Ferrite Slip On Bead, ID = .375in/9.5mm, OD = .687/17.45mm, height = .5/12.7mm, Mix 43 - excellent for small inductors using Mix 43 material or inductive compensation on outputs of baluns or ununs.or RFI suppression from 25-250 MHz
50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
