Mfj-911h switchable 1:1 or 4:1 balun


Trustpilot

The MFJ-911H is a true 1:1 or 4:1 current balun/unun designed for indoor use. It uses large low permeability ferrite cores to transform 200 or 50 ohm balanced or unbalanced loads to 50 ohms. It is rated at 300 watts with the relatively flat response from 1.8 to 30 MHz. Its SO-239 coax connector makes it easy to connect a coax cable. Two-way binding posts with standard spacing are provided for convenient hookup. A slide switch allows switching between 1:1 and 4:1

transformations. A current balun can reduce or eliminate stray RF often found on coax. This stray RF can cause

burns and other problems with electronic equipment while reducing antenna radiation.

Installation of an MFJ-911H balun can increase the efficiency of any amateur station.

INSTALLATION

1. The MFJ-911H is intended for applications

protected from the elements – out of the weather.

2. For use as a balun (balanced load to unbalanced)

connect the balanced feed line to the red binding

posts and the coaxial cable to the SO-239 coax

connector.

3. For use as a unun (unbalanced load to unbalanced),

install a jumper as indicated on the unit. Connect

the unbalanced feedline to the binding posts,

ensuring that the center conductor is connected

to the binding post that is not grounded and the

shield is connected to the grounded binding post. s.
