MFJ-913 4:1 Current Balun
1.8 to 30 MHz - 300 Watts - 200 Ohms Balanced to 50 Ohms Unbalanced
The MFJ-913 is a high-performance antenna center insulator that can handle up to 300 watts of power. With its true current balun technology, it can transform 200 ohms to 50 ohms for optimal transmission. The transmission line transformer construction, using 100 ohm characteristic impedance transmission line, delivers a flat 160-10 meter response. The device also features large, low permeability ferrite cores, SO-239, stainless steel hardware, and a direct 14-gauge stranded copper wire connection to the antenna. With its heavy-duty weather housing and compact 4¼ x 2 inch diameter, the MFJ-913 is a reliable and efficient solution for all your antenna needs.
