I bought the Alpha match & " mil whip" ...total junk , absolute crap , overpriced garbage...will NEVER buy from Alpha again .

I have 06 same noise . Replaced hydraulic tensioner twice , adjusted valves 3 times . Still there .

I know this video is 8 years old, but I really appreciate your video. I've always wondered about the construction of my chameleon antennas and how they rate compared to others. I just was never able to afford to sacrifice my operating antenna.

I wish I had seen this a week ago.

Honestly. Yeah, the Alpha seems like its "Mil-Spec". Lol. (Mil-Spec = Built by lowest bidder) ... Yes, i know that's not true for all military items, and there are some good Military Specifications, but thought it would be a funny line. But the Chameleon design seems to be better.

Power steering Pump thats what mine is!

Does anyone know what type torrid material the hybrid micro uses? I know the Ecom II uses type 31.

Do you still have your ridgeline? Is it still running ?

Chameleon make a first grade product that is worth the price. Top service as well

Question, is the black body of the Hybrid Micro plastic or metal? I would think stray capacitance would be picked up from the body if it was a metal body. Every unun I have looked at is always in a plastic box. This got me thinking when I saw your very good video on the comparison. I would be very interested in your comments as I am constructing my unun .cheers vk2jcc

So, You're Ok with hijacking some else's hard work and willing to give away all his process of work because you were to Lazy to Figure out how to build it yourself? You appear more of a Slime bag who couldn't figure out anything out for himself. In this case I hope you get sued , you're not anyone that I'd like to see in our hobby. Kind of reminds me of a dirt bag China trick. Why Don't You STUDY and understand the Theory of Antenna's and Signaling and come up with your own Antenna rather than STEAL somebody else's knowledge. Such a DIRTY PLAY. You Don't Deserve a Ticket!. At Least I'm willing to Pay for the Knowledge I Don't Have!

Pretty much all of these year range J35 engines do this eventually, and from my experience they will run forever with it. Both Pilot engines I've had have done it upon cold start and the noise is largely gone when warmed up.

The first HF antenna I got was a AlphaAntenna Promaster 1080 and it uses the exact same unun found in the Comet CHA250b... The only different part of the antenna is how the wire antenna is added with a counterpoise, they claim it act similarly like a off centered dipole... the core base of the antenna regardless is the unun which is exactly the same as the commercial antennas... I think many antennas are based on that copied system... I think the only other vertical with a matching unit that uses a different matching is the Diamond BB7V, there is a bank of resistors with a tiny core transformer, way different than the CHA250b. Still they are lossy matching units that render the antenna not performing really well. Again, those unun in your video are copyed from the Comet CHA25b design.

Still running ok with the noise?

Thumbs down on the review. Several of the arguments you made against the Alpha product applies to the Micro too.

I'm going to come off as mean here. This just feels like more of a "hit piece" than an unbiased review. It was really subjective.

These antennas are clearly for people who don't know any better....

I have the same knock, did anyone figure out what the problem is

This is their new version - not better than the old one: ruclips.net/video/QYewdpPH0PU/видео.html

Just ordered a chameleon emcomm iii this past week. Going to be my HF antenna for the SDRplay RSP1A. Use a discone for the sdr local frequencies

Steinhest can you measure the dimensions of the binocular core of the mpas please?

Just curious if changing both timing belt tensioners fixed the noise. Had the same knock in my 2007 for couple years now but last week my timing belt broke (supposedly Honda OEM part but came from China so...) and I've got to decide if I want to put the $$ for the repair or lay her to rest.

WoW that alpha match is like some thing i made on my spare time to just get some thig up till i had some thing nicer... Tarable...

Any notion that the US government would buy this is false. As a retired Quality manager from the Mil-Aero sector, I can say with certainty that this product wouldn't be purchase by the US government.

did you eventually find a cause?

They are both trash whips using loss as a tuning option, just make a 26 mix 4:1 current balun and slap it inside a pvc pipe and some 3/8-24 hardware and you will be at the same level for $20

As a new ham, I am constantly learning from others like you, Gil - The Radioprepper, and Julian of OH8STN. This review has me sold on Chameleon. Thx & 73!

A $300 antenna worth $50 max!!!

If anyone is interested there is an article that describes how such antennas work: www.g8jnj.net/cometcha250b.htm

Thanks, I know it's been a while since the video was posted, but nice job. The, is it Alpha antenna transformer assembly, can at least be salvaged as parts but the Chameleon is quite nice.

Wow thanks for sharing, very timely as I am on the verge of deciding if whether Alpha or Chameleon. However for 2018 Alpha has changed some of the product line do you think they have improved?

That's disgusting! I mean seriously people lay out good money for a product they expect to be built properly and what alpha put out was pure rubbish, the type of thing anyone could build for a few bucks in a few hours of messing around and still do a better job. Im not saying the parts they chose are bad (well maybe the wire could have been better) but its the construction that is just nasty. I see alpha has upgraded the look of the balun/unun what ever it is and I hope they took note and steped up their QC.

Mostly because of your video, I bought a Chameleon CHA MIL unit. It works great! Finally, (the way I have it mounted on my apartment balcony railing), I can get on every band a General Can and simply use the auto tuner in my HF transceiver! KD8EFQ/73! The alpha antenna sucks.

How is this working out for you? DId you replace the control electornics?

(multiband solution without coupler? 80 to 10 and holding 600watts) perde tempo com essas antenas..não saem nada.todo mundo sabe. MArtin ja mostrou as perdas..mas parabéns por abrir essa comercial e mostrar ;ja viu minha solução multibanda sem acoplador? 80 a 10 e aguentando 600watts? que tal? ruclips.net/video/DQ1fcRnlmVg/видео.html

Do a teardown of the new alpha military 2.0 please

Ok, that makes sense! Now I know why Videos By Mike disables his comments! I would say that when somebody who raves about a shit antenna and then leaves no way for people to express an opinion (like you are doing here) is equally dishonest! Thank you for a real and honest review, sir !

I'd love to see the inside of the new stainless steel Alpha Match to see if they improved the inside as much as the outside. If the old plastic antennas we're 1/3 the price, it wouldn't be as bad.

Those antennas are trash. It's better a 25 feet wire antenna with 9:1 unun for qrp. I tried those antennas types, for me those antennas don't work. I once used a mfj 1820 t for my surprise was better than an alpha antenna.

Many thanks for sacrificing your antennas to reveal hidden construction!!! 73, bill

I've noticed the same deficiencies with Alpha's products. Built "on the cheap" but priced like mil-spec.

I'm only a casual SW listener, but thinking of ordering the Alpha which is on sale right now. I'll go with Chameleon.

any updates? I got similar noise on 06 honda pilot

thank you for your efforts, you helped me make a decision. 73, david kk4zuu

can you sent me a schematic off the wiring on the "military" ?

This just happened to me. I have a 2006 Honda Ridgeline with 149,000 miles. It ended up being the hydraulic tensioner. There's two of them one hydraulic one not you might as well get both of them changed out.

I wanted to get on the air as quick as i could (even though I intend to make my own antenna's and experiement a bunch next year) and have been really happy so far with my Chameleon EMCOMM II I picked up based on it not needing a tuner and being able to mount it just outside the window of my "shack" (spare bedroom). I have plenty of room for big antennas but probably still wouldn't have one up yet (I bought everything over thanksgiving holiday) so again, I'm glad I got the EMCOMM. Once I install a better antenna setup I'll packup the EMCOMM and use it for portable stuff since it's quite small and would make a great portable setup.

both the transformers are 5:1 types used in the Comet CHB250.. do a search on google for chb250 clone and you'll find how to make them... can be quite lossy.. but work - sort of....... some have said its like a dummy load with s bit of wire hanging off it for the comet... cost me NZ$30 in parts to make transformer in PCV pipe, used for a few years as a wspr antenna....

Thank you very much for this excellent video : )

Great video looked and made such a transformer. Thanks for the video. R9FF 73!
