MFJ-941E MFJ941E MFJ Enterprises Original HF Antenna Tuner with Mini Cross Meter, 300 Watts

This is the second one of these that I have owned. The first one had issues with the plates in the capacitors arcing, and many of the screws on the SO239 connectors were loose. This one has no such issues. But while examining this one as you always want to do with any MFJ product, I found that the ISO239 for coax jack #1 had never seen any solder, and the ISO239 for the transmitter was a cold solder joint. This prompted me to clean the solder from all connectors and solder them again. The power meter is generous, but this is a minor detail. I love this unit and wouldnt hesitate to purchase another to work on as always. One thing I still plan to do is use heat shrink tubing on the wires tapped to the coil. Bare wires running close to one another has never been something Ive felt confortable seeing. Oh and Im not sure what the one person was talking about that said this has a yellowed light in the meter. I pulled it and looked. The unit I got has a bright white led which lights the meter bright and clear.

I am disappointed given the good reviews this tuner got. The wattmeter was not calibrated when arrived. it was off by about 20%. Isnt it supposed to have been done before it left the factory? Also, the reading differs by about 10% between 10m and 20m when the same power is used in both bands. I do not have a chance to try the tuning function yet.

After reading about issues with the inductor selector switch, that was the first thing I checked. Mine operates smoothly with positive detents. The antenna selector isnt as smooth. The meter backlight on the tuner I received is a nice white LED. It shows very nicely using a 5 volt power source and is really makes the meters easy to read at 12 volts. 80 through 10 meters tune nicely on my short compromise wire antenna. 10 meters is VERY sharp....patience is called for, but it will tune! My antenna is too short to get anywhere near a decent match on 160 meters. Overall, I really like this tuner so far.

Came fast and good package. It was a gift to my dad and he really like it.

Good product, I use it to tune multiband antennas

EXCELLENT

First one showed up doa. Returned item resold. Put off buying for a while but gave it one more chance. Glad I did itll tune every thing Ive thrown at it. Very happy.

Well, hams often say MFJ stands for Mighty Fine Junk and in this case they are right. The tuner is VERY twitchy when moving the knobs trying to tune different bands. My antenna is resonant on 20 and 40 meters, but other bands are hard to get right without a matching unit, which is why I got this tuner. My radio wont transmit if there is a mismatch greater than 3:1. Even though the MFJ says it has tuned to 1:1, the radio often sees SWR great than 3:1 and will shut off transmit. On some knob positions, when trying to tune, the needles pulse like theyre following a regular dance beat or something. This unit acts much worse than my older 945E which I moved to my QRP unit out in the shack. This was an open box return from Ham Radio Outlet, so I guess Im stuck with it. Going to open it up, clean it out and hope for the best.

I bought this as additional tuner to my MFJ971 which is a great little tuner. The 941E has a difficult time tuning everything the 971 does and IM not sure wise. I would not buy the 941E again.

Great product. Does everything it is advertised to do. Very happy with its performance
