Snap On Sleeve Chokes
Connector already on the cable? Don’t want to remove it? Use Snap On Ferrite split bead kits that clamp over the cable.
SNAP ON Sizes for Heliax and Coax Cable
Shown in the table are the SLIP ON and SNAP ON products for various popular Heliax and coax cables. These are the correct size for making common mode chokes for coaxial cable using either Snap On ferrite beads.
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.
