Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.
Purpose. Model BA-4-1500DC is a 4:1 dual core balun kit (assembly required from parts supplied) used to translate a 50 ohm input up to 200 ohms at RF power levels up to 1000 watts when used with a matched load. It provides conversion from unbalanced coax to balanced ladder line/antenna feed point and gives a 4:1 impedance step-up to reduce SWR on the coax. Place at the junction of the balanced line and the coax to convert from balanced line to unbalanced coax.
KIT Contents. The kit consists of a 2 ferrite toroidal cores, two colors of insulated wire, a SO-239 UHF connector with stainless steel hardware, and an instruction manual.
Assembly time: About 1 hour, illustrated manual included with purchase.
Radio Club idea:
Buy 10 for a club do it yourself construction project - you can learn something and also build an end fed antenna (just add wire).
Product picture shows assembled item of all components in kit.
NOTE: for higher power and a true current balanced 4:1, use our BA-4-1500DC dual core 4;1 balun kit
