- I was asked to do this video using the 4 antennas on the Baofeng.The antennas used were;
1) The stock antenna
2) The Nagoya NA771 antenna
3) The Diamond RH770 antenna
4) The Diamond SRH805s bullet antenna.
Using the Chesterfield repeater GB3EE on UHF for the reference signal which is around 20miles from me and brings in quite a bit of static at the best of times,it seemed a fair test for the antennas.
Rest in peace ear phone users
Hey guys, The small SRH805S antenna is a Chinese copy. It is not a real Diamond Antenna. We are in the process of stopping them from using our trademark name.
good news!
I'm commenting years later, I know. The NA-771 ( Nagoya ) in this video is fake / counterfeit, and as stated by Diamond, the SRH805S in this video is fake / counterfeit also.
@@xxM5xx Nagoya did have REAL ones printed in blue. The fake blue ones will rub off easily. The real blue ones are printed and coated.
It is not the blue ink issue alone. Look at the shape of the base.
@@xxM5xx yes, but the fact is, Nagoya made early units printed in blue.
Glad you did that little test for us... I was thinking of getting the Nagoya and now you have made up my mind...cheers
Just linked you up on my blog, nice test. Waiting on a 773 to arrive today and I'm hoping to sit my foundation in around 2 months!
Yeah I just ordered a couple, hopefully they are legit, and I especially hope they improve my transmissions.
Nice video, and great practical application antenna test.
Cheers Jester,you wont be disappointed with the performance of this antenna! Great vids BTW,keep em coming ;-)
Thanks for the appreciation.You`re right,in tests the NA771 came out better than any of the others.Good to know other radios benefit from this antenna as well.Cheers 73 M6ZEF
That's for the test. Been looking to improve upon the stock antenna. Ordering a Nagoya 771 today.
Cheers for the comment,it really is a well performing antenna.best wishes.
Thanks mate.Good luck with the antenna and also with the foundation test! i just passed mine recently.cheers M6ZEF
Hi Richard,thanks for the message.I have found the the Nagoya NA771 works the best on vhf/uhf and is reasonably cheap.You definately get further than the stock antenna.But for real improvement the `Harvest` RH770 is great,but it comes at a price.Hope this helps.Thanks!!
yeah,definately.The Rh770 brings in a load of static,although the receive is the same as the NA771,but i read that being telescopic can affect the swr aswell.The NA771 just seems to work better for me??
Thanks for the comment.You will be impressed with the Nagoya im sure!
Ajudou muito. Obrigado, excelente !!
Good video, and greetings from Mansfield.
Thanks for the great comparison. Quick question, did the little diamond stubby fit flush on the baofeng? Been thinking about getting one to use while out camping for LOS chatting
Great comparison video. To all of you thinking how to improve your hand held, just buy the Nagoya NA771, Just buy it !!!
Great antenna that works the best on not just the Baofeng but also the Quansheng TG UV2. I have both those radios by the way. 73's
Nagoya NA771 is the best antenna?
Although i must admit i have never transmitted using the Rh770 as im not licenced yet,but im taking my foundation exam this week so i could give it and the other antennas a proper test in the field! ;-)
I'm getting a pair of these radios Baofeng uv5r will be using them while camping and will have attached to the back on my tactical vest with molle connectors so i wanted to know if theres a good antenna maybe one of those that you have that would be flexible enough so my walking or what ever wont break it? rubber ducky antenna style.
Muito bom. Nagoya 771 the best
Have you checked the SWR on 144 and 430 mhz?
UV-B5 doesn't seem to have the cutouts when you move the unit around.
i have it one..same model,may i ask u? if we want to get clear voice when speak through UV-5r..what most important we need to do..(distance more 20km)
VALIOSA INFORMACION, MUCHAS GRACIAS, SALUDOS DESDE VENEZUELA.
Thanks for the video. ?Can you recommend what you think is the best antenna for the ratio you're using in this video the uv5r, thinking of getting one. Thanks : ) Tyler
hi Tyler,thanks for your comment,in my opinion the Diamond RH-771 would be the one to go for! cheers!!!
Thanks Man, much Appreciated : )
i have a one week old uv5r plus with the nagoya 771 and im very impressed . i was hitting repeters over 100 miles away on 2 meters from my local hump..its not really a hill..70cm was very good aswell..well worth the 6quid free shipping from the uk :)
I'm gonna assume ^ added an extra zero on accident 9 years ago
Cant tell if this is better then the factory antenna I am hoping it is it's alot smaller
Thanks for the usefull explanatory.

Nothing about transmission and SWR?
I tested a so-called Nagoya 701 and the SWR was so high I threw it away. The helical antenna that came with it was slightly less than 2 and was the best bet for available portable antennas. Best result was with a whip antenna cut to size on a magmount stuck to a biscuit tin lid which gave SWR of 1.1
for US/Canada GMRS and MURS users get
23cm 0ft. 9 - 1/8in
VHF 154 1/8 3dbi
UHF 462 3/8 2dbi
NAGOYA NA-666 DUAL BAND 144/430Mhz
on testting my diamond RH770 I found that the standard antenna that came with the radio performed better, i took the rh770 to an event station with my ameture club and the location was on a hill with nothing for around half mile in any direction , the rh 770 got about 3 miles and the standard antenna that came with the radio got 7to8 miles on the same freq in exactly the same spot. done some further test with the little stocky super high gain one you can buy off ebay its apros 3to4 inches long with gold band around bottom where it connects to the radio, this performed better than the standard one and i got aprox ten miles on it. obviously day to day the propogation would changed all test done by myself and fellow ameture operator caried out within 5 mins to narrow down propogation change. good little radios and the standard antennas quite good id rate the standard 6 out of 10, the high gain stubby 7 to 8 out of ten and the diamond 770 3 out of ten.
Have you tried the U-V Baofeng antenna? Seems to work better that the stock antenna that comes with the UV-5R plus.
Havent heard of that antenna,but will have a look for it on ebay and if its reasonable ill go ahead and get one.thanks!!
got the night guard on the radio haha mick bless
It is because i have hot spots where the signal is stronger in different locations around my house.I`m not high up either,so i can only receive weak signals ;-)
So all these antennas only produce static for the most part.
That Nagoya antenna is a counterfit. I know this because the nagoya logo is in blue, and real nagoya antennas are in Silver. Check amazon for the counterfit details.
This is true. For me the dead give away that the NA-771 shown in this video is fake, is the shape of the molded base housing. Nagoya has a good web page online exposing the fakes.
I've seen a lot of these fakes and I have seen many genuine NA-771. I own several of each (genuine and fake). There is a huge difference between the fake and the genuine Nagoya NA-771 in behavior / performance. The fake NA-771 can damage your radio's transmitter stage (or automatically fold back power to protect itself), particularly at the highest power settings. If this happens you will think the NA-771 is a bad design when in fact you could have a counterfeit (clunker).
Diamond commented that the SRH805S in this video is a counterfeit too. I have a fake SRH805S and it is terrible. The counterfeit is terrible , confirmed. I threw it away. I wish I had a real genuine Diamond SRH805 for comparison. Using a HT and distant repeaters to test antennas isn't the way to go. Spend some money on actual test equipment (or borrow a friend's) if you want to test various antenna to be sure an antenna is good and won't damage your transmitter.
Not true. Nagoya did in fact, originally had blue lettering and molded base. I have an old NA-773 with Blue lettering. It's about 7 years old. SWR is 1:6:1. It works fantastic. Only a few years ago, did Nagoya print in silver.
SHAPE of base
I had to mute the video because of the dang ticking clock, I HATE ticking clock. So what is the best antenna?
Thanks
Cheers sir
Do you know any websites where i can find repeaters in the UK?
repeaterbook.com
I have the 771 for my BFF8+ and think you could be close to my QTH.
hi sir how do you change the languige on the radio a chineese lady keeps talking to me everytime i change modes
hi David.you have to go into menu then scroll through until VOICE appears,hit menu to highlight,then change using up and down keys from OFF,CHINESE,ENGLISH then hit menu then exit.job done! ;-)
Hmm...that's weird, you should get the best results with RH-770, it's the longest radiator. Of course the resonance is totally different on 771 than on 770, you might accidentally hit the black spot for 770. Are you sure that NA-771 works better?
Speaking of counterfeit antennae...at least some of the new BaoFeng radio models now come with a new "V85" antenna that is supposed to be an improvement over the prior antenna.
Does anyone know how to verify that:
1) it is an "V85" antenna?
2) it is a genuing "V85" as opposed to a counterfeit?
There are no markings indicating it's a "V85" anything. However, it has:
a) "U-V Antenna" and "BAOFENG" embossed/moulded into the thicker base section of the antenna sleeving (but the "-" I'm using here is actually a half-high 'dot'), and
b) inside the connector on the outer ring it has printed "FM/136-174/400-520MHz" (white text on black background).
Those are all the identifying marks available.
my uv5r 8w came with one of those, and honestly, it aint half bad. idk what v85 means, but its better than the stock one in this vid.
seems the second antenna was the best ,,how much was it mate cheers shane
Hi mate the Nagoya NA771 on eBay are around £6 or you could go for a Diamond RH771 same whip antenna.cheap enough mate!
ordered one thanks for the reply fez
PMR will only get a few miles or so,so unless you`re local to me it wont really work long distance.
It can. I've had 30 or more.
A good antenna is the AL-800 HighGain Dual Band Extendable Antenna SMA-Female it cost from £12 to £15 pounds but it works i have try them all by far this is the best...
thanks for that ,I'll have to have a look for one!!
Take a look at it

Bless Up :)
You are hitting a 20 mile repeater with the nagoya?? I live in Mexico City and Im not able to hit a 3,2 mile repeater with the same setup!!! There most be something wrong with my configuration.
geography matters alot, expecially for the UHF, i can access a 2m rep 70 km away from my home since the rep is in top of a hill... and with my directional antenna i can access rep 124km away with just 1watt
my dad has this radio nice radio
thanks for the comment vina and for subscribing!
:) welcome
please share your video on my page
Yeah,Michael lives in Chesterfield where this repeater is located.Unfortunately i cant hit it from my QTH,but have heard him quite a bit.Cheers and 73 from M6ZEF

SQUELCH! SQUELCH DAMNIT!
Holy shit that was a bit loud eh?
Turn the freaking thing down, it has a squelch and a volume control....
you can damage the walkie by not turning it off when antenna is not on.
Only if you transmit.
How do i use it to listen on tetra? Is it the dsc and such i need right? I bought one fre counter that is on its way that tells about these signals also. Tells the dcs and tdcs or what it was called. But is that all that need to be found and put into the programing and then be able to listen? I have seen people using some called chirp. Im still new. Havent hadd that much time to figure it out.? Oh and thanks for info. Releveaving;-) I have had it of but havent touched the PTT. :-)) Thanks.
All your antennas are counterfeit. Sorry bro
Fake ot not it worked perfectly.
Isn't that a fake Nagoya? Seen a couple videos showing what's shown here is a fake. Bet the real one is even better! Link for one of the videos I've seen recently th-cam.com/video/sJEMYdR172w/w-d-xo.html
Edit for wrong link
10+ years late but for anyone watching - that Nagoya 771 is a fake. You can tell by the blue writing on it. If you ever plan on transmitting then please buy a real one. You don't know what the SWR is or if it will kill your radio unless you have proper testing equipment.
Your Nagoya was a fake. A real Nagoya should have silver printing, not blue.
I think your find the Diamond antenna is (2meters 144Mhz) (70cm 430Mhz) and (23cm 1200Mhz) antenna, i own one, if your a real ham radio operator then you would know that. You said its a 6meter, 2meter, and 70cm antenna. You do realise that 6meters is in the 50Mhz range??Ive been a licenced ham radio operator now for 15 years and i use all the bands HF/VHF/UHF.
