Can't beat this little tuner!  Time owned: more than 12 months
I have had this gem in my arsenal for almost 4 yrs now. About the only time I used it was for field day or when testing a new wire antenna I built.
Well 2 weeks ago, my wife and I took our daughter to the airport so she could report back for duty at Ft. Leonard Wood. Came home, found out we had had a short term power outage, when the power came back on, it trip something inside my 6 month old FT-897D, and the little battery lights were blinking. Long story short, wound up sending the 897 to Ca. for repairs.
Figured that I needed something in the front room to keep me happy, (see my bio, on my lazee boy HF station). So I brought out my trusty FT-817ND hooked my Dentron Jr. to my 67' Windom and I was back on the air! Although, I'm only running 5 watts, this tuner WILL tune from 40 on up through 6mtrs. including 10 and 6 meter FM. So yea, this little tuner that was GIVEN to me is staying in the shack. I do have the MFJ 949E which is hooked to my Kenwood TS480HX, I think I'll just leave my lazee boy QRP station up and running the way it is for now. Can't beat this little Dentron Jr. Monitor! Looks like it's going to get a LOT more use!

Rugged compact simple medium power tuner!  Time owned: more than 12 months
I've owned this little gem for about 3 years, now, and it still performs like new - and it was several years old when I bought it off ebay.

I take it with me when operating HF portable to tune my portable rotatable center fed mid-loaded doublet. Electrically, the doublet is a half-wave dipole for 30M, but about 24 feet long physically. The tuner tunes this antenna on 40M to 10M with NO problem at full power (100 watts). And, the tuner is rated for up to 300 watts.

It has both coaxial and balanced outputs (in parallel, not switched), and will tune long wires.

The built in meter is handy for determining relative SWR and power output - just tune for max deflection on the meter at whatever power level you choose (there's a calibration control on the back). When power output is max, SWR is minimum.

My other tuners are a Heathkit SA-2060 and a Heathkit SA-2040. This one stacks up well against the others when portability becomes an issue.

Yes, I'd buy another one.

A great Tuner  Time owned: 6 to 12 months
I got mine off e-bay, for good price. Well built unit. I've used it for random wires and dipoles. Used a MFJ 941E before getting the Dentron. The MFJ arced on 40mtrs and 80mtrs at full output(100w rig), but the Dentron does not. The output meter is relative and I use inline watt/swr meter to tune with. I'm sure it will serve me well for a long time. This one is staying with me!

Good basic tuner  Time owned: more than 12 months
I had one of these for a little while in the mid 1990s. Tuned up things ok, but I never could figure out how to read the reflected power meter that came built into it. I don't think it had an antenna switch on it, but I could be wrong.

Great little tuner  Time owned: more than 12 months
I have had this little jewel for about 5 years an use it out camping an have it mounted in my Honda CRV for mobile use. I captured mine for about $40 bucks an will most likely have for several more years. Really works great an is very small so you have more room for more radio gear. If you find one get it, you will like it. Thanks Tom KG4HUP

The Mouse that Roared  Time owned: more than 12 months
I have enjoyed my Dentron Jr. tuner for several years, it's what I take with me when I go camping and have used it to tune my IC-706IIG into a 1/4 wave wire slung into the canopy of trees overhead.

It seems to be able to tune everything hooked to it.

Acts like my Dentron MT-3000 with regard to tuning procedure.

One trip to a No.Cal campsite, wire thrown into the trees overhead, received a '25-over-9' signal report from W6OBB in Pahrump,Nv utilizing this diminutive but smooth-as-silk tuner behind my 100w FT-100D.

I've also successfully run 450w pep after tuning with 50w through the Jr.

I have the specs and paperwork but won't share it with someone only giving a '3' to a '5' tuner!

The only drawback I've found is the relative meter reads too low on some bands and too high on others, I use the swr meter in the rig for tuning.

Just a great and solid little tuner! 73

26 years and counting  Time owned: more than 12 months
I bought one of these 26 years ago, and its still in daily use. I've used it portable, mobile, and fixed in all kinds of situations and for all kinds of antennas. They work great, and obviously, they last.

Great Tuner  Time owned: more than 12 months
You can find these little guys in classifieds for not much more than $30. In my opinion, they are built like a tank and are easy to use. The RF meter is worthless though.
To the SV station below, I can scan my manual if you still need one. I'm on

Oldie but goldie  Time owned: more than 12 months
I've had mine for 26 years now. Bought it brand new when I was a novice, original price was $79. It is probably best $79 I ever spent in ham radio. Lately, this only gets rolled out and used on Field Day.

I think the max power rating for this little guy is 300w. Should be plenty for a 100w rig. I've never run more than 100w through mine, and it has performed flawlessly.

If you can buy one in good shape, grab it. You won't be sorry.

good for the price, very good construction quality.  Time owned: 0 to 3 months
I gave $50 including the shiping/handling from USA to my home, so the rating should be higher, only 1 antenna out, can't be better, very small! readings on it:no need for an additional bridge, I wrote this review to ask for a copy of the manual as I don't find it in the web, I think that I will come back with a better rating! It is not a MFJ, it looks much better. Please contact me for the manual via e-mail.
