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

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 )

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

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.

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

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

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

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.

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

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.

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

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

Парень, тебе нужно лечиться...

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

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

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.

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

The joy of inductor coils.

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

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.

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

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

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

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

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.

может это усилитель ФМ сигнала, для радио или еще какой безделушки ?

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

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

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 KZfaq 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.

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

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

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.

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.

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.

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

Bom dia, seu vídeo é ótimo, parabéns, Deus abençoe.... Alagoas-Brasil

Also receiver and transmitter antennas 9n traditional ones seems some but in fact are seperated. 2 wire of coax cables one is of receiver and other transmitter signal, at end they are connected but thats because after signal is out it seems that cable being connected doesnt matyer ;)

Can i use different crystal like 24Mhz or 17Mhz..i don't have 20mhz?

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

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?

The 2N3866 is a low power consumption NPN silicon transistor designed for VHF and UHF devices. It is suitable for oscillator and frequency multiplier functions. Frequency range 1- 400 Mhz, and I think if it really works, if it is allowed in Germany ? :-)

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

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

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

А где по схеме стоит 2 ой 200ком резистор

please this booster how many meters can broadcast signal ? is it public for 50 m2 squire meter?

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. :)

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

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

Thanks for the idea,but can we use an Osillator of 27Mhz please???

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

Thank you this video big information and idea I do also

ok thank you sir👍,, 😊

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

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

Sirve para amplificar señales de FM?

Consulta sirve para cualquier celular??

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

sir papaano ang pagkonekta sa bawat terminal ng peyesa?

AC circuit board kitne ka milega milega sir

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

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

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

المنطقه اللتي ان فيها لايوجد 3ج ولا 4ج ...2ج فقط هل يرفعها الي 3 ج علي الاقل

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

Como se podrá conectar a una antena aérea?

How about TV booster, do you have it?

شكرا صديقي أين ممكن اجد هذه البوردة

How about some spectrum analysis data?

Receive signal booster only, no transmitter booster as needed in mobile network both way communication not only receive.

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

Excellent as a circuit, he can even get me a six pack at the Seven.

What is its range in a room where we mount it and distance it cover between mobile and booster

Muy bueno, los transistores que pude conseguir son C9014, se podrá hacer con estos?

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?

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

Ready mede which site available sir

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

Маловероятно что заработает!

this board can not operate. Only receiver signal that not transmitter signal. Is that FM signal booter ?

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.

Wonderful no connection no soldering

Lo voy a hacer, gracias

the music,,,,dont think it would work,,,,can i bill you???/

كم يبلغ مدي عمل الدائره هل يوجد ما هو اقوي لان الشبكه عندي شبه منعدمه

gsm signal boosting is not possible with this circuit story

Is that just for iOS through will this work with Android also?

If I understood everything correctly, then this device can be used not only as an amplifier but also as a signal transmitter.

Sar mobail me Keye se network settings ho ga
