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.
Icom PS-125 Generic Power Supply RFI/Noise Reduction Filter Kit for Short DC CablesProduct DetailsMPN: RFI-ICOM-PS125Type: NEWCountry/Region of Manufacture: United StatesFilter Power Rating (PEP watts): n/aRFI Suppression Range (MHz): 150 KHz - 10 MHz# Ferrite Filters: 4Typical Use:: SMPS common mode noise suppressionThe RFI-ICOM-PS125 is a common mode noise reduction filter set which filters both the AC input and DC output of common SMPS power supplies. These filters effectively isolate the AC power cord and DC output cable from acting as antennas for the internal switching power supply generated noise. The mix 75 filters suppress RFI fundamental frequencies (and the harmonics also) from 150 KHz to 10 MHz. Simple to install on cables without any device modification.
Since the 12 Volt DC cord is very short, we use simple snap on ferrite filters for the DC cable, and a ring filter for the AC power line filter.
Used for amateur and commercial radio transceiver power supplies, cable TV boxes, laptop computers, or any electronic device powered by an external switching power supply.
