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.

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.

[@letitrotfuckit]

it cannot work. It cannot even transmit. The antenna is connected to the base of the transistor which doesn't even make any sense in the first place. Not to mention that the circuit has not even been soldered together on the video and one can clearly see the leads from the LED going out to the side to a batter hidden under the cellphone. Then propagation conditions improve and the signal bar shows full. or the phone was just move to a spot where the signal is full bars and it took some time to update the status. The circuit probably will generate a bunch of week garbage harmonics on 20 mhz and that's about it.

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 KZbin 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.

[@CowMowTV]

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.

On older phones, which may just judge the signal strength by the raw strength, it could show more bars. On 3G and 4G devices, this will not work because the strength is calculated from the actual strength, signal to noise ratio and bandwidth (for LTE 1RB equals 200kHz of bandwidth).

Use Avometer model 8 to measure all high frequency parameters. Better too use the shortest Palladium test leads you can find to reduce parasitic effects. Clean the copper with a mixture of acetone and vinegar to ensure best results. Oxygen free copper will give your calls the best audio quality however silver plated gold will improve the Q factor due to reduced skin effect but reduce the audio fidelity. It is better to make the connections with silver brazing to eliminate voltage gradients due to the Setback effect. This circuit is great. It even works for wifi.

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.
