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

Good product, good ship time. Thank you

Good quality.A light but strong balun for home use or field day.

I have used several MFJ items and they are all quality items.

The UHF output was misaligned and fixing that isnt easy as you cant remove screws or take this thing apart in any reasonable way. However, performance of this balun is pretty good with multiple wire HF configurations.

Works as expected on an attic mounted OCF dipole. Though stuffing 135ft of wire into an average size attic doesnt happen without a fight, and the requisite SWR is pretty high on bands the antenna should be resonant on.

MFJ is good quality.Worked good on ocf antenna.

Works great feeding my 43 foot vertical antenna

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.

Prefect replacement for a previous balun! Working great!!!

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.
