MFJ Enterprises Original MFJ-913 Balun 4:1 Current 300 Watts

Simple device, works great, with a manual control antenna tuner I am able to get SWR in a range from 80 to 17 m with a 40 m wire dipole antenna in the attic.

product as expected. appears to be good quality.

MFJ is good quality.Worked good on ocf antenna.

Yes its not 1kw but for a 100w radio it works perfectly fine and being so lightweight it didnt drag my OCF down since i have no way to support from the feed point, only pulled tight from the ends. So for my needs it was perfect.

This MFJ-913 works great on my 80,40,20 OCF but only up to 40 meters. The swr is great at 80 and 40, just a touch of tuning is needed at 20. But now my feed line is radiating on 80 meters after only a week of having it up and is causing rfi in the house. Im only running up to 100 watts. Probably just a quality issue im guessing.

This will be used on a future antenna build.

It appears to work OK, and I did not have to return it for repair, if you know what I mean..

Great product and service

A very good 4:1 balun to match my 300 ohm balanced line feed.

As advertised.
