Thank you so much for testing this!!!!

It worked out great! You upload the most informative videos and you are a damb good host!

I really like your videos and antenna designs. Enjoying the channel!

Definitely a great review and confirms aspects of my experience with using the product. My experience using the EDUP v Sunhans amplifiers on a DJI Phantom 3 Standard is that the lower power Sunhans amplifiers provide a stronger cleaner signal and thus a much longer reach. Using panel antennas and Sunhans 2.5w 2.4ghz and 2w 5.8ghz, I have both signals out to a distance of 7km (absolute limit of battery endurance) whereas with the EDUP 4w and 5w respectively, I start to lose control signal (5.8ghz) at 4km. I would be interested in seeing a comparative test of the Sunhans amplifiers

Awesome video! I really appreciated this. THANK YOU. After watching this, you sold me on this amplifier and just ordered mine about 5 min ago.

I have an identical one running 24/7 for 6 months now. Driven with 100 mw to get full 4 watts out into a panel antenna and it barely gets warm. Works very well and is the only solution that works after trying everything else. Highly recommended. Using it to view this video and make this comment....;-)

I've been having a lot of fun watching your videos, experimenting with antennas and actually having good results. Recently I purchased an Alfa card from eBay and now I get 100% signal and -45dbm atenuation, whereas I used to get 80% and -55dbm with a 7 turn helical connected to my laptops wifi card (20% signal with -81dbm without external antenna).

Thanks for this, perfect timing, I was looking at one of those just yesterday!

Very interesting peice, Andrew, gladly found you're excellent channel 👍👏💯

Great test!

Thank you for another great video. At 9:00 you highlight a spike which appeared to be in the 1800 MHz gsm mobile phone band and a very wide spread of frequency around 2.4ghz. Please can you give some additional information about what input signal was presented to the amplifier?

great video keep them coming

Using this amp with a much larger 9dBi segmented Omni antenna results in a cool amp. I've tried it as an AP and Station on a USB adaptor and direct to a TP-Link range extender. That is with various videos being run to load up the network. It works very well and drags in signals from across the next few streets. More than a 9dBi antenna on it's own. The bigger antenna is the best and cheapest upgrade. This just takes it a few steps further. I saw the vid on RF cables and the ones that come with the longer antennas have a mag mount and 1M or more cable. Ditch the cable and screw the antenna to the router, extender or antenna direct. Makes a big difference as measured on this channel.

Great Job, do you think these type of booster will work well with your Cisco 2.4Ghz Antenna. They are many boosters on the market, like Sunhans or Comfast 4W types. Which is the best

Next up will be double triple biquad in two barrel cantenna with dish 6000dBi

Great video,what's the life span of these when used recreationally on a rc radio?

very helpful, thank you

absolutely incredible. Thank you so much for taking the time to do the video and set up the jig. I bought 2 of those exact amplifiers and one 5.8 which was actually very hard to get but they all match and connected it to my drone which happens to be a DJI Phantom 3 4K. I was awfully confused as the only thing that I have to go by are the specifications as testing equipment at that frequency is way too expensive and I haven't been in the amateur radio game and a very long time. anyway my results were about the same as yours in the physical. I improved my Wi-Fi Telemetry and Video Connection as well as control about 20% to 25%. now comes the confusing issue , if I brought one tenth of one Watt to 4 Watts, how come the increase was only 20%? I know there are a lot of factors and I won't bother listing them but somehow I am wondering if I'm over driving the front end of this little amplifier. any thoughts? just getting a matching Network would probably be expensive if I couldn't build it and I don't want to put an attenuator on it as my fear is that it would then limit the receive which is absolutely essential in bipolar Direction. so frustrating but I only spent $24.54 on each amplifier compared to double triple or quadruple that of others with the same or less specifications. if you have any thoughts or suggestions to improve my results I would gladly make a donation. LOL

Would this also work on Bluetooth since BT it uses 2.4-2.483 GHz? Could you use a splitter to connect one amplifier to two directional antennas pointed in different directions?

is it really a 4 watt amp cuz all the ones i tested did not output the wattage they claim too.

I'd love to see more amplifier tests - I'd use one for the 13cm ham band. Would it be easy to add an external PTT for SSB? Don't they get to hot when operated on FM/CW? Btw: At 9:00 That out of FCC spec signal at 1.x GHz (on a UMTS band I guess) - You weren't still sweeping with the TG, were you? Garbage in/garbage out? :)

Will be trying this as a Wifi booster for camping. You can not boost what is not there but often the signal is weak. Using an external directional antenna and router, it will be interesting to see if it works.

would this amp higher the receive signal or it is only for sending signal?

what is that extra part passed the ground plane?

3:40 - That isn't a warranty sticker. That's just a quality check sticker they use to mark their products when they have been checked for quality, also for added reassurance to the consumer.

are the power amplifier chips connected on the chassis as heatsink?

hi when will you have your long range repeater back in stock!

Andrew, a friend of mineI purchased a 2000mW 5.8mHz transmitter from China for FPV. He realizes that it can't be used in the US but wondered what kind of range could he expect to get from the simple dipole antenna that comes with it. I don't know the Brand but the top reads TX52W, It has a built in fan, a small blue LED inside that lights up when power is on, it also has a number of inputs and output pins marked S-CH | VIDI over S-V | VID2 each section has 3 pins over the top of the markings. A second set of markings and pins to the right of the first have the normal pins for an FPV transmitter sound and yellow red and black wires with voltage ranges from 7-24 volts. Speaking of sound, you sound like you're in a mine shaft, very muted, lots of bass, you would sound much better with mid-tone and high tone treble...

Would it probably work better if you put a heatsink on the chips?

Hi Andrew! great video :) I´m living off gridd in a remote area and used to enjoy internet through a simcard in a4g LTE 300mbps wirelss router. It does not have external antenas. As of few weeks back my connection has been terrible and offline most of the time. How can I do some home made improvements or make an antenna of some sorts to amplify? Perhaps youve made a video on such a thing in the passed but I wasnt sure which one it was from the list. Thanks for your efforts and be well :)

Andrew, you said this gets hot and that it may go pop if the swr is wrong. So must I not use it with an Alfa and home made sat dish with cantenna?

hello i have same booster how can i underestand is it working or not becaouse when i connecting power i cant see led indicators light is it broken ? :(

I've warenteed a couple of things back to Chinese ebay/alibaba vendors, never had a problem. I'd say they were actually a lot more helpful and a lot more interested in keeping me happy than most vendors from my own countries.

What if you ran two of these together in tandem would you get 8wt

The green light is flashing. Is dat good. Thanks

I have one of these Amplifier, the red led get on and also the green one is blinking, but the amplifier doesn't take more than 60mA and never get warm. what is the problem with my amplifier?

do these amplify the recieving signal aswell?

i was just wondering if they not only boost the signal outgoing.. but do they boost the incoming signals too?? and if you don't plug in the power to the amplifiers can the WIFI device that's getting boosted still receive signals still even with the amplifier off?

Andrew McNeil ...great review and test! I have two on the way from China...my question is...this product has a maximum trigger input of 20dbm which is low to my understanding about 0.1w ...does this mean I cannot send a stronger signal to it? I'm in a CE region which is 23dbm 0.2w ...but fly quads and have my birds talking in 1.5w and have to have my RC throwing out the same if in that mode....can you please give some insight...cheers

what about using it with the x9d taranis radio? would it work well?

Can it be used with ALFA wifi AWUS036NHA to amplify range ??

so this is of no benefit connected between an Alfa and antenna?

hi Andrew. I have one of these and have just popped it. put the - and + the wrong way around. could you read the chip I'd on the 6 legged black chip nearest the power input jack for me? this has popped and is unreadable for replacement :-( thank you bud :-)

Can you use this booster on a usb wifi card ?

So if you amplify the transmit but not the receive, then what is good about that? If I have this connected on my router, that doesn't necessarily mean I can have a longer range coverage if the receiving end isn't also amplified, right? I mean my remote device, like my wifi connected cellphone/tablet, would be able to see my router BUT it would not be able to connect because the transmit signal on my phone/tablet wouldn't be strong enough for this amplified to pickup, right?

Thank You 4 do'n a amp review!!! Do more! there are so many cheepo amps out there i don't know what 2 get.

can i use external antenna with this ...

Great job. I like this product and I will try to my router

Great video :) subscribed! i have ordered a dual band antenna for my dual band phantom 4 pro controller, i would like to boost the signal .. is there good dual band boosters like this that will auto switch between 2.4 - 5.8 ?

Is there a 2 antenna version

does this work with dual band?

Can an alfa support an 8w amplifier??

Nice video

question.. I do not own any 2.4ghz analyzer or a wireles router with a removavle antenna.. so I'm not quite sure if this device is transmitting or not.. now I've notice that there are two led lights on the booster.. What does the red and green light mean (red= transmit abd green = receive ?!?) I'm going to use this to get more range on my FPV plane..

I can't see how wide that noise spike is under your cursor, but it's close enough to 1.8GHz which is/was a common Intel clock speed - any chance at all that this is coupled in from your PC?

i have one of these. running for 2 years, i do have it bolted to a bar of aluminium as a heat sink

How can i get 2.6 Ghz booster?

how i can buy its? shoppind link plz

it works on cotinue power 1 year 24-7 so far so good

What kind of connectors is it using on the input and output side of the booster??

Sir Andrew, i hope you don't mind me asking question about how much a typical mobile phone's 3g, 4g receiver's wattage or power is using. i been trying to build and calculate the size of an antenna base on its wattage to maximize its receiving capability. it doesn't have any marking of how much wattage it is using. and when i googled it, i got confusing variety of answers and i wasn't sure which. since you aare a pro in this area of studies, i take the opportunity of asking you this. I've been following and watching your videos, and i have learned so many things. thank you so much for making such informative videos for people like me with very limited tools to use.

Sunhans Amps 3 watts or better are far superior with N connectors and lmr 400 cable to limit any signal loss Andrew. Sunhans are the real deal .

What about mounting it to a larger heat sink? fan cooling?

What voltage used to power the unit? 12 v ? Can I power it with 9 V ?

what inside the box, can you show me

where do I get a 2.4ghz booster for transmit and receive which is reliable? It need not be as high powered as this. Thanks

Could affect ADS-B equipped aircraft with that 1GHz spurii!

May I know if it uses its own spectrum and disturbs the frequencies within the vicinity? What is the different between the wifi signal amplifier and cellular signal booster? I really need your answer before I buy because in Malaysia cellular signal booster is illegal and could be fine up to RM 500k.

Im also interested in more booster videos

In strapping that to the back of my quad-copter transmitter - how is it then powered?

how come your "wifi meter" went from 3/% to 2/5 when you put on the amplifier? is the signal noizy?

It`s the best test of amplifier!!! I always wanted to see characteristic of 2.4GHz amplifier and all it noises with spectrum analyzer. It is very helpful. Could you test the speed of connection with this amplifier? Can it correctly work with high speed standards like 802.11n or it reduce speed ?

What about a couple of beefy heat sinks?

Little confused...!What is the main purpose of this amplifier? For recieving signals or transmitting signal..??

how about giving it half the voltage for half the power but a longer life?

band 3 is 1.8Mhz, can you use this to amplify the LTE signal in your opinion?

It will interfere with tacan and dme aka navigational equipment for aircraft.

Hello Sir, which one of them is better? Sunhans 2500mw or 4w booster from china?

I've just bought this edup 4w amp as an upgrade and pleased to see your test shows it outputs the claimed power, have you ever tested the turbowing RY-2.4? I've had one on my rc transmitter for a few years and its not clear what they output. Sellers state it as a 1w amp but the manual says its 1w in one part and 2w in another part but opening the unit and looking up the output transistor brings up a part that can output 2.5w. I've always been sure its kicking out more than 1w. Another module I'm interested in knowing about is the Wii-link XQ-02A which claims 2w from a 100mw input, and thinking of using them as part of my open HD FPV system as they are very lightweight and can be carried on board a plane :)

Problem with these is they kill the receive signal try doing a scan with and without there's a massive difference

I will buy this amplifier and i will use it with alfa awus036nha for fake access point. Can this amplifiar work properly for me? My alfa is already 2 watt. Is this problem?

Very nice video 🙏😊 would be great to see more videos about 2,4GHz Amplifier maybe with this much china pcb s without case from 10-30dollers Regards from Germany

Can this be used in radio transmitter?

I bought one of this after this review. Added an old AMD heatsink on its bottom to play safe and it really did improve my connection a lot. Fuck my neighbors, I'm pretty sure two of them have a couple of these things too.

Compare them to Sunhans 4W 2.4 and 5.8GHz please. You will notice a big difference.

Hi friend..! What does this amplifier do?? It is used to broadcast wifi signals from router to far distance ?? OR It is used to catch weak long distant wifi signals and fed to laptop wifi adapter SMA port ??

The unit of measurement for power is Watt, denoted by a large W. The Chinese note the units of measure with w or W as they do not distinguish uppercase letters from lowercase letters - they have a different alphabet. I watch your videos and I appreciate them. Are you Chinese? James Watt was Scottish, en.wikipedia.org/wiki/James_Watt and www.britannica.com/science/watt-unit-of-measurement.

its ok direct into yagi antenna

where do I get one, please?

getting the 2.4 ghz wifi booster for the drone i have

is this legal to use with a foundation licence in the uk?

Hi: Can you explain to us about the antenna being a dipole & not a vertical? If your antenna is a dipole then polarization becomes CRITICAL but I’m pretty sure your antenna is a vertical which would be omnidirectional. Thank you VE6??????

This was on 24/7 I'd mount a fan on it

The eBay link no longer works

On the evening he puts his tx next to a can of soup and voila hot soup

Don't buy this thing if you want faster internet or longer range with flying thing. Buy this if you need amplification with massive amounts of noise. Yes you can see much more access points when scanning but try test speed. Speed test shows extremely poor speed even with close APs because of noise. And for fpv forget it. Tested in both environments.

water cool it ;)

Give me a $0.05 capacitor and I'll give you another bogus product that turns your house wiring into an antenna LOL.

No CE mark at all, not even the fake 'Chinese Electronics' one. Should it be allowed to go through customs at all?

You English worry to much about your wall plugs!!!!! We here in the Good Old USA we don't have the fancy plugs to protect us from getting electrocuted. We have been taught not to touch the plug prongs when plunging items in!
