Outstanding! Thank you for your time and effort.
Glad it was helpful!
Very good test! Thank you for this information.
Thank you for the comment! I'm happy to help!
Thanks for this video. I love beating those scammers !!! I now know what to look for. Thanks again and I subscribed and look forward to seeing more of your videos;
Thanks for the sub!
Спасибо тебе!
Теперь понятно, подделки тоже начали делиться на премиальные и обычные )))))
I'm happy to help!
Very good video, though I was surprised the “cheap” antenna did as well as it did. Looking at my Nagoya NA-24J antenna, it read 20W for its power output, while the fake ones I've seen say 10W. Taking SWR readings with Surecom meters can be off by wide margins since there's no way to establish a ground plane, even with steel ground plane shields (which are no longer being offered with Surecom meters due to cost and because they don't really work). Still, I would love to see you test some cheap no name antennas next to your Nagoya. Oh, and I highly recommend the Retevis RHD-771. It's a higher guage antenna that has worked out very well for me. Cheers.
Thank you for the comment! Yeah, I'm familiar with the Retevis RHD-771. It's a very good antenna.

I have that antenna straight from btexh website and it says 10watts
What's going on with frequency detection with first antenna on 2m band. Why SWR meter shows 208.105Mhz?
Excellent very clear to understand video, just checked my 2 recently purchased Nagoya antennas, yep they are fake!
Glad it helped
How did you check? the one that says "Btech" is NOT Nagoya's packaging
Just ordered the NA-771 from Amazon. I'll find out Wednesday which one I get. Thanks for posting this.
Happy to help!
So was it a legit antenna?
@@rallypoint1 The antenna from Amazon is the legitimate one, at least in my case. The link in the description.
@@rallypoint1 yes, I received the genuine article. And it works great. Any future handhelds I buy will be equipped with them.
@@ElectronicsComputers Awesome!!
Thanks, this really helped.😊
Glad it helped!
The fake one is actually not bad too according to that SWR plot. I think it will be better than rubber-duck antenna that comes with the radio.
Anyway it worth 8$ but the original one is significantly better in all its aspects.
Where can I buy an original?
Great video! When you try the cheap antenna at 144MHz (time 2:16) your SWR meter indentifies it as 208.105MHz, and SWR is 1.72. Thats a bit strange?
Thank you for the comment! That SWR meter sometimes shows wrong frequency readings but SWR value is very accurate.
Greetings. Is it safe for a mono band portable radio installed with an aftermarket dual band antenna?
Absolutely safe but dual band antenna may not perform as good as a dedicated one band antenna. You have to compare SWR values on the particular band/frequency that your radio works.
@@ElectronicsComputers thank you.
What radio output power setting are you testing with?
That radio was just out of the box with all default settings. The RF output power was set to the maximum.
Thanks for the charts
Happy to help!
mine has the off tip, not looking original with a logo, but my qr scanner took me to their website, and i got it straight feom baofeng so looks can be deceiving
That QR code can be printed on anything you want. But in general, both antennas perform pretty good. The difference is only visible on some testing equipment but in real life, you'll never notice that difference in antenna performance.
Thanks for this.
Welcome!
Do you know if NA-771A (A for airband) is available anywhere?
The links for that antenna is in the description box below the video. Nagoya NA-771A is not the best option for airband but anyway it's way better than most stock VHF/UHF antennas.
@@ElectronicsComputers what would you prefer for airband then (118 - 136 mhz)? Also didn't find A version link, only the one for stock 771(non A)
is the spacer gasket thing gonna affect the performance?
That gasket is only for dust protection and it won't work for most radios.
Not at all
Never mind fake vs real. I’ve recently completed a vswr check with the stock antennas sent out with a Baofeng and a Quansheng HT and the results were terrible. All four tested were well over 4:1. One of the rubber duckies was into double figures. Whereas my hand made slim Jim comes in at 1.1:1.
mine doesn't have qr code on base and has a plain silicone tip no manafacturer name is it a fake?
Most likely it's a fake antenna but it also perform pretty good, at least the fake ones that I've tested.
@@ElectronicsComputers it's ok I sent picture of it to Nagoya and it's genuine, I have better antennas anyways cheers
half of this youtube is total nonsense and Nagoya itself has had to issue a list of official distributors. The packaging you see as claimed "genuine this is ONE distributor putting the antenna it in their own packaging. the packaging listed as "fake" here is actually the packaging the Nagoya comes in from the factory. This is the same nonsense the Btech aka Baofengtech (which is not hte official baofeng company by one of scores of distributors) did making their own packaging for Baofengs it is selling and then claiming other packaging is "fake."
@@teo2975 Totally agree
Are the ones from the Aliexpress links in the description legit or no?!
NO! Only from Amazon.
@@ElectronicsComputers Amazon is not a Quality Guarantee..... they sell BS too
What about antennas with the blue lettering
The blue ones are the old Nagoya style antennas and they don't make them anymore.
Nice👍
Thank you for the comment!
just tore down a 773, dont know if it was fake but swr was useless. it had a tiny tight wound loading coil inside which i removed and replaced with a large 5 turn wide spaced coil around the outside of the original housing. it now gets 144-146 below 2.0swr with one or 2 sections collapsed. fully out it tunes 137 so ok for sat rx. 70cm is non existent. to be fair, the antenna that came with my vx7r is crap in any configuration. the best rubber antenna i had was on ic-t2h . i have yet to find a handheld multiband that works well
There's so much fakes nowadays so you have to be super lucky to find the original one.
You tested the antenna lying down horizontal this will give poor results. Also these antenna's use your body as part of the grounding. So I dont think the results are accurate. K
It doesn't matter, because both antennas were tested at the same conditions and both SWR meter and antenna analyzer show pretty similar results. I agree that it's not a scientific or super accurate test but the point was to compare those two antennas and find out if they perform differently. And this test clearly shows the difference in their performance.
Such great antennas, but you gotta pay full price. $20 isn't that bad for an antenna that kicks so much ass. Don't be cheap. Get the real thing!
Totally agree!
I pay 3 dollar then fine tune at home. End of the day it's just a bit of wire
I buy from 'B-Tech' and so far...No “cheap” ones. I did buy 3 “cheap” ones (Ebay & Cheap Price = "Cheap Antenna")....only one had bad SWR readings...BUT some of the “cheap” ones do have pretty good SWR readings.
So far..The only way to tell the “cheap” ones by looking at it, the real ones, if you look at the tip.....the little Tip should say "NAGOYA"..if it don't, “cheap”.
Damn. I got ripped off again. I'm yet been able to get a genuine one!
The link for the original one from Amazon in the description.
Great job
Thanks!
Судя по сайту производителя, обе антенны являются оригинальными...
You cannot do a meaningfull SWR TEST USING small meter and handheld radio as the antenna under test is really half of a diople, the other half consisting of your meter, radio, and your body holfong thr radio. As you show, with the radio laynig an the bench, SWR will be affected by any metalwork supporting the bench.
Here's the corrected text:
I know that, but if you're doing the same test in the same environment and the only thing that changes is the antenna, then you can get an idea about the antenna's performance. Also, those antennas were checked on a more advanced device (you can see the results on the graphs), and the results are about the same. The main idea wasn't to determine the actual SWR but to see if the fake antenna performs the same as or worse than the original one.
1st 😍
Thanks!
Разберите их и посмотрите что внутри.
Этот китайский тестер не особо точен, все таки КСВ антенн лучше и точнее мерить NanoVna
Thanks for the tip!
Friend, I am a newbie, I bought 2PACK BaoFeng UV-16 Max V2 10W High Power IP68 Waterproof Walkie Talkie Support Type-C Charger Long Range Radio Upgrade UV5R PRO but I can only talk up to 500 meters, I need at least 10km. I'm doing something wrong or it's not the right model (these are given for distances up to 50 km. which I don't need) What do you recommend, thank you thank you
Is the power set to maximum, and what band did you use? You'll never get 50km or even close with those radios unless you're in space or in a straight line of sight. But something about 3-10km should work depends on your terrain.
nice
Thanks
My nagoya na-771 antenna wont even screw down on a Icom HT. 2 turns and its stuck . Aliexpress is a trange place for criminals.
Check the thread maybe it's damaged or something stuck inside.
I think both of them are genuine. You can check photo at product file.

It is seen that the logo is not available when you zoom in the pointed plastic end.
May be the new series have qr code and pointy plastic tip with logo.
In terms of quality and performs there's something clearly wrong with the antenna from AliExpress.
Exactly. The Btech packaging is Btechs (and Btech/Baofengtech is NOT the Baofeng company) own packaging, and the upper packaging claimed to be "fake" packaging in this video is actually what comes from Nagoya factory. The claim that only those antenna marked "Btech" or "Baofengtech" are legit is the same nonsense claim that only Btech aka Baofengtech are the only legit Baofeng radios. BTech has gotten into trouble calling other US distributors/sellers UV-5rs "fake" even claiming that UV-5r was "discontinued." The actual Baofeng company had to issue statements on its website stating BTechs claim was false. Looks like they are now pulling same nonsense with nagoya antennas, and Nagoya has had to counterr Btechs claims, and Nagoya has noted Btech is NOT the only authorized US nagoya seller. Reminds me of the Btech claim that brown Baofeng box meant it was "fake" when Baofeng factory itself puts them in brown boxes.
Bteck/Baofeng tech is one of MANY official Nagoya distributors.
Do we think the other distributors are putting the name of a competing distributor on their packaging???
@@teo2975 do they ship nagoyas from China? Cause mine I just got shipped from China, came in a green sleeve and says made in taiwain on the packaging. I havnt totally written it off yet cause maybe there made it Taiwan but then sent out to China for shipping but seems strange.
Hi. I'm going to receive a genuine Nagoya NA-701 HT SMA male Antenna, but as far as I saw in other reviews, ALL these are just CRAPWARE. It's crazy how the factories don't perform the MINIMAL NECESSARY SWR tests, and they release sticks that are somewhat resonant at 150 - 160 MHz (VHF), and 440 - 450 MHz (UHF). The ridiculous fact is the justification that the factory provideswhen you contact 'em, saying that "a counterpoise wire is needed" !!!!! Counterpoise on an HandHeld radio ?!?!? The same shit happens with DIAMOND SRH 36, SRH519, SRH 701, SRH 771... There is NOT A SINGLE AERIAL resonating at 144 or 432 MHz at all !!!. I have two old COMET SH/85 (BNC) and a SMA-3 (SMS male) PERFECTLY WORKIN' at 144 and 432 MHz !. It appears IMHO that THE ONLY DECENT antennas are the ones produced by COMET (NGC now). I will see the NA 701 that comes from Spain, as here in Italy, Diamond is easy to find genuine, but Nagoyas are ALL FAKE. Hope my two cents are helpful. I measure through a base for mobile antenna with a large metal base, and the right measurements are successful with Comet SB5, SH95 (mobile antennas), and COMET SH85, SMA3, CH701X. All these sticks are PERFECTLY centered and show 1:1 to 1:1,5 SWR at VHF and UHF HAM frequencies ! 73.
Tests were performed with: YAESU VX-2E HT Transceiver, YAESU VX-8E HT Transceiver, KENWOOD TH-78E HT Transceiver, YAESU FT-847 ALL BAND TXCVR. SWR Meters used: ZETAGI 430 Pro Line VHF/UHF SWR Meter, DIAMOND SX-400 VHF/UHF SWR Meter. Cable for the external measurements: BELDEN 9907 50 Ohm Double Shield, High Prop. Speed. / Lucent Teflon Low Loss military grade cable.
There's lots of fakes nowadays and it's really hard to find a decent antenna. Also many sellers in Europe sell stuff from Aliexpress and sometimes it's hard to say if it's a genuine product or not. This is why I prefer to order some equipment from specialized shops in the US. I hope you'll get a decent Nagoya NA-701.
@@ElectronicsComputers I got the list of European authorized resellers either from Diamond and Nagoya/Reuex, and l bought regular products. Despite this, with respect of the two companies, some products are crappy... :) 73
I have two genuine 701s. Their performance is equal to a Retevis or Wouxhen (sp) antenna.
I received the Nagoya NA-701 HT SMA male, and it's genuine. This is actually my definitive VX.8R antenna, as it's perfectly resonant at HAM center bands. I confirm after further measurements that the NA-771 SMA male is a piece of crap.
