The MFJ combines a versatile antenna tuner with an artificial ground. It turns a random wire into an effective antenna that works. You get a watt full featured, general purpose antenna tuner that covers 1. It has a two range, lighted Cross-Needle Meter that lets you read SWR, forward and reflected power all in a glance and a balun for balanced lines.
It tunes all types of antennas and feedlines including random wire, coax and balanced lines. The MFJ is unique because it has a built-in artificial ground. A ground matching knob lets you switch in inductance to bring an attached wire to a low impedance current point to form an artificial ground. A push button lets you use the cross-Needle Meter to monitor for maximum ground current. With an artificial ground to work against, youll be surprised to see how well a random wire can work.
Dont be surprised if you can work the world without hours of calling CQ. When you dont need the artificial ground feature, you can use the MFJ as a full featured tuner.

MFJ - 1. Got swr down to close to Lowered power. Made over 20 contacts in about an hour. I don't understand why more antenna challenged folks don't give this box a chance. Write to me if interested. Time Owned: 0 to 3 months. It's slow and manual but the feeling I get having such a very low SWR compared to the other two is worth it.
Plus, it's perfect for the campsite where power is limited as this needs no power supply except for the meter illumination. I live in a condo and use a 30' 22 Gage wire antenna deployed out the window into a palm tree with a variable length counterpoise in the shack. The tunes meters appropriately as does the MFJ and I have had issues with RFI in the shack especially the computer. I do a lot of digital modes. However, it was necessary to adjust a cover screw that was shorting out the Ground Matching inductor prior to getting the inductance working.
This is a new unit right out of the box manufactured this year. Now works great! Wish I had gotten it sooner. The 5 is for performance. Great tuner. Artificial ground is really functionel. It tunes my FT D smoothly at full W. Antenna is a 30 ft. Works great on all HF bands and even on 6 m. No bad surprises, no electrical arks or any other botherings. I would recommend it. I have owned the MFJ unit for 18 months.
When received it did not function properly. I took the top cover off and again tried the tuner. It worked. That was a major clue about what was wrong. The two inductors were not level. They should be evenly spaced between the case bottom and case top, A straightedge across the top, front to back, confirmed that the inductors would short out against the case. Now the MFJ works flawlessly. Had I not had a DOA unit on arrival, the rating would be a 5. I have owned this unit which looks different from the illustration on this page for about a year.
I returned it to MFJ, who promised me quick turnaround because it was such a new order. I never experienced any RF in the shack that I recognized, anyway…new ham, remember, and I was only using CW, not brushing my lip against a mic. I have no trouble tuning up to 1. I get no response at all anymore from the artificial ground adjustment…nothing. Could be my excellent antenna systems?
Glenn K7GLE. I bought this tuner after I could not tune my attic dipole on several bands with the autotuner built into my transceiver. It tunes the dipole well, but I had even better results with a 70 ft random wire and several counterpoise wires running around the room and out of the window. With this setup I was able to contact 12 DX countries on 3 continents within 2 days there was a contest on using only watts.
After this positive experience, I installed a 50 ft random wire antenna on the top of my rv in a v-shape. It is attached to the ladder and roof rack with dog bone insulators and nylon rope, and to a 15 in long PVC pipe standoff in front With this setup I so far made contacts as far away as Maine and Aruba on 40m and 20m. I did not get the RV setup to tune on 10m, 12m or m, but I hardly ever use those bands anyway. Overall this is an outstanding piece of equipment for wire antenna fans like me.
It is a great value for the money. My only gripe minor is that it has "hand capacitance", meaning the SWR changes when I touch the tuning knob, which can make it a little tricky to tune on some bands. Also, I wished they would make a higher end version of it with higher power handling, so that I could use an amplifier for my base station.
I bought this unit because my shack is on the 2nd floor of our house The tuner performs well. I am able to tune my ' dipole on all bands, M at W with no arcing or other problems.
