We have put together a generic kit of 5 large 2.4″ ferrite rings for AC/DC line cords and 8 easy-to-use snap on beads (1/2″ hole) specifically chosen to be effective for the most common devices effected by AM Broadcast and VLF RFI in the range of 150 KHz to 10 Mhz.
Effective suppression for interference to alarm systems, audio equipment, phone and ethernet cables, computers and control systems, and commercial and consumer electronic devices.
Complete with instruction manual with installation pictures. If you can screw in a light bulb and follow instructions, you should have no problem installing the chokes on your effected 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.
