Compensation Network for Wide Bandwidth

Check this out and compare with others!


Special ferrite toroids manage reactance and provide the very high inductance values necessary in a 4:1 balun. The B4-2KX is a precision CURRENT balun, using two large, efficient, toroid cores, and heavy, high-voltage wire, along with special winding techniques. All this, combined with our exclusive, built-in L-C compensation networks achieves wide bandwidth, excellent output balance and a high power safety factor. It's an unbeatable combination. It's an unbeatable balun.
