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

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.

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.

If you do not need a dummy load or a large meter, get this.

Versatile tuner can work with any antenna. Does not need external power (unless you want the adapter for the light) A little over ten inches wide and 3 inches high. Has selector for two coax antennas and can be switched to tuned or bypass. also has connection for external dummy load. I needed to download and print the instructions from the MFJ website at www.mfjenterprises.com/manuals

It takes a couple of minutes to get it calibrated but it is not difficult if you follow the proper procedure. Usually an acceptable SWR is close without even keying the mic and the carrier is only used to fine tune to its lowest point. Dont expect it to solve big antenna issues (using a metal broom handle on 20 meters) but it will resolve many out of band SWR issues. Remember that it is simply fooling and protecting the transceiver but not actually solving the antenna mismatch.

A VERY POPULAR TUNER WITH HAMS. MAX WATTAGE IS 300W AND KNOBS CAN BE A BIT TOUGH. GREAT FOR STANDARD WATTAGE RIGH (100) AND QRP.

I bought it in the hopes that come spring, and the snow is gone, Ill also get to put up my 80 to 10 meter antenna bought through Amazon. The antenna along with the tuner should prove to be a welcome addition to my shortwave radio shack.

This tuner has been excellent of tuning in my balanced and unbalanced antennas.

great

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.
