Model CB-6-1500 is a 6:1 (300:50) voltage balun housed in a Nema enclosure box (4″ x 4″ x 2″) with two top studs capable of input power levels up to 1.5KW PEP/500 watts continuous when used with a matched load. The 6:1 ratio takes 50 ohms input and matches to 300 ohms balanced output from 1.8-61 MHz with SWR < 1.5:1 under matched load conditions. A great balun for windoms, OCF antennas >60 feet over ground, Hertz and folded dipole antennas, T2FD etc. Dual core, Ruthroff style balun. Choose version with side eye bolts for wire attachments for OCF dipole use.
Automotive Battery Charger RFI Kit - - 1-300 MHz RFI SuppressionProduct DetailsThis 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.
Simple - Effective and Low Cost solution.to suppress charger noise fed back into AC power lines acting as RFI transmitting antennas!
