Initially I was disappointed with this tuner, largely because of the lack of information from Yaesu, my main problems were getting it tune a random length wire across the bands, but after meticulous experimentation, I have concluded it favours shorter lengths, for example a 9M antenna length for me tunes from m with no gaps and no VSWR greater than 1.

IF I adjust the length to 9. So I conclude it is designed for mobile use and a reasonable length antenna for such. Overall I am now very pleased with it. I have never been able to get it to tune M, even with a 60M long wire. The problems I've found are due almost certainly because of the harmonic relationship between antenna impedance say between 80M and 40M, where the impedance variation can be huge, so the ATTU can tune a random length for 80M, but the same length on 40M represents a very high impedance, or vice-versa.

It is counter-intuative to shorten the antenna length when it is sold as a random length ATU! Conclusion use a short long wire I bought one of these units along with a FT, I have now sold it, as it just was awfal to try and get it to tune all the Hf bands, I installed it on my boat along with the using the backstay 7 meters and just could not get it to tune all the bands, So back went the Icom setup using a Icom AT see my report on the AT I even tried it at the home QTH and just had to give up!

You can take a lot of critical shots but this antenna tuner has given me great perrfromance ith my FTD transceiver. Build to work with the FT and FT, it does the job it was designed to do - my experience has been positive. I only need to use it on mm as I have a HF5B butternut bowtie beam for the upper bands. Did have an rf problem on 80m kept turning the TV in the shack on, but a few turns at the tuner end of the coax with a few ferrite beads did the trick. Have received great reports so far on the bands I have been on.

This tuner may not be for everyone but it works great at this QTH for what I need. This review will show you the option of using a dipole like antenna that from my experience works well with the FC I have now experimented with the tuner many hours using several different length sky hooks and an old style, single wire off-center fed Windom. Before buying the tuner, I read the eHam reviews which were very helpful. In all cases, I used five ' radials and a ground rod connected to the ground lug of the FC My first antenna, a sloping at about 40 degrees 66' wire up to the top of my 40' tower would not tune M, 40M, or 20M.

On twenty meters, I got excellent signal reports every bit as good as my Hytower which surprised me, but on 80M, I was well over an S-unit down from the Hytower. To extend the length of the 66' antenna to 85', a length some have had good luck with, I ran another 19' of wire at the 40' level towards another tower.

At 85', the FC would tune most of M, but signals were at least two to three S-units down from the Hytower. I tried 60M for the first time. It would not tune. And 20M would not tune. I extended the antenna to 96'. Now, M tuned better, but 80M, 60M, and 20M would not tune. Signals remained about the same as before. Today I put up an oldtime 66' Windom antenna strung between two 40' towers which you can find in older handbooks.

The impedance of a Windom is supposed to be around ohms, so I had my doubts if the FC would load it as VK7JJ found ohms and above to be values the FC couldn't handle, but I was able to load it on all bands except 80M and 60M. I have a 40' vertical wire coming down to the FC The windom is supposed to operate as a horizontal dipole on the fundamental frequency and even harmonics, in my case 40, 20, and Because a good ground and radials were suggested, I had my doubts about it being anything than a top loaded vertical, but antenna tests with a friend three miles away proved that the 40M polarization is indeed horizontal.

He has a Hytower and a 40M beam. Using my windom, my Hytower, his Hytower, and his beam in a series of tests, there was no doubt that the Windom was a horizontal dipole and not a top loaded vertical on 40M. I did not try to ascertain the polarization on 20 and 10 where it is also supposed to be horizontal. It is probably a toploaded vertical on the other bands. The Windom appeared to be a better antenna than the previous ones I had tried.

It loaded well on 10, 12, and 15M and probably will work well on those bands, but they were dead. Since the 66' Windom works well, I think I will try a ' Windom antenna next. At 40' height, it will be a cloud warmer on 80M, but should load up well there and probably equally well on the other bands described above with the 40M Windom. We'll see. In conclusion, the FC is a good end fed wire tuner for a random length wire, an inverted L, or a Windom, but you probably will not be able to find an antenna length that it will load on all bands without following VK7JJ's example.

Any single wire antenna needs a lot of radials to be a really good performer. No doubt, my FC antennas would have compared better to the Hytower on 80 and M if they had the Hytowers 40 radials. I see this happen on 80M especially with the antennas described above.

If I find any significant differences in a more virgin! Time Owned: 0 to 3 months. I agree with the thoughtful review of KA6GEM below, my experience is the same, it is an excellent product. I would like to add that I found I could significantly extend the usability of the FC by using a simple broadband step-up torroidal transformer which took only 20 minutes to construct 10 quadrifilar turns on a 2 inch torroid. I got the idea when I found I could not tune some lengths of longish wire inevitable of course.

I used my MFJB antenna analyser to examine the impedance of the wire at the feedpoint disconnect the FC and found it was high at around ohms or more when the FC had difficulty. When the 16x winding on the torroid was connected to the wire, the impedance as measured on the torroid primary was reduced and varied between typically 20 to ohms across all bands.

I found these values tunable by the FC and allowed my wire approx m to tune from m to 10m, with excellent signal reports. That worked a treat as well but of course a short vertical remains a very inefficient antenna. Two outstanding advantages of the FC are: 1 Removing the effect of the feedline both in regards to loss and unwanted impedance transformations. I can QSY as fast as I can push the buttons on my rig.

Time Owned: 3 to 6 months. In brief, I think it is a well-made tuner that installs easily, performs very well and is one of the best antenna options for portable operating. So here are some details about this new tuner for anyone interested. It is controlled by the base radio and activated by a single button. This design provides greater efficiency than one that tunes the coax as well as the antenna.

The tuner is housed in a heavy-duty plastic box sealed with screws. On the top is a wing nut porcelain post for the random wire and next to it the ground connection. On the bottom are two sleeve protected connection cables: one for the fifteen-foot 8-pin mini-DIN control cable 16 ft. Stainless steel hardware is included for a variety of different mounting installations.

I mounted mine on a 4-foot pipe sunk into the ground and substituted stainless wing nuts for easier install and removal. The installation instructions and hardware that comes with it provide for a set up in either a car, boat or on land.

The short 16 ft. Since I wired my shack with the control cable that accompanied the FC, I purchased an additional DIN control cable from the parts department of Yaesu and set it aside in my duffle bag for going portable. It is replacement part no.

This kind of extension cord is becoming hard to find as printer cables are now USB. So far, I have extended the control cable to a total of 60 feet with no loss in performance. Unlike the Icom AH-4, the control cable and coax connections are made outside the box eliminating the chance for water or dust to gain entry.

The FC instructions from Yaesu offer little advise on either the ground or the length of wire for the antenna. It is often recommended that the ground connection be of significantly greater mass than the wire used for the antenna so I used a one half inch wide braid grounding wire not supplied.

But I should add that my ground conditions this Spring, after a wet winter, are as close to perfect as I have ever seen. The red transmit light came on and within just a few seconds, the match was complete. Very nice! The label TUNR appears just below the The length of antenna wire is very important. The FC will tune through 6 meters as Yaesu claims but it is entirely dependant on the length of the wire.

I have found that inserting a insulator at about 50 feet and leaving the ends of the wires on each side stripped allows the option of simply connecting them or disconnecting them to work the meter band or perhaps the 60 meter band, etc. I tried various lengths of wire from about 30 feet to about feet, the upper limit at my QTH. At 37 feet, I could tune up on almost every band but the signal reports for the longer wavelength bands 80, 60, 40 etc.

As I increased the length of wire, I gained better performance on one band but lost on others. At about 85 feet, I received excellent reports on 40 meters, but then I could not tune on the 80 meter band as the length was too close to a half wave.
