Generic Computer Equipment RFI Kits - use for desktop, laptop, DSL/cable modems, Ethernet, etc.
This RFI kit is specifically selected to cure most household computer device RFI problems. It contains 2 ferrite ring for AC or DC power supply protection and 8 Snap On ferrite 1/4" split beads selected to eliminate RFI from 1 to 300 MHz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
Useful for all brands of computer equipment.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.
