MFJ-919 Balun 4:1 Current 1500W

The MFJ-919 is a high-performance antenna center insulator that functions as a true current balun with a power handling capacity of 1500 watts. This device is engineered to transform 200 ohms to 50 ohms, and its transmission line transformer construction, utilizing 100 ohm characteristic impedance transmission line, ensures a flat response from 160 to 10 meters.

Built with large, low permeability ferrite cores, the MFJ-919 is able to withstand full power, while its SO-239 connector and stainless steel hardware provide reliable and durable connections. The device also features a direct 14 gauge stranded copper wire connection to the antenna, and is housed in a heavy-duty weatherproof enclosure. Measuring 3½ x 3½ x 2½ inches, this compact and efficient device is an excellent choice for optimizing your antenna's performance.
