The frequency is in giga hertz, , all the coils shown r fm frequency range . this r all radio machanic design, it will certainly not work , he is fooling all , this is another fake video like many so dont waste ur time & get fooled

Great circuit. Used it on my microwave oven and it now cooks in half the time.

There are so many things wrong, I don't know where to start. However, there are a couple of obvious problems. With the antennas so close, you will have feedback and the 2nd stage appears to be an oscillator at 20 MHz or some harmonic. What I see there is an interference source and not a "signal booster". BTW, what you called a crystal oscillator is in fact just the crystal. Also, that transistor is only rated to 800 Mhz, so it won't do much for WiFi or the higher cell bands. Fire up a spectrum analyzer to see what that's actually doing.

Граничная частота транзистора ниже рабочей частоты сотовых телефонов,не говоря уже о том,что транзистор должен иметь запас по частоте в 2-3 раза выше (примерно) для нормальной работы.катушки индуктивности намотанны как на 88-108 fm диапазон метровых волн,в то время как сотовые телефоны работают на сантиметровом диаппазоне ..) эта схема не может быть рабочей )

Сделал теперь, не только сотовая связь заработала без сим карты, но и вай фай раздаю, без лимита 🤟

I built myself this circuit, connected to my car battery and now my petrol car runs entirely with a simple CR2023 Battery. It`s magic

Только от русскоязычных товарищей объективные комментарии 🤣 Все остальные благодарят и по ходу бегут за паяльником и проволокой

So great with this circuit. Before I was bald and now this circuit has brought my full head of hair back. Amazing.

Классная вещь. У меня даже чёрно-белый телефон в цвете заработал.

What a fantastic tutorial! The cell phone signal booster is incredibly easy to make and has so many uses. Strengthening the mobile, Wi-Fi, radio, and television networks with one device is genius! The detailed instructions and links to purchase components and view the circuit diagram are very helpful. Thanks for sharing this valuable project!

This circuit is great. It even works for wifi. Signal increases 2 bars and no more disconnects. Also on it close to digital tv antenna no more picture breakup. I put it next to my auto engine. Mileage to up 10-15 mpg and lots of power. I put it on my pillow at night now the bald spot on my head is growing a lot of hair now. Also missing 2 tooth in front new one grow back. Wife too small on top put circuit in her purse now like mountains but problem now she poop a lot. You should build on black box sell make a lot of money.

Почему так мало дизлайков? Бредовые выдумки гуманитариев побеждают здравый смысл, даже если схема изначально не рабочая?

ВЧ контуры больше на УКВ диапазон, чем выше частота тем меньше витков. А гегагерцовых частотах там контур вообще просто провод,

Señores en vez de estar criticando tanto miren el lado practico del circuito, el trabaja en base a los harmonicos de la frecuencia principal y con relación a las antenas cerca una de la otra los routeres comerciales las tienen mas juntas y trabajan excelente; y si se pueden usar otros cristales de frecuencia. la primera antena toma una parte de la frecuencia de entrada y en la segunda antena con el cristal como referencia se mezclan y a la salida tenemos una frecuencia que esta dentro de la cobertura de la red en el celular dando la ganancia necesaria.

Бред. Как может приемная и передающая антенны стоять вместе. Он сразу в самовозбуд уйдет

Hi, It seems that this circuit could not be working due to the oscillator frecuency of 20mhz, I know that cell freqs are over 1000mhz or 1Ghz, this also applies to Wifi signals. It shall be reviewed and fully tested.

Wow! This circuit works just as well as a cell phone sticker booster antenna. 🙄

As an engineer every observed and written comment is correct! Simple thing is if you hear this music just close the video!

Не было показано как он спаял схему, по принципиальной схеме ли? Вообще есть ли там припой, кроме как на одном резисторе и светодиоде, про максимульную частоту транзисторов уже написали, антенны близко расположены, по идее одна должна быть например на крыше, другая в помещении.

Good thing, I use this to upgrade my neighbour from 4G to 5G

А где смещение базы второго транзистора? Это работать не будет!

This is as if it were a result of a false positive test.... You took the transmission frequency nearby, amplified it, and the cel in the search for frequencies understood that there is a stronger signal nearby. But this does not mean that there was an effective expansion in the signal transmission and reception system.

LED realy works!! Good micro flashlight ))))

Парень, тебе нужно лечиться...

Watching Sir idol new viewer here. Thanks for sharing your knowledge!

Схема не рабочая. 1 - монтаж с паразитными связями на вч. 2 - паразитная обратная связь между антеной передатчика и приемника. В результате нет усиления полезного сигнала.

This MIGHT show an increase of the RF signal to your phone, but without a frequency counter, how do you know that it is on the RIGHT radio frequency for G2, G3, G4 and G5. As in the UK, they use 9 different radio frequencies. As they use BAND 20, and that is on 800MHz, and on BAND 8, they use 900MHz, on BAND 32 (SDL) is on 1400MHz, on BAND 3, they use 1800MHz, on BAND 1, they use 2100MHz, then on BAND 40, they use 2300MHz, on BAND 7 (FDD) they use 2600MHz, and on BAND 38 (TDD) they use 2600MHz, and on BAND 42, they use 3400MHz. So PLEASE tell me on WHAT band that this so called MOBILE SIGNAL BOOSTER ???? As I say, it might show some form of RF (Radiated Frequency) that will show MORE bars on your phone. But a TRUE signal booster is NOT just a TRANSMITTER, as it needs to be a TRANSCEIVER. That is a transmitter and a receiver built into one unit. Also the distance between the two aerials is a BIG thing. As if it is TRANSMITTING and then RECEIVING the same signal, it will form a FEEDBACK LOOP. You know if you hold a microphone next to a speaker and it makes a very bad noise, that is an AUDIO noise, or just think what sort of interference that it will make in a silent radio frequency ? To tell you the TRURH, it is a crock of $h1T. As I say, it will show MORE bars on your phone, but in NO WAY 🙅‍♂️ is it going to pick up a mobile signal from a cell tower to boost it to your phone, then simultaneously take the mobile signal from YOUR mobile phone and RETRANSMIT it as a BOOSTED signal back to that mobile cell tower. It all looked GOOD and he even uses a crystal that is used in radio transmitter equipment, right down to him making a technical looking circuit diagram to make it look as if he knows what he is doing. I can put a strong 💪 signal to my phone, by using a rough metal file, some wire and a 9 Volt battery. As connect one wire to one of the terminals on the battery, and connect that to the metal file, then connect the other wire to the other terminal to the other side of the battery and run that wire up and down the file, it WILL generate a radio signal, that will cause a load of electrical interference on radios, and on TV’s, and will have some affect on a mobile phone. So for you to generate a radio signal is VERY easy. Do NOT be taken in by STUPID people that just like to get subscribers and also to get likes. I only wish that RU-vid had a TECHNICAL department, some people that know about electrical generation and radio signal BOOSTING. Then they will NOT have people posting videos like this.

Pretty slick. From many data sheets of power diodes (1N4001 for instance); if you reverse the applied voltage at about 0.7 volts, the diode will act as a small amplifier. From the data sheets, linearly applied voltages will cause the capacitance of the reversed diode to vary in a logarithmic fashion. Boggle. I have such an amplifier ahead of the antenna of my TV. A two stage powered by a 9 volt battery and the over all circuit draws about 0.800 milliamps.

Thank you this video big information and idea I do also

Скорей эта схема самовозбудится и будет глушилка, а не усилитель :))))

The circuit diagrams in the video and in the blogspot web site are very different, however both are dysfunctional.

Контура не те, приёмная и передающая антенны слишком близко. Транзисторы ВЧ, а не СВЧ. Ёмкость монтажа дикая. Оно точно должно на СВЧ работать? Да и там где хотя бы 3 палки ловит без труда можно поймать 4.

How did you connected board with supply how much volt have given

This circuit does not work. The video was cut off during the signal change.

To boost cell signal you need an antenna with high gain and a powerful amplifier

I am reminded of this miracle medicine that cures all diseases and gives eternal life. :)

just what the doctor ordered thanks.

Если бы все так просто было, то и в улучшения связи операторы не были бы заинтересованы: сами бы продавали такие приспособления к телефонам

What is the DBM of the network, this circuit will work well, please tell me, I am speaking from Bangladesh

Variable capacitor??????????????? Value?????????

To boost cell signal you need an antenna with high gain and a powerful amplifier. This is impossible in your circuit

The joy of inductor coils.

Although I am not gets good understand the fantastic board but overall the video was informative

I tried to like, but received a message that the amount of likes has reached its limit (?)

Тили тили, Трали вали , нас похоже наъбали. Параметры не соответствуют рабочим диапазонам мобильной сети сотовой связи.

Hola muy buen proyecto,se podrá utilizar antenas de router wifi para ampliar a mayor alcance? muchas gracias

gsm signal boosting is not possible with this circuit story

Wonderful no connection no soldering

how do you match signal impedance with circuit impedance when you do not use a signal network?

Does it work both ways you can receive a signal but can you transmit back? Maybe you need a transmitter also.

I just reported this video to RU-vid as "misleading ".

Сижу дома с травмой руки (одной 😁), тоесть времени вагон. Детали имеются, схему спаял, не работает 🤣🤣🤣🤣🤣🤣🤣.

А где смещение на базу транзистора кварцевого генератора???

3:10 in case there's any newbies watching - that's called "proto board" or "perfboard".

Can you show the back of the win, the back-of-the-win wiring.

Hope that gives me the answer to my question. When making this device, how often does it handle?

Ну где бы я ещё так поржал, как не в комментах под подобной вундервафлей. :) И ведь тип набрал свыше миллиона просмотров. :) Наверное потому, что в Индии народу много, и физику они в школах не учат. :)

Hi thanks a lot for this Circuit, the booster has an input and an output, right? But doesn't the booster have to work in both directions?

اخي يسلمو عل شرح . بس ممكن تنزل فيدو عن اليه عمل هذه الدائرة ؟؟ وسؤال ثاني كن تردد هذه الدائرة (تردد ال2g(

Die Idee find ich gut. Die Schaltung ist wahrscheinlich schmalbandig und nicht besonders stabil. Der Quarz soll wohl Kurzwellen Signale unterdrücken, das wird mit dem schmalbandigen Serienkreis des Quarzes kaum funktionieren. Ein paar Worte zum Abgleich wären hilfreich: Mit der Handy Signalanzeige auf maximum Level drehen und dabei ein Video beobachten, wegen der Bildqualität.

Узнаю брата Васю! Очередной сын лейтенанта Шмидта. Namaste.

धीचिक धीचीक music के बजाये आप अपने voice ki jariye सभी circuit making ko explain करोगे to अचा Hoga

Yo desconozco de electronica, pero el video no es continuo. Cambia cuando sube la señal, es otra toma y se ve perfectamente. Entonces, no creo que en la practica funcione.

Today on this channel: How to make electromagnetic interference (EMI)🤣

Dear bro it is true, why not sale in hand brand model. What price i ready to purchase.

Ready mede which site available sir

Маловероятно что заработает!

Why was there an edit cut right before the 5th bar came up. Also bars are not the way to check signal strength, they mean nothing really. You need to check your dBm levels in your settings. Keep in mind he's selling kits too. Fishy.

At time point 6:27 there is an unusual sudden change in the video recording; from time point 6:28 upward it appears to be another video clip which was merged to first one (from 0 to 6:27). A suspicious movement was made at the time when the fourth bar showed up.

I expected brown hands in this video, but you was able to surprise me, man. You definitely have to make more vids about magnetizing gas, speeding up windows, working lot57895tery strategy, and 482Hz music. You’ll get million views!

انا موضحتش وصلات الدوائر بعضيها عملي انا مافهمتش حاجة.. وبعدين انه الاحسن هذه الدائرة اللي بالفيديو ده ولا الدائرة اللي بالفيديو اللي انت عملته قبل كده

1stage supposed to be rf amplifier is a dummy unit...will not work. The aerial circuit is not selective and will not pick except high power local redio stn at medium band.The second stage is an oscillator that may work at higher harmonic frequency of 20MHz ! depending upon the tuned LC tank circuit.Expect that frecquency as output that must be below cut off frequency of the Transistor used. Here there is no issue of ultra high frequency used in mobile phone TRX. I dont know the purpose..a gadget!

Necesito la lista de componentes como puedo hacer eso ?????????? O enviarla en documento work

ok thank you sir👍,, 😊

Si su escritua fuera mas claro seria magnífico como guia para seguirlo..peto esta hecho un relajo

Htis is fm tranceiver! Video fake!!!

el q 2nolleva polarizacion en la base?como va a funcionar asi?

This will not really improve the signal strength, but might trick the phone into staying in a certain cell, because of the crystal harmonics. The transistor doesn‘t work above 400 to maybe 600 MHz.

Пойду клепать и продовать на авито. Главное чтобы не поймали

The inductors used in cellphones are of the size of MIlimeters Or less Do you Really think it could come in 1200 or 1800 GHz?

So one side of the circuit generates noise, and the other half is a cell signal jammer, rather crude and illegal, does the french government know you are using this?

Работаeт только LED.

Sar mobail me Keye se network settings ho ga

А где по схеме стоит 2 ой 200ком резистор

Проще пареной репы,накручиваем пружинку, припаеваем к адронному колайдеру и запускаем пару десятков спутников.

I have question, what with element ANT1 and ANT 2, because it probably won't work

Bhai mujhe network problem hai. Maine yah banaya hai yah Kam nhi kar raha hai. Aap kab online rhate hai mujhe shvar ka jvab chahiye. Please 🙏 help me

И печатка на пальце рандоль!)

You can't even defend your circuit to the bashers.

Bhai saab where you have given power connection to work You have given a separate connection(irrespective to pcb connection)to the light so that the light is glowing😂😂😂

Total nonsense ! I am an Avionics/Radar engineer latterly working as a sytems engineer on P-P wireless and 2G 3G radio. This could never work, the active components used couldnt handle the frequencies involved and that aside 2G 3G and 4G use completely different frequency bands anyway so one size could not fit all ! Assuming it did work, you would be re-transmitting a cellular frequency which would be illegal as you would not have a spectrum license to do so.

Usualy to proof the circuit is working well needs to be build by a third person .Is there a person who did it.? Ad an experience of your about it.

FUNZIONA!.. (ma bisogna credere nei miracoli celesti..)

Да ну, что за фейк, и работает(?) правда?

Это не Дмитрий Компанец случайно?

In your 1st nd 2nd attemp your signal is not responding, but in 3rd time i saw a timeline cut, More practice on editing.

اريد ان اجعل الجهاز اقوى اكثر ماذا يجب ان افعل هل زياده الكريستال مثلا بدل 20mhz تكون 30mhz او ماذا

ओ भाई प्लेट तो बता दे कौन सी खरीदनी
