I bet the AM boys back in the early days said that SSB will never work, come on fellows, a lot of  this stuff is theory, and we learn new things in the world of electronics every day, (Keep your minds open) I can tell you that from my experience that the tuners do work and if you put them up as instructed they work very well.  The B&W wide band dipoles get a similiar slamming from a lot of so called antenna experts. A lot of them are called dummy loads as well. They  work pretty well and I have owned several of those. We tend to think that there are only a few really good antenna designs, but the handbook is filled with many types that hams never even explore. Lets face it it when it comes to wire antennas all you  mostly hear is  G5RV, Dipole and Zeps, Tuners are another aspect and opinions range all over the place on what types are the best. Some say no tuner is best, and that we have got too focused on that and should stay with matched antennas only. Who Knows?? I say if a manufactor will stnd behind his product and give you your money back if not happy, then I would doubt very seriously that any kind of scam is in place.  Give these guys a break,  World Radio used the tuner during a Field Day and I have the copy of it around here in the shack some where and from their review the tuner did just fine, They made a lot of contacts on all bands with ease. I would doubt that any true dummy load would do that. My experience was with a ham  I was visiting in Alaska and he  had one up in a tree and worked all over the place with it, Try the darn thing and then voice your opinion, it would be much better for all.

N0XE,

The biggest problem with any of this is sales or marketing people aren't quite straight with consumers. It is NOT that someone just absolutely won't make contacts with a very poor systems, but that they are misled into not quite understanding what they are getting.

Maxxcom states it is a solid state tuner, and implies something solid state is "tuning" or "switching" when it is really just an impedance swamping device (a resistor). BW implies their antenna has high or reasonable efficiency, when it does not. The same thing occurs with a Sommer Vertical that uses a dummy load to reduce SWR.

With all of these antennas, you will find frequencies where efficiency is extremely low. Efficiencies of a few percent are common. On other "sweet spots", they are not so bad. They can have 50% or higher efficiency.

As most people know, even less than 2% efficiency antennas will make contacts. I've worked Europe and Australia on 160 meters from my mobile, with about 1/2% efficiency. Of course other people using similar power would be 20dB louder than I was with a decent antenna, but I still made the contact.

The problem I have with any of this isn't selling people resistor loaded antennas. The problem is not letting consumers make decisions based on accurate upfront information,or misleading them into thinking something is going on that really isn't going on.

Of course people can make contacts even with 20dB of attenuation caused by losses that are intentionally added to systems. Some people may be happy as a Lark despite that, because the SWR meter reads low. They might not notice the S meter reads low also because they have nothing to compare it to.

But somewhere there is a blur between being upfront about HOW WELL and HOW the system works, and intentionally misleading people.

I'm not going to pretend to know where that line is. Many people are happy with resort vacations they paid too much for, and the salesmen through careful word games mostly avoid jail. That doesn't mean I don't have a right to describe what they are really buying, and compare it to better options.

From Maxx-Com.

A long time ago we were faced with a decision. Patent the technology and risk having someone make a minor change and copy our design, or put up with people like Tom who are clearly driven crazy by the fact that this thing works so well. We are not a large company and even if our patent were grossly violated we could not afford the legal fees that larger and more powerful companies could easily absorb.

There is more going on inside these tuners than people realize. That is why they work so well and that is why they have not been copied. The device Tom describes in his moral outrage at our marketing is not the same device that we are producing. The device Tom describes would not pass muster with all of the high-end users – or the ordinary folks like you and me. It just wouldn’t work.

Maxx-Com is a unique and effective piece of equipment, ingeniously designed by an extremely bright and ethical man who I have the honor to call my friend. It’s economical, almost indestructible, and it works. What more can we say?

1.) We could patent this, but then someone would copy it. So we have to keep it secret how we switch and tune networks without using devices that switch or tune.

2.) The Military and Government has used this, so it must be good. They never waste money.

3.) Nothing else works.

4.) Anyone who says any of the above sounds fishy is jealous of us.

Got it!!!! Good points Eric. Wonder how I missed them.

Reply from Maxx-Com.

Maxx-Com makes great tuners. They are economical, tough, and they work. Some very intelligent and well-written people right here in this forum have said so. Tom, on the other hand, has never used one, but has appointed himself judge, jury, and executioner. In this great country even the uniformed have a right to a public forum, but for those of you with open minds we only ask for you to review the available information and make your own choice.

Best regards,

John /  Maxx-Com  /  www.maxx-com.com

If you're an ARRL member you can read the 1984 QST review, complete with X-Rays, in the members-only section of the ARRL web site at:

http://www.arrl.org/members-only/prodrev/pdf/pr8411.pdf

The reader can draw his or her own conclusions about the product.

I thought that the WorldRadio review linked off the Maxx-com site was kind of interesting.  They said they could work anybody they could hear.  Of course, with a dummy load across your receiver, you're not gonna hear much either...

Eric, the word is uniNformed not "uniformed". Just add another n and you've got it.

P.S. For those inquiring minds that "just have to know", a small flat blade screwdriver, exacto knife and hot air gun will soften and remove most epoxies and potting compounds without damaging the electronics encased within. I do it all the time on surface mount boards cast in potting compounds. Never damaged or lost a single component.

Well,ITS NO SCAM! They work beyond a reasonable doubt. People can look down right silly when they say things about something they have no idea about or proof of. The Tuner..the one i bought is very real. Because it is as good as it sounds and the fact that i am an ex-radio eng i posted a review on this in the reviews section of this site which explains my initial findings on the subject.
QST...theres more to their findings than meets the eye, there has to be from what i have seen and know...i wouldnt believe everything you read. They might just have a bee in their bonnet about it. How can someone claim that its smoke and mirrors when it works like they say. Maybe i passed all my exams on radio theory because i am thick...or maybe i am right.
Anyway...who cares what those who dont have one think, i am one of very few hams in the world that dont have to use a manual/auto tuner ever...because i simply dont need it.. Smiley My pride is not bigger than my curiosity and that is why.

I read the review in QST that the Max Com tuner consisted of a toroid coil, various resistors and a scrap circuit board with no electical connection to any other component all surrounded by a lot of epoxy. On the other hand,I could not find the retraction that EB74MX has stated was printed in the July 85 issue of QST. Hmmmm.

I love this thread!

I'm not sure which I like better.....the P.T. Barnum portion---"A sucker is born every minute", or the Joseph Goebbels/Adolph Hitler---"Big lie" methodology.

Perhaps its the blend that makes this so special.


(BTW, when I see a review by a QUALIFIED PROFESSIONAL perhaps I'll believe the claims...but I'm not holding my breath.)

Obviously some people dont read well. I am a qualified radio tech by trade, anyone is welcome to email me directly if you dispute it. I will even give you my phone numbers and address if you so wish to contact me regarding the unit i tested. I helped build the 1990 commonwealth games radio network aswell as the marine rescue centre here in Auckland New Zealand amongst many things during my time. I worked for Telecom NZ for many years and maintained ALL VHF/UHF repeater systems and bearers (trunking included) in the upper north island of NZ. I also maintained the National paging network and was involved in the first mobile data development for commercial use in NZ. While i do not work in this area anymore, it should be un-necessary for me to qualify my ability. Ham radio is not only about comradery and sharing but also integrity. Honesty is part of being a Ham and i trust Hams the world over, I have done for many years despite people in the commercial industry giving Hams a hard time over their hobby. It is un-necessary to have an opinion of a radio expert, all that is required is that of a Ham operator, they are qualified even if not in building gear, they know how to use it. I am not willing to pull apart this unit to view its insides. It works and i can technically guess why, but its just "hear say". All i can offer is my opinion on what this unit DOES in simple setup terminology that most people may indentify with.
The fact remains, it does what they say it does. I use it, it works. My advice is dont criticise without foundation, you will be remembered for a long time.
A person once said to me; "Whats the harm in beleiving in god, if i am wrong, the worst thing that happens is i die and thats that. If your wrong and dont believe he exists what will happen to you?" My point is not about god, its about the harm in beleiving what people say. Its not foolish to beleive in something, its only foolish to criticize it without foundation.
Buy one and simply try it instead of talking about what you think you know. They offer money back if not happy. Ring them, i have! They are linked to a well known company in Florida. There really is no need for such stirring and congecture when this is available to you. It really dissapoints me at times to read Hams disagreeing over things when the simply answer is to trust each other and share the information. In the wise words of Thumper " If you cant saying anything nice, dont say anything at all."

W8JI,

How could anyone doubt a product that is promoted using soft-core porn?

I think the idea here is to distrac you with your own hormones.  {rolling eyes}

<< In the wise words of Thumper " If you cant saying anything nice, dont say anything at all."  >>

Pure BS!

One of the purposes in this forum is to poke holes in bogus products and this fits at the top of the list.

Just because some government agency bought something is not an endorsement. Samples of products are purchased all the time. If the military thought these were hot stuff, you'd see them all over the place instead of real high power antenna couplers that are the size of suitcases.

I don't guess you have been around too many US military communications facilities.

Oh.. so the old "my daddy is better routine comes out", how mature. The fact remains that i put information in this forum for people to use for their benefit. If they dont use it, thats cool. But its funny how the last 4 QSO's i have had using the matcher are better than any other aerial combo i have...but then what would i know being a Radio Eng, i have never been in the US Military. It all makes sense now..I should join up so people take me seriously. While i am at it i can go steel some oil too!

Of course it works ...

So does a 100w light bulb and a dummy load.

There is no mention of the impedence matching range for this thing, so the only logical conclusion is what others have said - it's a 50 ohm resistor across the SO-239.

The world (especially the ham world) is full of suckers!
