Hello my friend, awesome video. Great job explaining set up. I realize Chameleon antennas can be a bit expensive, however the quality of the designs is amazing. Thank you!
Mega video and cool project. Unfortunately, I'm quite sensitive to beeping noises, which is really bad in your video. Best regards and thanks anyway
Looks like a very solid portable antenna. They did a great job designing all the accessories. Afraid to look at the price, but buy once cry once. Been eyeing the JP12 since it is an affordable option.
$200 USD vs. $600 USD is an excellent great alternative.
Exactly - you get what you pay for. The CHA PRV is also build on the LEGO system which mean that just about everything else we’ve on our website + all the new accessories will be compatible with it.
Excellent demonstration/video...also thanks for the fully fluent English.
Chameleo needs to come down on the prices. It cost to much for low income consumers. 73 AE4OY WILLIAM A. PEACOCK, Sr. Blackshear, Georgia USA 🇺🇸
Please, it’s always this way. Make your own! There are directions on the internet….
I’ve no real answers for you. If the manufacturing cost and the quality wasn’t so high - then the final cost would be cheaper.
Great video Paul. I bought the CHA MCC over Christmas. It’s an awesome portable antenna to take along with my IC-705. Bill, KC2KNA
Excellent video Paul !
Thank's Paul for this video and description of this portable antenna. I have an JP12 for portable activity. Best 73,s from Bruno F4LBD
Hello very nice antenna , but Chameleon are much to much expensive!!! 73 qro HB9GUR
As with everything, these aren't designed for everyone to buy. It has a use case and those who need this device will buy it.
"Antenna is the most important, followed by coax, then lastly your transceiver".

Perhaps phillipe you meant to say “but Chameleon are too much expensive for me” ?
@@cwqrpportable not at all I have a few of them at home, but I still find them to expensive. For exemple their tripod is exactla the same on Aliexpress for more than half the price...
@@cwqrpportable no he ment in general and he is right..
@@dennis8019 I’ve bought lots of chameleon products but find this one crazy
Very similar to the MP1.
Thanks for this demonstration Paul. 73,s
Love this antenna and Chameleon products though I prefer the MPAS 2.0. The PRV is lighter and more portable, great for air travel to the US Mainland when we visit our son in college.
This looks like a good-quality antenna. It has some similarities to the Super antenna MP1. I use the Super antenna MP1 Max. I wouldn't trade it for this antenna. Thank you for a well-presented informative video Paul.

Pekná recenzia. Anténa dobre prevedená, mechanizmus ladenia zaujímavý, na aktiváciu v rámci POTA parku OK, s desiatkami W to bude fungovať dobre aj na 40m v SSB. Pri piknikovom vysielaní nebude vadiť čas zloženia ani rozmery výmenou za nenápadnosť. Na stránke výrobcu sa uvádza aj SOTA, čo vo mne vyvolalo úsmev, niesť v batohu a skladať toto niekde na "ťažšom" kopci sa mi nezdá rozumné :) Cena 853€ za kit + 176€ za trojnožku + doprava z WIMO je na naše pomery šialená :) . Ak by som riešil setup pre mestskú POTA, siahol by som po C-WHIP za 30€ / pásmo (ktoré mám pre WWFF z auta), svorka na stôl v najbližšom hobby markete za 5€, U Awas-a držiak na zrkadlo za 10€ + držiak mobilnej antény pre 3/8" za 8€ ;) "Linkovaná" protiváha s konektormi sa dá spraviť za 15€. Navíjač na protiváhu vytlačiteľný na 3D alebo zo sotabeams za pár €. Nevýhoda takéhoto setupu je dĺžka 1,5m a váha, čo ale pri mestskej POTA nebude vadiť ;) Pri SOTA alebo "odľahlejšej" WWFF je asi vhodnejšie niečo ako EFHW. Alebo pozrieť u Aliho, portable vertikál s laditeľnou cievkou v pate vrátane tašky a dopravy tam je za cca 150€ (PAC dva-násť), kvalita bude samozrejme horšia. Možno námet na ďalšie video? ;) Tono, OM1AEG
Pekná anténka.
Veľmi dobre dielensky spracovaná. Klobúk dole.
Keď ju niekedy budeš pitvať tak si niečo také vyrobím. Lebo 500 € je dosť. Aj keď táto oprávnene.
Tie tvoje videá neustále zlepšuješ takže sa na to dobré pozerá.
Vlado OM0AVV.
Thanks for the good video!
It's interesting matches system with driving coils.
But, expensive to buy it and not so easy.
It's useful thing if you don't want to make similar by hands.

There are enogh much cheaper (and good quality) alternatives. TNX for the nice video.
Hi Pavol
Ray M0RAY here. I like the look and concept of this new antenna. However I wondering if it will be any cheaper to people in the USA 🇺🇸. I am currently in Houston, Texas, for a very short visit for my lady friends birthday on Monday 11th of March. I'm hoping to be able to set up or keep a radio here eventually. I also have a very similar antenna to this 1 in this video. My antenna for portable use is called the "SUPER ANTENNA SYSTEM ", also from the USA 🇺🇸. The basic SUPER ANTENNA has all the very similar components that you demonstrated here, but I have not yet used my one.
From a video that I saw many years ago, the results were excellent.
Kind regards to you, Pavol,
De Ray,, M0RAY, or if I had a radio with me over here, W5/M0RAY, lol.
73, de Ray.
Hi Paul, thanks for the video. I use this antenna few months and it is a very nice portable antenna always in my backpack. A little comment, you can finetune the antenna also with the number and the lenght of the counterpoise wires. It is described in the manual. I love it! (OM5HAM)
Be interesting to see how it works with the 17 foot telescopic whip.
With the SS17 it works PHENOMENAL!
Looks like a Wolf River Coil with a plastic sleeve over it.
😀
Instead of disconnecting two counterpoises, try folding back all four. E.g.: You were fine on 40m, therefore shorten them/fold them to half length for 20m or 1/4 length for 10m respectively. That should gove you better SWR & slightly better performance.
Great! Thanks for your hint! 😉👍
NICE Presentation and very nice product, how ever out of reach for a lot of people because of price....us average people will have to get creative and make some like this our selves. for a coil use a piece of 2.5 inch dia. or so air dux about 10 inches long and one of those 17.5 foot or so masts and a few more odds and odds and ends and you will have a poor mans portable antenna.
Hi Paul. Many thanx for this video. Could you say me is this antena could work on 11M without a tuner? Have a nice day. Damien
Yes!
Hello radio friend,
what inductance does this coil have, have you ever measured it?
73, Ingo
Could I mark on coil where is the best SWR for every band ?
Yes - use a metal marker.
£530 wow that's a steep price for me. The antenna it's looks very well made and looks very nice.
Would love something like this but a little rich for me unfortunately 😭
73
With the 17' whip will it reach 80m band?
No - you’ll need a 80M loading coil.
I thought the definition of QRP is 5W or less.
not for ssb, 5w is for cw. 73 qro HB9GUR
When work in home on analogy antenna, but construction on China components 😅 73 de R2BBX!
That’s a handsome price….
Yes it is when you understand quality and performance. When people are going to understand that isn’t NOT made in China but in the USA with the BEST possible materials - people will appreciate the final results. You’ve to look at the details.
Hi Paul, could You tell me the coil's wire AWG reference? Thank You so much. 73 PU2AOO
Probably more then ample for the power it's rated for. Looks to be 14-16AWG from just eye-balling it.

Na ja wer es braucht soll sich den Kram kaufen aber ich kaufe da lieber einen transceiver für und baue weiterhin meine Antennen selber aber 55 und 73 und noch schöne QSO
in the noise but he is 5/9
Many tuning errors in video. Also errors on the counterpoise system.
looking great but 600 plus dollars?? u have to be kidding ...
Find me a similar product - similar manufacturing quality made in the USA - similar package deal with similar parts cheaper online?
Quality product, but priced way too high.
Find me the exact same thing online cheaper?
Nice quality but the price ? Thats a lot of ham sticks😊
The price is directly competitive with similar products with “similar” or lower quality!
My goodness it’s expensive. Is it worth it?
Or you take a 20 meter old speaker wire you found at the neighbours garbage and a cheap Matchbox....(if you do not have a build in tuner)
How do you support your 20M speaker wire in a deserted area like Dubai, Arizona or on the beach?
Or how do you setup your 20M wire on a balcony at the 2nd or 5th floors?
Or do you install your 20M wire in a commercial parking lot lots with 100’s of cars?
Or do you set it up at the top of a hill?
Well, this is almost complete set of things I don't like on ham radio antenna designs. In fact, it's much more like set of things you can use to build something that mimic antenna and, if you are lucky enough, then, in some particular cases, you put that mixture of things together in the way, it somehow radiates into some usable direction. But it's much more like casting a chaos magic spell than building/installing an antenna.
First things first. Antennas are made to radiate, not to obtain low SWR. In fact, if you put enough power into that thing, you will see where the most of the power burns in a heat. Every antenna does this, the goal of antenna design is to radiate more and burn less, which leads to some compromises. Achieving low SWR is important, if you cannot feed the antenna, then it is completely unusable, but it's the only small part of the whole design. When it comes to well designed antenna, then SWR potentially can be used to fine tune the antenna in the installation process, but it is the property of design whether is this possible or not. And this is definitely not possible in this particular case, at least because it's not fine designed thing, it's much more bricolage with almost unpredictable outcome.
In this case we have vertical radiator with some radials, which leads me to the conclusion, it somehow utilizes ground plane mirroring. That tiny radials are not able to create solid ground plane on such a low frequencies, so it's much likely they are somehow coupled to the earth, which implies that leveling the base of that antenna above the ground is a kind of unfortunate, because it also levels the return path of the current above the earth potential, which requires RF transformer to feed that kind of antenna from some typical transceiver. That thing made of ferrite toroidal cores does not form proper RF transformer, so, in my opinion, it is much better not to level the base of that antenna above ground. And you can also put that two rods to the opposite side to make the radiator little bit longer, which, in fact, introduces similar outcome to leveling the base of the antenna, but without messing with the feeding system.
The design itself is probably based on ideal λ/4 vertical utilizing serial reactance to make the real relatively short rod electrically a little bit longer. The problem is that the coil itself is real component, not an ideal one, which introduces some limits into that kind of design, that are in this particular case heavily exceeded, especially when it comes to lower bands. In my opinion, random rod (or wire) feed against ground tuned by L matching network would give you much better results, but well, ok.
Mechanical parts. The first thing is that spike. The only way how to use this is to hammer it into the ground, but it has no protection against the hammer. It needs some plug to put into the spike, then hammer that plug, not the spike body itself, then remove the plug. This is the easiest way how to design this and you can use almost anything to hammer that spike into the ground, e.g. nearby stone.
The second thing is that coil. It is covered by silver coating, which is ok, but it requires silver coating on that counterside wiper (or what) to make perfect contact. Copper touching silver coated copper is really bad idea for both mechanical and electrical reasons.
The third - that metric (not imperial) banana thing. It's so easy to accidentally unplug it. Using thumb screw together with U shaped contact would result in much rigid connection. This would open the possibility to add some elastic band to the end of the radial, which would introduce some tension making it straight. And why the hell are that radials dark green, which makes them almost invisible in a grass. It's easy to trip over that thing if you don't see it. Yellow would be much better.
Nice looking antenna until 239 connector. Two extra screws surely not that more expensive but then again, still using these out-dated connectors rather than N-type.
Holy crap, your tower in the background is leaning a lot. Hard to see in video but thats not how to guy towers.
he’s got the lot on a shallow slope, not the tower leaning. Tower is straight
@@IZ0MTW Maybe look a little closer and use ALL the surrounding buildings as reference. Tower has a big lean or ALL the buildings are leaning....
Please check this video first: ua-cam.com/video/xrZfV3ud7Kk/v-deo.htmlsi=kGfVx6nGPrNlPjKi
@@bentheguru4986 actually I watched carefully and you’re right. I remember watching the video of the tower installation, that’s why I couldn’t believe what you said.
I think he could adjust at the base with the nuts though.
It's optical illusion called Spherical aberration.
I'll agree that it looks nice but I believe that the maker is in it for BIG bucks. This thing is way over priced. I will not be buying one but rather most likely making one myself at a small fraction of the cost.
I bet verry overpriced take the base plate off and paint it black its a mp1 copy lol
can I get one in Europe ????
Yes from WIMO or Martin Lynch.
