Product Details

This kit suppresses EMI and RFI generated from DC battery charger such as used on automotive batteries uo to 100 amps output.

Simple snap on the ferrite suppressors (1" hole size) onto the AC input using multiple turns through the center and do the same for the DC output cables. The more turns through the center the hiogher the RFI suppression.

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.
