010 (10.3 mm coax)



These are surplus cores with material analysis but no other then the above
specification available. Plus plotted S11 Reflection in dB see here
